P2750Intermediate Shaft Speed Sensor C Circuit Range/Performance

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
  • Needs a drive cycle to confirm a fix
How the car detects it
P2750 says that sensor C produces pulses whose speed is implausible – it disagrees with what the engaged gear and the other shaft speeds predict, jumps too fast or carries noise. No manufacturer documents P2750 publicly. The published checks for neighbouring sensors show what such a test looks like: GM's 2023 dual-clutch TCM compares its clutch 2 sensor with engine speed when the clutch is locked and faults it at 150 rpm difference for 1.1 s, and Ford counts dropouts and noise spikes on sensor B and flags a gear mismatch after 2.5 s. A mechanical cause is just as possible as an electrical one: swarf on a magnetic sensor tip, a cracked reluctor, or slipping clutches that make the ratio comparison fail.
What you may notice
  • Check engine light after driving
  • Erratic shift points or flare between gears
Likely causes
  • LikelyMetal particles on the sensor tip distorting the signal
  • PossibleElectrical interference on the signal lead
  • RareInternal clutch slip making the speeds disagree
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
