Gas leakage
â–¶ How to fix
- Check the wiring to the tank pressure sensor - Check the pressure and compare with the sensed value - Check the pressure control valve - Check the gas line for leakage - Perform general troubleshooting of high pressure sensor
What you'll see
No driver-visible symptom recorded.
System reaction
- Engine runs and starts bad. - Engine may stop.
Diagnostic depth
Detection
- Gas pressure drops rapidly - ptank_w-dptcngf_w < LLKPNG
Possible cause
- Gasleakage at the CNG high-pressure-system - Possible electrical fault of the tank pressure sensor (i.e. missing supply)
