Yaris/Scion & Vitz :: 2002 Toyota Echo - P0171 Code Thrown While Idle
I have a 2002 Toyota Echo. I just purchases a Creader V code scanner. My car is throwing a P0171 code. The light only comes on at idle or while going under 10 mph.
The data from the reader was:
Trouble Code: P0171
Fuel System sta B1 : CL, using HO2S
Calculated Load: 11.76%
Coolant Temp 188.59 degrees
The Freeze frame data was:
ST Fuel B1: -3.91%
LF Fuel B1: 36.7%
Engine speed: 795.5 RPM
Vehicle speed: 0 mph
Intake Air Temp: 82.4 degrees.
I went back today and ran live feed on the O2 sensors. I'm not sure what STF of O2S: STF means. That was another figure displayed on my code scanner.
The O2S S1 was reading between .04 and about .82. The graph looked pretty normal (I guess) in regards to going up and back down between 0 and 1. I don't know alot about mechanics, but I seen a youtube video of a graph showing it going up and down and what is normal. Mine did that on S1.
O2S S1: STF was: 3.89 and -1.57%
O2S: S2 was a different story. It was between like .58 and .66.
The O2S S2: STF didn't give me a value at all. It just said " --% ". The graph of this was slowly going up but in a small range. It started at like maybe .4 and would go up to say .5. The next wave would be like .45 to .55, then .50 to .60, then .58 to .66 etc. So it was not ranging just between 0 and 1. It had a very tight range that gradually increased upwards.
I built my own smoke machine before testing with the code scanner and I didn't get any smoke coming out of the car except for around the air filter housing where the lid meets the bottom portion. I don't know if it's because I had the air filter wrapped in plastic wrap. Can I have an air leak where the filter cartridge connects that would case a lean code P0171? Maybe I should go try to smoke test again. I did it about 3 weeks ago and I can't recall exactly where I had the smoke going into. I thought I disconnected the PVC hose from the brake booster and plugged it in there. I assume the smoke would get thru the whole system. It took about 2 min before the smoke came out of the filter housing.
The car only sets a lean code at idle or going less than 10mph and I'm coasting in a residential area.
I have an inspection coming up in May and need to get this thing fixed before that. I can't find any other air leak, but I wasn't sure a leak around the filter would cause this and I'm not sure the leak wasn't caused by the plastic wrap.
I'm thinking my only other prob could be fuel related. Fuel filter, fuel pump, clogged injector, or can my O2 sensor be bad and causing this? I've already replaced all spark plugs and coils as well as the PVC valve and cleaned the MAF sensor with the appropriate spray.
The car runs ok. The exhaust seems to smell RICH. Like Gas. I don't think my fuel economy is as good as it use to be. It has dropped from as hi as 42 mpg to between 38 and 40 if I'm lucky.
Back when I was having problems before and realized I had a bad coil, I had tried some injector cleaner. Why the codes were back then, but I had erased them and the car ran fine for about 2 months and the light came back.
My MAF sensor was .14 lbs when I was watching the live data above. I plugged my fuel pressure tester directly into the fuel line coming from the fuel tank and got a reading of between 42 and 44 lbs (car not running, just by trying to turn the engine over). I don't know if that is as accurate (or useful) as having the fuel pressure tester on the car and in line to allow the car to start up and run and watch the tester. I have to wait until my part comes do run the test that way.
Yaris/Scion & Vitz :: Toyota Echo Motor Start To Idle Really High For A Couple Of Minutes
I've always find solution to solve my little issues with my Toyota Echo 2004 Hatchback. Since last summer, my car seems to have a lot of problems to idle well with the fine rpm. Here are all the events :
-it all started last summer, when the motor would start to idle really high for a couple of minutes, before getting back to normal. When this happened, a p011 check engine would light up. I switched to synthetic oil, and it greatly reduce the number of time this happen, but it didn't solve it entirely. It usually happens when the motor is warm, but still not hot.
-Only once, during a long ride, I got a check engine. When I left the highway, my motor wouldn't stop idling high. stop/start the motor wouldn't change anything. I checked the check engine codes, if I remember well : p011, p016 and misfire. With a friend, we checked the crankshaft sensor, and it was really dirty, so we washed it, and it solved the problem! A few days after, I also change my spark plug because they were starting to be old.
-A few weeks ago, I started my car and it was idling high as usual to heat up faster (it is winter now). But then, the rpm suddenly drop really quickly. The rpm was really low for may be 2 seconds, and it nearly chokes, but just before it went up back to normal. Then low/high/low/high until the motor was hot. No check engine. I disconnected the battery for a few minutes, and when I reconnected it, the problem was solve. I also checked the air filter, but it wasn't dirty.
-Then, sometimes when I start my car, idling is fine but suddenly at a red light the motor start to run really low with a lot of vibrations and a bad smell. Stop and restart the motor solve the problem! But only until the next red light, or until the motor is warm enough. Still no check engine.

