I've been dealing with this code off and on for nearly two years. I've changed TPS Sensor several times, changed MAF sensor, cleaned Throttle Body, replaced TPS Sensor pigtail (broken clip), Reprogrammed ECM at dealership. Changed TPS Sensor two weeks ago (AC Delco) and followed the Technical Service Bulletin to the letter. Last night experienced "Reduced Engine Power, Stabilitrack Off, and Code P2135. Most people seem to replace the TPS Sensor and never have another problem. Any suggestions?

Welcome to AF, no mention of year and engine. Anyway if this is drive by wire, there a tps on the accelerator pedal and the throttle body.
