Description of OBD-II DTC Trouble Code
The “B” Camshaft Position – Timing Over-Advanced or System Performance (Bank 2) is a diagnostic trouble code (DTC) that is applicable to OBD-II equipped vehicles, such as Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, etc.
A P0024 code pertains 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 an engine technology that allows for improved power or efficiency at different running points.
If the cam timing exceeds a specified limit (over-advanced), the engine light will illuminate and the code will be triggered. The “B” camshaft refers to the exhaust, right, or rear camshaft. A P0024 trouble code is similar to a P0021 code, but it specifically relates to camshaft “B” instead of “A”. Bank 2 refers to the side of the engine that does not contain cylinder #1.
Meaning of the Code
A P0024 DTC will likely result in one or more of the following symptoms: hard starting, poor idle, and/or stalling. Other potential symptoms may also be present. When trouble codes are set, the malfunction indicator lamp (check engine light) will illuminate.
Possible Causes
A P0024 DTC trouble code may be caused by any of the following:
Potential 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 for performing component tests on the VCT unit. Note: Dealer technicians have advanced tools and the ability to follow detailed troubleshooting steps, including testing components using a scan tool.
