Limp Mode after puddle
Hey all. First post here (unfortunately under bad circumstances). Got limp mode after rain. Went through a big puddle last night and went into limp mode with traction control light on Car shut off but turned back on after when cranking. Throwing P2135. I let it dry overnight but code still came back after i hit 40mph. I’m gonna try electrical contact cleaner on the throttle body connector. Any other things I should try before taking it to the shop next wednesday?

As a new member it is ALWAYS a good idea to tell us the model year as a minimum when asking for help…can be a bad TPS sensor or wiring issue…if you don’t have either a DMM or a scan tool to be able to look at the 2 TPS sensor potentiometers let your shop diagnose it…best to check with a scan tool or labscope…there is a disagreement between the 2 sensors…most likely your shop will just replace parts.
