Passat (B5) :: O2 Sensor Malfunction - Cold Startups
I just replaced two bad sensors, (bank 2, both sensors). I went through three cold start ups, and the autozone codes still claim the sensors are rubbish.
View 1 RepliesGolf IV R32 :: TPS Sensor / TB Malfunction
so I have been getting a 'hiccup' if u want to call it that, with the tps sensor and/or throttle bodie. every so often I like to scan my car for kicks :p and noticed that (not all the time) my g188 or g187 tps leave a code but no CEL. I know I been getting an odd bog like feel when flooring from a stand still or low RPM and have done some reading on it, the tps could be related to that and since I do get a code but no failure I want to see if maybe it's going bad? also since the tb and tps are one unit and $$$ how often do they go bad?
View 2 RepliesGTI 337/20th Anniversary :: 2.0 Low Oil Light Comes On - Sensor Malfunction
So the motor has a new oil pump and pickup and was all cleaned out. Sludge is not the issue here. I'm running the royal purple filter ( the equivalent of mann 950/4) and royal purple 5w30. My heart dropped after the light came on on the first drive. I pulled out over and checked the oil and for leaks and... full with no leak. So I checked the temp and proceeded to drive home. I don't have an oil pressure gauge but I'm getting the bottom of the fill cap with oil so I know it's making it all the way to the top of the motor, and the motor is not loud or sounding starved.
Basically, I wanted a second opinion that it is most likely oil pressure sensor malfunction. Garrett 60 trim, feed and return lines are brand new and sufficient diameter.

I noticed my 2005 GX470 started to "bottom out" when going over speed bumps or potholes. The air suspension seems to work fine raising and lowering ok and the general ride is still quite smooth. From some simple searches on the board it would seem that leaking of the air suspension could be the problem?
I did a code read and got the following error codes none of which sem related to the problem.
Code
CO200 Right front speed sensor malfunction
C1223 Malfunction in ABS control system
C1340 Open circuit in central differential lock signal
C2172 tire pressure, transmitter identification number not registered
Lexus GX 2004-09 :: Auto Windshield Wiper Malfunction - Sensor Going Bad?
My auto windshield wiper function has become real sensitive...When driving in the lightest rain or even mist, my wipers start intermittently, then go faster and faster until they are going steadily, and in medium-light rain, often go to high speed. They never did this in the past, this has recently started. I turn them off, then back on and the process repeats. The auto wiper was always wonderful in the past, but not now.
Is there some kind of adjustment for this problem? Is my windshield sensor going bad?
Jeep - Grandcherokee :: 1994 - Check Engine Light And O2 Sensor Malfunction
So this little gem of an SUV has been good enough to me over the year that I have had it, but it is one of those used vehicles that has me scared to look underneath cause there is always something a miss.
I have been having some power problems and the OBD check engine light has been coming on. The engine like to putter like if it's not getting enough fuel from a clogged fuel filter when it gets going, hot or cold. Have confirmed that the fuel pump is with proper voltage and pressure. Though haven't noticed a big difference with the new filter. The check engine light cycles a code of 21, which is refinanced to the O2 sensor, both upstream and down stream. That tells me that there are TWO O2 sensors for this model. And research has confirmed this. One ahead of the cat and one behind the cat.
Here's the kicker, I only have one O2 sensor at the head of the cat and the location of where the second one would be located is only a solid section of pipe from cat to muffler. I haven't been able to track down the plug connection for the second sensor and these codes and problem only came after I gave the Jeep a tune up.

Corolla / Matrix 2009-13 :: P0500 Code - Vehicle Speed Sensor Malfunction
My car is now 24/7 with this error which is Vehicle Speed Sensor malfunction an there seems to be no way of solving it, symptoms are:
*Speedometer not working, needle always in 0
*Power steering not working
*Car wont past 3rd gear
*Check engine light and power steering light on
I checked all 4 speed sensors and the wiring looks good and they look good. Also if i hit a bump, issue goes away for a couple of minutes, until i hit another, etc, so looks like a wire or short circuit, cant tell. Is there a speed sensor on the transmission as well? where is located?
Sonata I45 (YF - 2011+) :: Code P0705 - Transmission Range Sensor Circuit Malfunction
This is what I get from the DTC .....
DTC P0705
Description : transmission range sensor circuit malfunction
State : History
I have done some google search on the above diagnostic trouble code P0705 and as i understood , it indicates that the Engine Control Module (ECM) has received an input error from the Transmission Range Sensor (TRS).
Since the check engine light illuminated two times (two separate occasion) then it turns off now; the ECM is actually receiving input signal from the TRS.
So that leads me to think that the TRS is actually working but the problem might be one of the following two:
1- Open or short in the TRS circuit?
2- Dirty transmission fluid.
What do you think the steps i should do first of all ? how would i check the transmission fluid since my vehicle has no transmission fluid dipstick. My driving condition would fall into "severe" category and it reached 60,000 miles now ...

