Description of OBD-II DTC Trouble Code
The “B” Camshaft Position – Timing is Over-Advanced or the System Performance is not optimal (Bank 1).
What does this mean?
This diagnostic trouble code (DTC) is a generic powertrain code that applies to OBD-II equipped vehicles, such as Toyota, VW, Honda, Chevrolet, Hyundai, Audi, Acura, etc.
A P0014 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module) or ECM (engine control module). VVT is a technology used in the engine to improve power or efficiency at different running points.
This code specifically relates to the camshaft (cam) timing. If the cam timing exceeds a set limit (over-advanced), the engine light will illuminate and the code will be set. Bank 1 refers to the side of the engine containing cylinder #1. The “B” camshaft can be either the “exhaust,” “right,” or “rear” camshaft. Left/Right and Front/Rear are determined from the driver’s seating position.
Potential Symptoms
A P0014 DTC will likely result in one of the following symptoms: hard starting, poor idle, and/or stalling. There may be other potential symptoms as well. When trouble codes are set, the MIL (malfunction indicator lamp), also known as the check engine light, will illuminate.
Causes
A P0014 DTC trouble code may be caused by one or more of the following:
Possible Solutions
This DTC code is the result of a mechanical fault in the VCT unit or related components, so there is no need for electrical diagnosis. Refer to the vehicle-specific repair manual to perform component tests for the VCT unit. Note: Dealer technicians have advanced tools and the ability to follow detailed troubleshooting steps, including testing components using a scan tool.
