which is your engine code exactly?

The vacuum regulator.

I'm not sure what code it is. My fiance took it to an Autozone months ago when the warning light came on and she said that guy in autozone said the code was for the EGR Valve.

Regarding the Voltage Regulator, it is the one that has a connector with 2 pins right? Because when I disconnected it, the car wouldn't come on.

Yes, it's the one with 2 pins.
I'm really surprised that the car doesn't start because of that. It doesn't make sense. Normally when you disconnect it, it should closes and disable EGR... anyway.

Ok well then I had the right one and it won't start when I disconnect it. Do you think the EGR Valve faulty.

No, cause if it was the EGR valve, it will not start at cold and hot condition.
Your only stall at hot condition. It something electronic.

Ok I understand. The EVR is activated with ground, not 12V.
Disconnect is again, but connect the signal pin to Ground. (Not the pin on the connector, the one on the regulator solenoid).
And connect the other pin on the battery.

Polarity doesn't matter on a solenoid.

I'm going to try it tomorrow. I'll let you know what happens. Thanks again.

Well I think I may have mistaken the TPS sensor for thr DPFE sensor. When I said I tested the DPFE sensor, I believe I tested the TPS which is mounted on the front of the throttle body I believe.

Throttle position has 3 pins also and it's a very small black device connected to the intake with the throttle body. So yes, you mistaken it.

So now you will test the DPFE sensor. It's rectangular metallic/black device with 3 pins connector and 2 pressure hose.

Test voltage while engine is cold and hot. Also when engine stall, see if voltage is too low.

If I can gamble on your problem, I bet on the DPFE sensor.

I took it to a dealership and they said I have a shorted CAM Sensor and synchronizer. Is this something I can fix?

serge_saati · 12-10-2009, 11:17 AM

Yes you can fix it. Just replace the cam sensor or try to repair the short circuit if possible. Then replace synchronizer shaft of cam shaft.

Look in your service manual in chapter 6 "Emission and control engine systems".
Then go in section of Camshaft position sensor. They explain how to replace it and give a schematic for the synchroniser.

It has 2 sections for the CMP sensor, check the 2nd one for the replacement..

userpete1037 · 12-25-2009, 06:42 PM

Sorry for the late reply but the CAM sensor was bad and the egr valve was bad. Everything is fixed now. Thanks for all the help.