CEL/OBDII code P0141 - O2 Sensor Heater Circuit Malfunction
So I just bought this car 64k well maintained but cant get rid of the check engine light. Replaced downstream O2 sensor with no luck. As soon as I get home I'll check voltage @ connector. Lets test the O2 sensor connection and test the pins to make sure there is no break in the wires.
Chevrolet - Lumina :: 1996 - DTC Code P0101 - Mass Airflow Sensor Malfunction
So I have a 1996 Chevy Lumina (3.1L V6 engine) and I keep getting a DTC code P0101, which is a Mass Airflow Sensor malfunction. It's rather annoying because every time this happens, my engine shuts off. I'm talking no power steering, no power breaks, no acceleration, nothing. So I replaced the mass airflow sensor and it continues to stop about every five minutes. However, it does something odd and that is that the car drives just fine when it's in Overdrive and stops when it's in regular drive. I don't know if that's important, but I thought it might diagnose the problem.
View 4 RepliesFord Escape / Hybrid :: 2009 - Tire Pressure Sensor Malfunction Fault
The facts: 2009 4x4 V6 Escape with Valve stem mounted TPMS
I am getting a tire pressure sensor malfunction fault. The warning light is on and the error message is displayed on the little screen in the gauge cluster.
What I have tried: First I should say I have replace to defective sensor twice now...
1) I put the escape in tpms train mode by hitting the hazard switch off/on about 6 times.
2) I used the train tool to train all the tires but there is one that is giving me trouble and will not train.
3) I tried deflating the problem tire and inflating it to the specified pressure given on the be pillar of the escape (30 psig)... after inflating it I tried to retain it with no luck.
4) I tried rotating the tires and as I mentioned earlier I have replaces the problem sensor twice. Still can't can't get the problem tire to train.
My thoughts:
1) I don't think this is a module error because I can train the other tires and since I rotated them I know their position is not a factor.
2) its possible that I have got two defective tpms sensors but I think that is unlikely.
3) I have read of another procedure to put the escape in tpms train mode that requires you to turn the ignition on/off, step on the break pedal, tap your head and rub your belly, etc... but I have not tried this method. Is there a difference from this train mode verse hitting the hazard switch on/off about 6 times?
4) Does the train tool only work on previously trained sensors? do I need to register the new TPMS sensor with the TPMS module? I have an OBDII tool that connects to scanXL software on my laptop which included the ford proprietary protocol. I looked for a way to program a tpms sensor (similar to how I did it with my toyota) but couldn't find the option.
Ford F-150 (2004-2008) :: Rear ABS Center Speed Sensor Input Malfunction
I have an ABS light on. I have crawled under the truck I don't know how many times everything is connected just as it should be. The wires did have to taped up because they burnt into after getting against the exhaust at some point, but I had fixed that awhile ago, I've even tore back into the tape and re-did everything again, nothing gets rid of the ABS light. When this first happened it would go away after I turned the truck off, but would come back after using the brakes a few times, especially harder stops. Then it got to where it just came on and stayed on, and didn't go out no matter what. Thinking my ABS speed sensor went, I bought a brand new motorcraft one from rock auto it fits perfectly in the rear, plug looks good. I can't find NOTHING that would keep this light on. The code is always the same "Rear ABS Center Speed Sensor Input Malfunction", how to get rid of this?

Today I ran into a person I use to work with and was informed he had bought almost the same truck as mine. He also informed me that his has spent most of the winter in the shop. Reason being he claimed the transmission had a sensor that malfunctioned when it's cold out. This sensor lets the truck turn over but it blocks the truck from starting. Now it has got to 10 below zero only once this winter so far, my truck is kept outside, no problem yet.
View 3 RepliesCamry :: 2002 V6 - ( P1135 Code) Air / Fuel Sensor Heater Circuit Response Malfunction
Just got a P1135 Code on the 1MZ-FE 2002 Camry.
My code reader pulls it up as (no typo below) : AirCFuel Sensor Heater Circuit Response Malfunction.
So I know it's a bad Air/Fuel sensor. Which one though? I replaced the rear sensor by the firewall about 6 months ago which fixed the check engine code (I don't remember the code). Would it make sense that the front one failed now or the back one failed again? Most of my research points me to a bad rear sensor however a lot of people also report that a code reader would report the sensor as "Bank 1 Sensor 1".
The rear sensor was replaced with a Denso 234-9042 Sensor.
I would play the replace and test game... however inspection is due within the month and after resetting the code, it usually takes about 50 miles to return. Being in college, 50 miles takes about 2 weeks.
Lexus ES 2007-12 :: Code P0365 - Camshaft Position Sensor Circuit Malfunction On ES350
I have a 2007 ES350 with 90k miles. Purchased in August. I had ignition coil go out and decided to change them all and the spark plugs. When changing cylinder 5's coil and plug, I tried to push the wiring harness out of the way to remove the coil. Result, I moved the wiring harness too far and disconnected the 3 wires (black, yellow and red) that were connected to the cam position sensor connector. (I should've just removed the sensor SMH) I disassembled the connector, got it down the internal pins, soldered the pins to the wires, placed the pins back in the connector and reassembled it with the wires in the order that they appeared to originally be.
Plugged it back in and put everything back in place. Started the car and code P0352 was cleared but replaced with code P0365 Camshaft Position Sensor B - Bank 1 Circuit Malfunction. I'm thinking, either I put that pins back in the wrong order or one of the wires isn't properly soldered in. Either way, I ordered another connector and it should be here tomorrow. I need Either a wiring diagram or a picture of the camshaft position sensor closest to cylinder 5 connected with the wires in the proper order .
Chevrolet - Aveo :: 2008 - Electrical Malfunction - Clock Goes Off - Engine Light On - Fuel Sensor?
My 2008 chevy aveo has electrical problems, I think, sense I purchased it. First off the clock goes on and off randomly and doesn't keep time. Then the engine light is on one day then off the next. Sometimes on hot days sometimes on cold days. took it to Autozone and they have said two different times said there is a something wrong in the fuel sensor ??? took it to the Chevy dealer 3 time, Once they keep it for 3 days and said they couldn't get the engine light to come on.. ei. nothings wrong. the second time they said it was the sparkplugs and they charged me to replace them. 10 minutes after I got the car back the light came back on. The third time, again they said they can't find anything wrong.So the light as been going on one day and off others..I just ignored it...Yesterday, I was in 5th gear and I lost all power. engine still running but now power when I press on the gas. I managed to pull over, turn off the car and it acted fine. It happened again on the way home from work. Now the light is off and it seems fine.
