Natural gas rail temperature sensor
â–¶ How to fix
- Check natural gas temperature sensor - Check plug connection natural gas temperature sensor and EGC4 - Renew combined natural gas temperature sensor - For LNG: Check heat exchanger at the tank
What you'll see
No driver-visible symptom recorded.
System reaction
- A replacement value is used instead of the sensor value. - This may decrease the performance of the engine. - Vehicle starts badly or doesnt start at all. - Engine runs badly.
Diagnostic depth
Detection
- Natural gas rail temperature sesnor signal below threshold - wtng_w < UADCTNGMN
Possible cause
- Natural gas rail temperature sensor defect - Natural gas rail temperature sensor short circuit to ground - For LNG: Heat exchanger at the tank is broken or malfunction
