P0336 - CKP Range Performance ---> Chevy Venture 2000

Check Engine light on. Car generally starts up kind of good and rarely when being at low speed it stalls and it's pretty difficult to start it back up.

Already REPLACED 7x CKP sensor located at the back of engine and its harness which turned out to be pretty damaged, afterwards engine starting got slightly better.

Also REPLACED 24x CKP (3 wire sensor) at the back of the harmonic balancer which was extremely damaged too. The cables were entangled, rusted and covered up with dirt.

However the problem is still there and the light is on, car stalling a little. I pulled the code and in Frezze Frame it shows up that the P0336 is taking place at low RPM's (between 696-720 rpm's)

Spark Cables have been checked and they are good.


Please advice.
Thanks in advance

OK, after going through the whole troubleshooting procedure I was able to find on the Internet (the one I described on the first post) , I finally got rid of the Check Engine light after replacing the CRANK PULLEY along with the Harmonic Balancer embedded onto it, I guess it was something related to the AIRGAP that was being affected by the slightly wobbling pulley.

Wish I would of seen this earlier I could of helped. The 24x signal is used at low rpm up to around 1600 to help with idle quality and low rpm misfires then above that the 3x sensor takes over. Balancers are a common problem and tend to seperate and cause lots of problems.
