Check this out, I had a code 34 for the egr valve I replaced the egr valve and sensor, reset the timing and also released the code for the egr valve by disconnecting the main lead. My timing was off and I had it reset every time it is reset it ends up changing itself. How does this happen and why? Also what is a knock sensor and what purpose does it serve.
have the same problem?
