C0315 American Wayferer Diagnostic Trouble Code
C0315 American Wayferer code definition:
C0315 is a kind of OBD-II Diagnostic C-Chassis Diagnostic Trouble Code for American Wayferer.
C0315 American Wayferer is defined as Cylinder 3 Injector Circuit Malfunction. This code means the PCM (powertrain control module, also known as ECM or engine control) has detected a problem in the injector or its wiring, or in injector circuit for cylinder 3. As you drive and when specific conditions are slowly met, the vapors will gradually purge from the charcoal canister and will get burned within your engine.
Symptoms
Symptoms of a C0315 American Wayferer diagnostic trouble code may include:
- Faulty O2 Sensor
- Lack of power
- If the DPF is not cleared the ECU will revert to the "Limp Home Mode" until the situation is corrected
- 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 :
- Defective ECU strategies or components will prevent proper regeneration
- The Mass Airflow sensor is a hot wire that senses the volume of air entering the intake manifold. The computer uses this information to control fuel mixture.
- Fuel with a large percentage of sulfur will clog the DPF quickly
|
Common Misdiagnoses
- IC Circuit High Voltage Problem
- Control Module Throttle Actuator Position Performance Problem
- Air Conditioning (A/C) Clutch Feedback Circuit High Voltage Problem
- Cruise Vehicle Speed/Set Speed Difference Too High Problem
- PCM Stack Overrun Problem
Repair Processes :
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 for rubbing, scraping, bare wires, worn spots or melted plastic connectors. Pull the connectors apart and carefully look at the terminals (the metal parts) inside the connectors.
