Showing items 1 - 3 of 3 results.
thanks for the info- problem was in the computer controlled regulator- the evaporator was partially plugged and the diaphragms and valve were also dirty-cleaned out and replaced bad parts runs like a dream now
106-4, indicates map sensor fault.
However the following can also cause map sensor issues.
522655-0 PROCEDURE OR ACTION:
1. Common problems that may cause rich codes:
* Clogged/dirty air filter
* Fuel quality (Very high butane content)
* Operation at high altitudes
* High primary fuel pressure (for trim fuel injector)
* Faulty trim fuel injector or wiring
* Faulty LPG carburetor (power valve stuck open)
* Faulty LPG regulator
* Manifold vacuum leaks
* Improper ECU grounds on engine block
* Faulty ECU injector driver 2
2. If DTC continues to be displayed after examining/correcting the above
the 52265.5-0 is not correct 522655-0 for vortec v6 ???
