P1DB6 JEEP Possible Causes
- Check for Powertrain Control Module (PCM) codes
- Faulty Transmission Control Module (TCM)
How do I fix code P1DB6 JEEP?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P1DB6 JEEP code
The cost of diagnosing the P1DB6 JEEP code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1DB6 JEEP Description
The Transmission Control Module (TCM) can detect rationality failures of the input (turbine) speed sensor and output speed sensor signals as well as the wheel speed and engine speed signals received through the Controller Area Network (CAN).
The TCM performs three diagnostic checks that include:
– Multi sensor comparisons of up to three speed signals (input, output and wheel speed).
– Monitoring of the gradient of the input speed signal.
– Double failure monitoring to determine unique failure situations which could require unique limp-in functionality.
