P2B2F Vauxhall Zafira Diagnostic Trouble Code
P2B2F Vauxhall Zafira code definition:
P2B2F is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Vauxhall Zafira.
P2B2F Vauxhall Zafira is triggered when the bank 1 camshaft position sensor doesn't match the signal from the crankshaft position sensor. Any code that causes the vehicle's engine to die while running should be fixed as soon as possible, as it can be dangerous for both the vehicle and the passengers of the vehicle.
Symptoms
Symptoms of a P2B2F Vauxhall Zafira 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.

Common Misdiagnoses
- 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
- Kick-Down Switch Failed Short Problem
- Park/Neutral Postion (PNP) Switch Circuit Engine Torque Signal Circuit Problem
Repair Processes :
Now, clear the codes and test-drive the vehicle to see if the code is reset.
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.
Replace the oxygen sensor that is downstream from the catalytic converter on the side of the engine that does not contain cylinder #1. Also, if a oxygen sensor code stating "heater circuit malfunction" the sensor has most probably failed.
