C0335 Stearns Knight B code definition:
C0335 is a kind of OBD-II Diagnostic C-Chassis Diagnostic Trouble Code for Stearns Knight B.

Symptoms
Symptoms of a C0335 Stearns Knight B diagnostic trouble code may include:
- Faulty or damaged wiring
- 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
- Poor fuel economy
- If the DPF is not cleared the ECU will revert to the "Limp Home Mode" until the situation is corrected
|
Possible Causes :
- A large air leak at or near the number one oxygen sensor would also cause a lean mixture.
- Faulty IMRC actuator relay (if equipped)
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

- Low Coolant Circuit Problem
- Cruise Control System - Vehicle Accel Too High Problem
- TFP Valve Position Switch-Drive Without Drive Ratio Problem
- Problem
Repair Processes :
Use the DVOM to test resistance and continuity on all system circuits if actuator and sensor resistance levels are in compliance with manufacturer's specifications.
With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
Look at the plug wires to make sure they are not burnt or laying on the exhaust.
