The harness in that area around the AC compressor is susceptible to corrosion at the splice points. Clean it up with some brake cleaner, and carefully, with the engine running wiggle it around with your hand and see if you can get the engine to stall or miss. Or, you might just need a new crankshaft position sensor. The Grey and Dark Blue wires off the crank position sensor just go straight up to the PCM plug (pins 30 & 41 middle plug).

Thanks for all that.

I already replaced the sensor, wiring all looks good and didn't notice a change when moving the wires with the engine running. The wires to the connector for the sensor look like they feed into a larger loom that also contains the wiring for the starter, I guess I'll have to take that apart next.

Did you do a continuity test on the the two wires from the sensor to the pcm?

The continuity test passed. What would you do next?

Could my P0320 be caused by any of the speed sensors on the transmission?

NO


Is the area of the crankshaft position sensor and plug covered in dirt and grime ? Hopefully you gave the plug a good spray cleaning with contact cleaner or brake cleaner.

I cleaned the connection with electronics cleaner. The sensor grounds to the timing cover right? I guess I’ll take it out and clean the surface.

Check the pdf package I sent you. It has a ground diagram and location.
