I have multiple readings p0320, p2106, p0446. I've read several posts on each of these codes, they seem to be completely different issues, I'm wondering if anyone can clue me in on whether or not my assumptions are correct or if this is all pointing to one problem.

 

P0320 - Ignition Engine Speed Input Circuit Malfunction
P0446 - Evaporative Emission Control System Vent Control Circuit Malfunction
P2106 - Electronic Throttle Control (ETC) Throttle Position (TP) Sensor, Throttle Control Motor

From what I've read, the P0320 could effect the P2106, so you should remedy the P0320 first. For the P0446 I'd start by making sure the fuel cap is on correctly and securely.

Hard for me to see a connection, from what I know. Have you reset the PCM to see if the same codes return?

Are you using a moderate/high power radio transmitter in the vehicle?

 

I had random Ghost codes for a while, tracked it down to the harness connector on the driver side of engine, opened connector sprayed with WD40 and no codes for 2yrs...
