Sounds like you need to get the pressure sensor checked out.
If that is the problem, once it is replaced you would have the code cleared and the check engine light should stay off.

SOURCE: Coolant Temp Sensor

The sensor is located on the drivers side engine block...although you can see if from looking from the top of the engine, you would have to get under the vehicle and look up to replace it. Be aware that it takes a special tool to unscrew the old one and screw in the replacement.

SOURCE: Check engine light came on my 2002 Rav 4. Auto

Chances are, it's going to be either 1 of the 3 switches that need replacing, a new gas cap or a new charcoal canister. The 2 switches under the hood are the VSV for CCV and VSV for EVAP. The one at the canister itself is the VSV for VSP. This VSV for VSP typically goes bad before the other 2 switches do. Plus, the switches are much cheaper than a new canister. (BTW, VSV stands for vehicle switching valve.)

PO446 is an evap canister code

Jeep Liberty 2002 woahs !
by porth21 - 2/1/09 7:35 AM In reply to: Jeep Liberty 2002 speedometer not working by Dannywon
I have a 2002 Jeep Liberty Limited with the same problem. The main problem I have found to be the routing of the speed sensor wires located on the rear difrential. They are 2 blue wires on my jeep and probably the same on yours. The problem is that they rub on the E-brake cable and once the wire is exposed they short and the speedometer and any other options running off they speed sensor quit working and that includes the tranny shift points and can cause the torque converter to not unlock and cause stalls. I am having the same problem for the third time and chrysler and jeep are both aware of the problem and unwilling to repair the problem or post a recall.

Where is the fuel pressure sensor located on a 2002 GMC Sierra 1500 4X4?


The fuel tank pressure sensor on a 1999 GMC Sierra is located on the top of the fuel tank on the fuel pump itself. Most say that you need to drop the fuel tank to replace it but if you have access to a lift you can replace it without removing the fuel tank. By removing the rear U joint straps and moving the driveshaft to the side you can see and access the sensor for replacement. Chock wheels to prevent movement of the vehicle after driveshaft is disconnected.

I have a 2002 GMC Sierra 1500. 4.3 liter engine. I brought it to autozone and they put the gauge on it and got two codes P0140 and P0300. I had my distributor cap replaced, ignition rotor, plugs ,wires,...


Clean mass air flow sensor with a nonchlronated brake cleaner,install new air filter and check all vacuum lines for leaks then check for vacuum leak around or at intake manifold.Code P0140 is for mass air flow sensor code P0300 is a multiple misfire which more than likely is a vacuum leak possibly intake manifold gaskets leaking.

CHECK ENGINE LIGHT STAYS ON. WAS TOLD IT WAS THE 02 SENSOR/VALVE. WHERE DO I FIND THIS? GMC SIERRA 1500


You should have 5, O2 sensors on your Sirera. What are the DTC codes, each codes will indicate which O2 sensor needs to be addressed, or is this an answer with someone guess what the check engine light is saying.
Thye check engine light could be from a bad O2 sensor to just a bad or loose gas cap to a transmission issues.
Thank you for using fixya and note that Auto Zone and most larger auto parts store will scan DTC codes free of charge.

I just replaced the battery in my 2000 gmc seirra. The truck cranks right up and will run fine for a minute or two. Then my battery acks like it is going to die, but if I shift it into park everything goes...


Did you make she that the battery has the right cold cranking amps, or the alternator? some times on an alternator the selfegnighter might have gone bad. Also sounds like there might be a wiring or fuel injection problem. Is there a check engine light on? Start simple, put some sea foam in the gas tank (you can get sea foam at auto zone for 10.00) that might cure the rough idle.

Could be a wiring issue, fuel cap got left off, fuel pressure sensor again or loose connection to the sensor and one of the other Evap hoses. Also might try changing the fuel cap. Look at the underside of the fuel cap and if there are cracks in the sealing rubber, replace the cap.

O2 sensor problem


I have a 97 gmc sierra .This truck is the same as the chevy ok.Its a 350 5.7 liter 4x4 Z71.I took it to auto zone which was my first mistake.They put it the scanner and said bad O2 sensor.Ok so which one is it i said.They dont know.Well there four (4) O2 sensors in this truck i hope you know that.I had to replace all four of them before i had to take it to a real shop.It seems the fuel pump i replaced a week earlier with an auto zone fuel pump was bad.Ive changed my feul pump 4 times now and have 235000 miles on still running.You need to get your fuel pressure checked.It should be 65 psi to start it and 55 psi to run it.If the pressures are good it could be a different O2 sensor or maybe the mass air flow senor.My last option would be the fuel pressure regulator because it seems to be a waste of time and money.I would get that fuel pressue checked first.Good luck.
