My check engine light goes on intermittently, I has the codes read when check engine light was on at Autozone and received P0325 (knock sensor) and P0073 (Ambient Air Temp) I am having trouble finding info on the location of the knock sensor, and the control module. I removed the air tube between the air filter and intake manifold and put an ohm meter on the air sensor at the intake and blew on the sensor and saw the resistance change.
Does anyone know where I can find the knock sensor and info on the control module that monitors these sensors ?

Thank you

 

Knock sensor is just right of the oil filter. The "control module" sounds like the Powertrain Control Module better known as the PCM. It's mounted forward in the driver's wheel well behind the splash shield. It needs to be programmed to the van either by an aftermarket vendor or your dealership. $150 - $500. First step? Clear the codes and see what returns.

Thank you Raptor, The problem has snowballed. Before seeing your reply I disconnected the battery to clear the codes and started looking for anything obvious, bad connections and such, after re-connecting the battery and trying to start the car, I now have a new code p0688 (Automatic shut down ) I did find a wire crimped under the fuse box/ power distribution module. I plan on doing a lot of continuity testing tomorrow and hopefully clear the P0688. So far this video looks like it will be very helpful to me tomorrow. So far I haven't had any luck finding a wiring diagram.


Your information was excellent and if I can get it to start again I will check that knock sensor.
Thank you again, I let you know if I have any progress.

 

Raptor, TYVM for your help, after purchasing a subscription to alldata I had the diagrams necessary to troubleshoot flaky wiring between the IPM and the PCM, thanks again for your help
