I got 0120 (throttle peddle communication) and 2135 (???). I assume it was from when the engine got wet during a thunderstorm (hood was up for about 1 minute during a heavy rain). It has been a day and they still will not clear, runs in "reduced power mode". Any suggestions on these?

I can get the 0120 (returns about 3 minutes later) to clear but the 2135 is bugging me.

 

P2135 - throttle/pedal position sensor/switch A/B correlation

I would suggest unplugging the connector at the throttle body and letting it hang off overnight, with the hood closed of course... the connectors are supposidly water tight, water may have gotten in and not be able to get out, if it's just wet hopefully this will give it a chance to dry.

another thing to try is to unplug the throttle body, turn the key on for a few seconds, then turn it off, replug it and then start the truck... maybe that will reset the correlation?

 

Happened to me after a trip to the carwash. Pulled the connector, blew it out with compressed air and it worked fine afterwards.

 

you guys got it. There was moisture in there,...blew it out and no issues. Water tight my ***.
