Code p 2176 refers to both the accelerator position sensor E and the throttle position sensor E--maximum stop performance ===causes --wiring---APP or TP sensor code p 2135 refers to same items but switchF A/B- voltage correlation or implausable signal===causes --same as previous I have no listing for a p 1516 as the book does not cover it but I am guessing that it is a specific code to hummer and still related to the problem area of the APP or TP units if you find and fix the APP or TP problems then that code by go
