Question about Chevrolet Tahoe
If it is a code P0226 I would not consider it a safety issue. Throttle position (TP) sensor C/accelerator pedal position (APP) sensor ? - range/performance problem Possible Causes: Accelerator cable adjustment, TP/APP sensor Throttle position (TP) switch C/accelerator pedal position (APP) switch ? - range/performance problem Fig. APP sensor mounting
Accelerator cable adjustment, TP/APP switch
This might only be an adjustment issue--make sure the throttle cable isn't so tight that the throttle cannot fully close.
If the cable is OK, it is probably the accelerator position sensor under the pedal.
There are procedures for testing the unit that I will paste below if you care to try them.
If you just want a shop to fix it, the part is about $50 and labor should only be 30 minutes.
Operation The sensor is made up of the two individual sensors within a single housing. Each sensor has a unique functionality to determine pedal position. The APP system along with the Powertrain Control Module (PCM) is used to calculate and control the amount of acceleration and deceleration through fuel injector control.
