Ford F-150 (2004-2008) :: 2005 XLT - P0453 Code / Locating The Sensor
I just acquired a wonderful 2005 F-150 XLT 4.6 liter truck. I need to get it passable for smog check here in AZ and the failed test revealed a P0453 error code (EVAP) which translates to a possible pressure sensor malfunction.
My question is finding the sensor and if I am looking at dropping the fuel tank to service/replace the sensor. Also, could a vacuum line be the cause?
Ford F-150 (2004-2008) :: 2007 F150 Sputtering After Fill Up - Fuel Tank Pressure Sensor
The ole 5.4l hit a snag today. I was on my way to fill her up and she started sputtering and damn near died! i filled her up and it was like nothing ever happened. Took her to AutoZone and the diagnosis was a Fuel Tank Pressure Sensor.
I have a connection with Bumper-to-Bumper to get the part for cheap but I'm not sure if i want to dive into either moving the bed or dropping the tank. I'd prefer to move the bed.
Sierra :: 2003 - No Fuel Pressure At Cold Start
I have an 03 Sierra Half Ton when the engine is warm it runs fine but at cold start, half the time it doesn't have the fuel pressure to start, i have to turn the key a couple times to build it up. Idk if the fuel pump is weak for if it would be more the regulator. I started having this problem after i replaced the fuel pump. The fuel pressure gauge shows 50-55 lbs, but every now and then when its cold it will only jump to around 5 lbs (but this is only when the engine is cold... why?) What should i go after first? Regulator, new pump, Replace the fuel filter again?
View 2 RepliesFord F-150 (2004-2008) :: P0453 Code After Broken Ground Wire
My 2007 F150 5.4L would not crank at all the other morning. After checking the battery, I discovered that the ground wire to the starter was completely frayed and broken off right at the eyelet connector to the starter. I spliced it back together and the truck fired right up.
However, the check engine light suddenly appeared and I got a P0453 code which apparently indicates a high reading at the fuel pressure sensor. The CEL never appeared until the broken wire happened. I took a quick look at the fuel pressure sensor and wiring and nothing appears to be obviously broken.
One other thing I've noticed for a few weeks is a miss under load while driving. I have not seen any codes at all for the miss. I was leaning toward replacing the coil overs but now I'm wondering if the miss is related to the fuel pressure sensor.

Lexus RX 2010-15 :: 450H Fuel Tank Capacity And Tire Pressure
The manual for the 450H does not agree with what I am experiencing.
1. The Manual says the fuel capacity is 17 gal, but with an empty tank the most I can put the tank is around 14 gallons. What is the real capacity, and why does the manual say 1y7 gallons.
2. For my 450H with 19 inch wheels the manual says tire pressure should be 33 psi. However, when delivered from the factory the tire were 39 psi. What should the tire capacity be?
There seems to examples throughout the manual of conflicting information.
Lumina :: 1995 Chevy - Excessive Fuel Tank Pressure / Slight Hissing Periodically
1995 Chevy Lumina 3.1L Sedan with ~182K mi
Over the past 6 months, I have noticed fuel odor just about any time I turn off the vehicle, and I am also experiencing progressively higher levels of fuel tank pressure each time I remove the fuel cap. The fuel tank pressure seems to be greater the lower the level of fuel in the tank whenever I remove the cap. 6 months ago (~Sept) it was only a slight "hissing" periodically when removing the cap to fuel up, but now it occurs at every fill up and seems to have enough pressure to push the cap entirely off had I not been careful to slowly loosen the cap to relieve the pressure.
The entire fuel pump and sending unit assembly in addition to the tank and filter were all replaced about 4 years ago in May 2010 or about 28K mi ago. The issue has just come up progressively over the last 6 months.
Today, I inspected the evap. emission components and lines from the tank to the canister to the purge solenoid mounted on the rear of the engine. All lines are connected and seem to be in operable condition. The line from the canister to the purge valve mounted on the engine is completely free with no obstructions. I blew out the line with compressed air and absolutely no exiting particulates were observed. The lines on the bottom of the canister did not show any signs of wet fuel and there were no carbon particles present in the lines from what I could tell from disconnecting and inspecting. The vapor line from the tank to the carbon canister is not kinked or pinched in any manner.
I believe there is a fuel vapor check valve that resides inside the tank connected to the fuel pump assembly/sending unit. This was all replaced as a single unit as mentioned above. I am thinking this check valve may not be functioning properly and not allowing the vapor to escape into the carbon canister. I tried to apply slight pressure and vacuum on the vapor line connected to the check valve on the tank but no air was able to move in or out even with the gas cap off. However, I do have a full tank of gas right now, so I imagine the check valve will be closed.
The check engine light is not on but since this is an OBDI vehicle I am not sure there are any evap. emission codes anyway.
How can I test the gas tank vapor check valve? How can I test the vapor purge solenoid located on the rear of the engine? What malfunctioning component could be causing the excessive fuel tank pressure.
Grand Prix :: 2000 GTP No Pressure In Fuel Line - Click Or Clunk Noise In Gas Tank
It is the 2000 GTP 2 door. It is my sons car and is dead in front of my house. Changed the fuel filter as it is cheap to do. At the check valve there is no pressure in the fuel line. I turned it over with the hose off the filter it did not pump any fuel. I do hear a click or clunk in the gas tank when I turn it over suggesting it is getting power into the pump.
I almost went and bought a pump but do not really want to put the $230 + tax down without checking the resistor after reading around the net.
Grand Prix :: 1997 GT Running Extremely Rich And Pressure Build Up In Fuel Tank
I'm having this weird problem with my car, 90% of the time it will start to run rich, until it reaches normal temp, to the point that I can smell it coming out from the exhaust. LTFT is at around -15% and it seems to go down after cruising for some time but will go back to negative at idle. My first suspect was the FPR so I checked it and found no gas smell on the vacuum hose, then I decided to run the engine with the vacuum hose disconnected and see if any fuel would come out, 5 minutes later and it was still dry.
There is a chance that the MAF sensor is bad, I'm 90% sure it is, because it will sometimes read 2.9-3.1 gps at idle and according to the rule of thumb of 1gps per liter of displacement, it shouldn't go that low but I might be wrong about it; I disconnected the MAF and the smell was still there, today while driving it was reading 5.45gps (A/C was on) and the smell was still present; car also feels sluggish from time to time only at normal operating temperature (which I assume is because of it running rich).
There is also a vibration felt through the steering wheel only while idling in gear at all temps. Today when I got home and after I turned off the engine I heard a noise like water was running. It was coming from the car so I tried to find where the noise was coming from and it's from the fuel tank. I removed the fuel cap and lots of air came out (or sucked in?). I reinstalled the cap and pressure started to build up almost immediately! I have a video, which I'm sharing, so you can see what I'm talking about; I was even able to hear the fuel tank expanding because of the pressure inside, not sure if you can hear it towards the end of the video (when I put the phone under the car). [URL] .....
It also happened today that I was cruising and the engine hit the rev limiter after I stepped on the gas (WOT) to overtake another car. I immediately removed the foot from the pedal and gave it less gas and it acted normal, no slipping from the transmission at any other time. There is one more thing that I'm not sure about it. Every morning, the engine will sputter for 1 or 2 seconds after starting it but it will be fine for the rest of the day. I once tried disconnecting different sensors from the engine and the only one that seemed to make a difference (it didn't sputter) was the TPS.
Things done so far:
- I replaced the EVAP purge solenoid (P0441 was present) back in february.
- Rubber pieces at charcoal canister also replaced, old ones were rotted to the point my hands would look black just by rubbing against the hoses.
- Upper intake manifold was also replaced by me in november last year.
- New NGK spark plugs and OEM spark plug wires last december.
- Cleaned the MAF sensor with MAF cleaner, no dice. Used brake clean, no change. It's a reman Cardone from autozone, which tells us it's 90% sure it's broken.
- New Duralast MAP sensor back in 2010 because a mechanic broke the original.
- 10qts transmission fluid and filter replacement 2 weeks ago.
- Fuel pump was also replaced back in 2009 maybe, can't remember the exact year. The old one would start making some kind of a hissing noise after prolonged driving.
NO DTC'S PRESENT. I once checked Mode $06 data with a mid-level scanner I have (AutoXray EZ-scan 6000) and saw a test had failed, I think it said something about the MAF and EGR. IHaven't connected my fuel pressure gauge tester. Since I can smell it running rich, I didn't think it would be necessary. I'm thinking that there could be a problem with the EVAP system that's causing the excessive pressure in the tank but I'm not sure what that could be. Is there any chance that the pressure is also causing the rich mixture?

