P0170 is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Caterham Superseven.
P0170 Caterham Superseven is triggered when the bank 1 camshaft position sensor doesn't match the signal from the crankshaft position sensor. The PCM then uses this data to provide the right strategies for the fuel delivery and ignition timing of the engine.
Symptoms
Symptoms of a P0170 Caterham Superseven diagnostic trouble code may include:
- Rich or lean exhaust
- Fuel pressure too low
- Engine surge
- 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.
- Faulty IMRC actuator relay (if equipped)
|
Common Misdiagnoses
- Crankshaft Position Sensor Circuit Performance Problem
- TP Sensor Learn Not Complete Problem
- Low Coolant Circuit Problem
- Cruise Control System - Vehicle Accel Too High Problem
- Kick-Down Switch Failed Short Problem
Repair Processes :
Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector.
If the scan tool has that capability, and the scan tool can operate the IMRC valves, then the problem is either resolved and a simple code clearing is all that's left or a new PCM would be called for.
