P2751Intermediate Shaft Speed Sensor C Circuit No Signal
- 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
- P2751 is reserved for a sensor C that sends no pulses at all while the vehicle is demonstrably under way. No manufacturer documents P2751 publicly. For comparison, Ford's intermediate shaft logic treats a reading below 250 rpm as missing – for 2.5 s on the 2024 ten-speeds, for 5 s on the 2012 transmissions – and it only runs once turbine and output speeds prove that the gearbox is turning. Unlike the circuit code P2749, nothing has to be electrically wrong: a sensor whose electronics have quit, or a toothed wheel that has shifted away from the sensor face, also ends in silence. Expect the module to switch to a substitute speed or a limp-home gear, and confirm on a test drive with the scan tool showing sensor C.
- What you may notice
- Warning lamp during the drive
- Limp-home gear or missing shifts
- Likely causes
- LikelySensor C electronics failed
- PossibleOpen circuit or disconnected plug
- RareReluctor missing, loose or too far from the sensor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
