12 - CLT sensor error

Scroll Prev Top Next More

Throttle sensor, open or shorted.


Note: When this error code is in the system, the engine fan output is activated as a security feature.




Most common issues and how to fix them



1. Check the wiring


Check wiring. All CLT sensors are two wired, one pin to Sensor GND (CMC1: H1) and the other to CLT (CMC1: F1) analog input of MaxxECU.



2. Make sure sensor is wired to Sensor GND, and not engine ground.


3. Check analog inputs (raw voltage)


Without no sensor connected, the CL input voltage should be ~5v.
