1. Using a scanner, turn the Key On Engine Off (KOEO).

2. Check for a baro reading from the AIR pressure sensor of about 100 kPa (or 14.7 PSI)

3. Start the engine, turn on the air pump and the AIR control solenoid valve. This will measure the pressure from the air moving through the system into the exhaust. Expect to see 8-10 kPa higher than the KOEO kPa reading (or 1.16 to 1.45 PSI higher than KOEO PSI reading).

4. With the engine running, turn on the air pump, but shut off the AIR control solenoid valve. (This is basically a dead head test of the air pump). Expect to see 15 to 22 kPa above the KOEO baro reading (or 2.18 to 3.20 PSI above the KOEO PSI reading).

SOURCE: 2004 pontiac grand am service engine soon light

I have the same car and if the gas cap is loos for any reason the service engine light will come on so check that. If it is it will turn off in a few days after you tighten it.

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

SOURCE: Hi, I need to know the location of the PCV valve

It is located, as you are standing, facing the front of the engine, on the left front side going into the valve cover.

It is a little silver part that rattles when you shake it.


Good Luck...

2004 PONTIAC GRAND PIX STALLS WILL NOT START BACK UP SOMETIMES STARTS AND RUNS GREAT THEN WILL JUST STALL WILL NOT START FRO DAYS


Fuel filter, fuel pump, fuel pressure regulator, Idle air control valve, mass air flow sensor, faulty plugs, faulty injectors. If there is any codes set that is where I would start. The check engine light code is going to tell you somewhat what is going on. There are too many different things that there can be. My guess is mass air flow sensor or something with the fuel.

Here is the definition of the code and possible causes.

P0449 PONTIAC Description The Engine Control Module (ECM) monitors the Evaporative Emission System (EVAP) Vent Valve/Solenoid system wiring for opens or shorts.

When is the code detected?The Engine Control Module (ECM) has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Possible causes - Vacuum leaks, damaged hoses or improper routing
- EVAP system - Check fuel cap, canister, valves or components

2004 Grand Prix GT gas cap light,an engine light is on. Took it to autozone an code read po445 replaced gas cap, an light is still on. is there a time limit on light going out if i jus replaced it? Or what...


P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted is located in the engine compartment and is most likely the root of the problem.Would check the plug and wiring going to this to verify that no plug or wiring damaged has occurred.It is quite possible the part has gone bad.

Hello... My name is Marcy... I have had my 2004 Grand Am in and out of the shop since 5/24/10... First the code read for the egr Valve replace egr Valve scan service exhaust port and remove and replace egr...


Hi Marcy,

I have a 2003 Grand Am GT with 185K on it currently. I have had the intake manifold gasket replaced, the cylinder heads done last year and now my SES light comes on now and then, had it scanned and the P1404 fault code comes up..they tell me it related to the EGR valve. Luckily, I work at a car dealership, but my car hesistates to get speed going on the highway, the RPM's will be up to like 3 and I'll be doing 35mph. I thought it was the transmission starting to go, but hopefully not. Anyway, I feel your pain, they did guess work last year and was replacing parts I didn't need only to find it was the cylinder heads leaking. I didn't have the usual symptoms of white smoke, etc. Anyways, I would recommend calling Pontiac and tell the dealer to cut the **** and fix the damn car. That's what I did and they were hot on the case involving the general manager of the store. They ended up giving me a huge goodwill because I told Pontiac that they were just putting parts in my car, charging me and not fixing the issue. I got a free rental and everything. I was going to report them to the Attorney General. I hope you find the issue with your vehicle, I just paid my off literally last week after a 5 year loan and I want to have this car for a couple of more years seeing as I just put so much $$$ into it.

Let me know how you make out.

All the best.

1999 plynouth grand voyager was coding egr replace


just because the check engine light is back on, it doesn't necessarily mean it is for the same problem. it could be, but would need to pull codes again to find out what its for. literally hundreds of different codes could turn on check engine light. also, was original code for "insufficient egr flow" or "excessive egr flow"? it makes a difference.

Engine service light


The DPFE (Diferential Pressure Sensor)sensor is usually mounted on the engine and is connected to the pipe that runs from the exhaust manifold to the EGR valve with two rubber hoses. When the sensor goes bad, the Check Engine light comes on and typically sets any or all of teh following fault codes: P0171 & P0174 (lean codes), and/or P0401 (insufficient EGR flow). Nine out of ten times, the fault is not a bad EGR valve or a vacuum leak, but a bad DPFE sensor. A replacement costs about $112 at Ford, or about $48 at an aftermarket auto parts store.I hope this helps.