I have a Toyota echo 2001 , manual 4 doors, My question is about when I climb a normal road the engine lose force the I reduced the speed form 4th to 2nd in order to continue my way, It is like the car is towing a truck, It s turns very slow. My question IT IS NORMAL?
The ECU only shows the 0420 Code And I know that It is about the cat because I replaced it for a generic. And the O2 secondary sensor voltage is like a wave.
Yaris/Scion & Vitz :: 2003 Toyota Echo Starts And Runs Good But Stops When Warm Up
I have a 2003 Toyota Echo with 250,000 miles. It has been a great car as I commute 90 miles to work. I have had no major problems with the car. Unfortunatly it recently died on the way to work. It was running great and then all the sudden it sputtered and killed. When I first tried to start the car it would just turnover but after waiting 10 minutes it started back up (this was a cold morning). When it started it was running great again. I drove it another 15 minutes and it all the sudden died again. This happened 3 times.
I have hooked up to a scan tool and a camshaft position sensor code displayed. I replaced that but had no change. Another code came up as mass air flow sensor. I purchased a used one of those and still no change.
I have started the car up numerous times and always have the same results. It starts right up, idles good, speeds up good and runs good at full throttle. The problem becomes when it warms up the car kills. If I run it at idle to a slow acceleration it takes longer to kill than if I run the car at full throttle. Once it kills it will not start up until the car cools down, but once it cools down it will start right back up.
Yaris/Scion & Vitz :: 2003 Echo Throwing A Cylinder Misfire Code / Idle Rough
My friend has a 2003 Toyota Echo that is throwing a cylinder misfire code. Original code is P0302 and P0302PD. The car is idling rougher, kind of sounds like "put-put-put". Also, the car has no power at all. He lives on a hill and he can't even pull out of his driveway. Lastly, the smell of the exhaust is gassy.
We have changed out the spark plugs...no change. Next, we bought a new ignition coil for the number two cylinder...no change. So, maybe its the wiring. Put the new coil onto the number 3 cylinder and the number 3 coil onto the 2 cylinder. Low and behold, the misfire code changes to P0303 and P0303PD.
Thinking we might have gotten a dud of a coil, we bought another. Same thing...new coil on 2 code is P0302...new coil on 3, code is P0303. Could we just have gotten two bad coils? Oh, coils were a BWD brand coil and Duralast brand. Should we just go OEM from dealer? OR Denso from Advance Auto?
Yaris/Scion & Vitz :: How To Empty Or Remove Windshield Wiper Fluid Bottle From 2003 Toyota Echo
I currently have summer washer fluid in my 2003 Toyota Echo's windshield washer fluid tank. I need to replace this with winter washer fluid within the next few days before the temperature goes below freezing.
When I pop open the hood, I see that the bottle is located on the left hand side of the engine bay. The bottle has a black cap with a picture of a fountain (wiper spray).
I have no experience working on the mechanics of a car. However, I would like to know the easiest way of replacing my summer wiper fluid with winter wiper fluid. The tank is currently full with the summer washer fluid.
a) How do I go about emptying the bottle completely without removing it?
b) If I need to remove the bottle and then empty it completely, how do I do this and what tools do I need?
Yaris/Scion & Vitz :: Echo 2003 - Check Engine Light But No Code
Recently changed a front pipe manifold on my Echo 2003 4doors Five spd.
Noise I was reporting ealier thread seems to have subsided somehow but I did not hit the high road again, since the repair.
But I have this check engine light that went off 3 days ago and stays on.
Tried 4 times to read the code of OBd II reader and it pulls nothing. As if everything was normal.
I changed the batteries but it acts like it does regularly and it shows like there is no code to pull out.
Could that be a Ghostly Check Engine. It is still on at the moment meaning every time I drive the car.
Yaris/Scion & Vitz :: 2003 Echo All Coils Bad - Engine Lost Power
I was driving home and I lost power in my engine. When I gave it gas you can hear it miss fire and loose power I got it home and it starts and idles but not smooth. What should I be looking into at this point? I'll check the coils and plugs now but I'm not sure after that. I heard about a bad ecu but it still runs so idk.

