Monitor description.
Inferred mixture strength (lambda) above threshold, (leaner mixture). Monitors cylinder specific fuelling errors which may not be detected by the overall fuel system monitor
- Fuel injector connector is disconnected, connector pin is backed out, connector pin corrosion
- Specified cylinder, localized air leak on intake manifold to cylinder head connection
- External fuel leak at fuel injector
- Fuel restriction within fuel injector
- Specified cylinder, localized damage/restriction of fuel rail
- Air leak around spark plug
- Air leak around fuel injector
- Fuel injector failure
- Ignition coil failure
