Code 34 Update

fost9508 · Nov 20, 2004

I keep getting code 34- EGR out of range..etc....

So I have done the following...

1) Applied vacuum to the valve with my vac pump. It opens and kills the car, expected. Good.

2) I go to the solenoid valve and don't get any readings from it when I probe the wires. I ground the circuit and the valve passes vacuum to the valve and the car dies.

I don't know what this means, but apprently the valve works, it just isn't getting the signal....at least this is what I think.

What is the next step???? Non of my books discuss what else to do

Thanks again

one thing to check is that the EGR valve seat is not worn. basically the sensor will read incorrectly if the seat has worn. so it tosses a code.

good luck bud - sounds like you are picking them up and knocking them down.

Unhook the connector from the solenoid and hook a voltmeter to both wires. Rev the engine up and see if you get a reading. If there is no reading, then the ground is not being supplied. Do the same thing I told you to do in the other post about the other solenoids.

If you do get a reading, hook the connector back up, put a vacuum gauge on the solenoid and rev the motor to 2K. You should get a reading on the vacuum gauge. If you do than you got a problem with the egr sensor or egr valve.