Just bought little Echo and it's blowing hot air when the ac is on if I turn the ac off with the selector in the blue it's still hot. I used the gauge off a old ac recharger can and its showing the right amount of Freon and the compressor clutch is spinning. I am really wanting to fix it cheap , since I got it for 1200.

Mother in laws car had a bad misfire that goes away during idle. It seems to misfire during take off or slowing to a stop and Intermittently during cruise.
Came in with codes p0300 - random misfire and p0304 misfire cylinder 4
What I have done so far.
-Checked the oil
-Checked the plugs - they were bad so replaced them with ngk plugs
-part number - BKR5EGP
Misfire was showing in cylinder 4 on live data still
-Swapped coil 4 and 1
-Misfire moved to cylinder 1
-Swapped cylinder 1 with 3 to be extra sure and mis stayed on 1
-Swapped back to 4 and even 2 mis stayed in 1. Weird
-Pulled all plugs and checked compression getting 170psi
-Swapped plugs around in case 1 is faulty no luck
-Swapped number 1 and 2 injectors with no change.
So my thoughts now are leaning towards an ecm or a valve thing but would those not be on or off fails? It idles great and cruises great it's only bad we coming to and leaving stop.
Yaris/Scion & Vitz :: 2003 Echo Running Rough At Low Speed - Engine Light Blinks At Acceleration
My car is a standard and was working fine not indication of any troubles. Stopped and pumped $20 gas. Started to drive and car starts running rough especially at low speeds. Going up hill is brutal. Engine light flash when trying to accelerate, slow getting up to speed, shudders- not a lot of power, once up to speed engine light turn off.
Press the gas to go up hill- engine light comes back on and it begins all over, it also sounds like it is not running on all cylinders.
Is there any suggestions: fuel pump, fuel injection...spark plugs and wires? Something more serious
Yaris/Scion & Vitz :: 2000 Toyota Echo - No Reverse Light
I'm troubleshooting my sons 2000 Echo with a manual transmission. No reverse light. Very puzzling? The red wire with blue stripe in the trunk area is always hot. Makes no difference if the shifter is in reverse gear or not. Yet, the reverse lamps don't come on. I removed both bulbs and tested them at the battery using jumpers. They both come on. I have not gone under the car yet. My question is: does this car have a neutral start switch, and a back up light switch. If yes, which switch is feeding the other? Any pictures of where these switches are located? My guess is that the back up light switch is faulty, if there is one.

I have taken this problem to the dealer 3 times in the last 6 months and they claim not to notice any vibration or rattle. However, whenever I am at a stop sign or stop light with the car in Drive (automatic trans), a loud vibration sound can be heard and also felt in the steering column and the brake pedal. As soon as I press on the gas pedal again, the vibration goes away. The only other way to stop the noise is to place the car into Neutral. What might be causing this? Apparently, the noise is not audible outside of the vehicle since none of the techs at Toyota were able to hear a rattle or vibration.

My Echo died on me this morning and would not restart. I was at a light at the time. I pushed it aside, waited a bit and it restarted. I made it to work and it died again after several hiccups along the way. It then died in my parking spot but would restart. It has 192k miles on it.
It was acting weird earlier this week in that it would lose power (not electricity) while moving and then continue on. It seemed to work if I gave it more throttle. I feel like its fuel related but I don't have a lot of spare money to guess at the problem unsuccessfully.

View 1 RepliesYaris/Scion & Vitz :: 2000 Toyota Echo Drives Fine Until Warmed Up
I have a 2000 Toyota Echo. Symptoms are, the car drives fine until warmed up. Once warmed up, about 10 min or so, there is surging, an inability to maintain idle, periodic loss of brake assist, all consistent with my p1349 code. This happened about two months after I changed my oil (the old oil was in there for an embarrassingly long time). I ran motor flush and again changed the oil; symptoms persist. I have removed the OCV and OCV screen; both look fairly clean. Here's the question: what checks can be done on the OCV itself before I call a bad OCV and replace it? The service manual was of only marginal quality in explaining any checks.
