Signal Too High. Permanent Fault
Signal too high. Permanent fault
Checking components and wiring
Check the resistance of the evaporative emission system (EVAP) valve.
Check the signal cable between control module terminal #A9 (#A9) and evaporative emission system (EVAP) valve terminal 2. Check for a short-circuit to supply voltage.
Hint: Use a test lamp with at least a 3 W bulb to determine whether the cable is short-circuited to supply voltage.
Remedy as necessary.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