View 2 RepliesSilverado :: Getting Code P0523 - Engine Oil Pressure Sensor?
When my check engine light came on I hooked up the tool to see what code I would get. This is the code I'm getting which indicates a problem with the engine oil pressure sensor/switch circuit high voltage.
Question 1: is this a simple fix and about how much do you think this would cost at a Jiffy Lube or Walmart type place?I'm also concerned because the MIL is no longer on. I'm wondering if I could have cleared it off using the tool. This morning the engine light was no longer lit and my oil pressure guage is reading no pressure at all now.
Question 2: could it be possible to have no pressure? or like the code indicates it's just a matter of the sensor not reading the pressure?
Question 3: is it safe to operate the vehicle? I'm not going to have any money in my budget for at least another month.

View 1 RepliesFord Ranger / B-Series :: Changing MAF Sensor / High Fuel Pressure
I have a 2009 Ranger 2.3 L manual with about 100000 miles. The engine was bogging down and I just found out that the MAF sensor is bad from testing it. In the process, I measured my fuel pressure to be 73 psi (manual says 60-65 psi). So I have two questions:
a.) Is there any chance of just cleaning the MAF sensor. The sensor has zero volts when running and warm (or .02 v) and barely changes when reving the throttle.
b.) Perhaps then the high fuel pressure is an unrelated issue. Is this so high that I must change the regulator as I have to change the pump as well? Might it be some other issue than the regulator which is what the Hayness manual says?
One theory I had for the high fuel pressure is that the bad MAF was leading to bogging and lean conditions and the computer was running the pump more to compensate but I think the computer might run the pump based on fuel pressure not the o2 sensor.

A few days ago code 0496 popped up for evap system problems. The fuel tank is very pressurized and there is a constant bubbling heard in the fuel in the tank with the gas cap removed. Sounds like blowing air through a drink with a straw. I have never had a problem like this with any car in over 45 years.
View 1 RepliesFord - Explorer :: 1995 - Replaced Fuel Pump / Filter / Pressure Regulator / Crank Position Sensor But Won't Start?
1995 Ford Explorer, 4 ltr. engine, pushrod. Will not start. Replaced fuel pump, fuel filter, every relay, pressure regulator, and the crank position sensor. I realize there's a whole bunch more parts under the hood, but I am ready to give up. Before the fuel pump would not run. Reason for replacing the parts. Now it won't stop running and you can feel the fuel by-passing at the pressure regulator. When checking the pressure at the rail I get zero !! I used a tire pressure tester for this. And, like I said no pressure. This vehicle has around 170,000 miles on it.
