Frequently Asked Questions
Q: Will this fix dead pedal on my 2005 Ram 2500 Cummins?
A: Yes! Dead pedal is the most common APPS failure symptom. This direct replacement restores proper throttle signal.
Q: Does this sensor require calibration?
A: On most 1998-2007 models no calibration needed. Some 2003-2007 may benefit from APPS reset (key-on, pedal sweep, key-off).
Q: How can I confirm my TPS is bad?
A: Check for codes P0121-P0124 or P0221-P0229 with OBD2 scanner. Test with multimeter voltage should sweep smoothly 0.5V to 4.5V.
