- Misfire
- Misfire
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly

Possible Causes :
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

Common Misdiagnoses
- Vehicle Speed Output Circuit Problem

Repair Processes :
Pack the connector cavity with dielectric silicone compound (same stuff they use for light bulb sockets and spark plug wires) and reassemble.
Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness.
