P0C1D
Electric/Auxiliary Transmission Fluid Pump Control Module Internal Temperature Sensor Circuit Range/Performance
What it means
The internal temperature sensor signal is outside the calibrated range. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Is it safe to drive?
This code can put the vehicle into limp or reduced-power mode. Avoid extended driving and have the vehicle diagnosed promptly.
Most likely causes
Sensor characteristic drifted
highOne of the most commonly reported causes for this code — check this first.
Thermal lag in module package
mediumA plausible cause — test and verify before replacing parts.
Sensor element aged beyond calibration window
lowLess common, but worth ruling out after the more likely causes.
