P0014 - Camshaft Position "B" - Overdue or System Performance (Bank 1)

OBD-II DTC Malfunction Code – P0014 – Description

P0014 - Camshaft position "B" - system overtime or performance (bank 1)

What does trouble code P0014 mean?

This Diagnostic Trouble Code (DTC) is a generic transmission code, which means it applies to OBD-II equipped vehicles including but not limited to Toyota, VW, Honda, Chevrolet, Hyundai, Audi, Acura, etc.

Code P0014 refers to the VVT ​​(Variable Valve Timing) or VCT (Variable Valve Timing) components and the vehicle's PCM (Powertrain Control Module) or ECM (Engine Control Module). VVT is a technology used in an engine to give it more power or efficiency at various points of operation.

It consists of several different components, but the P0014 DTC is specifically related to camshaft (cam) timing. In this case, if the cam timing exceeds the set limit (over-growth), the engine light will illuminate and a code will be set. Bank 1 is the side of the engine that contains cylinder #1. Camshaft "B" must be an "exhaust", "right" or "rear" camshaft. Left/Right and Front/Rear are defined as if viewed from the driver's seat.

Possible symptoms

DTC P0014 will most likely result in one of the following: abrupt start, poor idle, and / or engine stalling. Other symptoms are also possible. Of course, when the DTCs are set, the malfunction indicator lamp (engine malfunction indicator lamp) comes on.

• Starting the engine can be difficult if the camshaft is locked too far forward.
• Fuel consumption will be reduced due to the fact that the camshafts are not in the optimal position for good fuel consumption.
• The engine may run rough or stall depending on the position of the camshaft.
• Engine emissions will cause the vehicle to fail the emissions test.

Note : Symptoms may vary depending on the position of the camshaft when the camshaft phaser has stopped shifting timing.

Causes of the P0014 code

The P0014 DTC can be caused by one or more of the following:

• Incorrect valve timing.
• Wiring problems (harness / wiring) in the intake timing control solenoid valve system
• Constant oil flow into the VCT piston chamber
• Defective directional valve control solenoid (stuck open)
• The exhaust camshaft extended too far when the ECM commanded the camshaft to slow down to a lower timing level.
• The viscosity of the oil is too high and the passages become clogged, resulting in restricted oil flow to and from the camshaft shifters.
• The camshaft phaser is locked in the forward position.
• The oil control solenoid on the camshaft axis 1 may be shorted in the open position.

Possible solutions

This DTC is the result of a mechanical problem with the VCT or related components, so an electrical diagnosis is not necessary. Refer to your specific vehicle repair manual to check the VCT unit components. Notes. Dealer technicians have advanced tools and the ability to follow detailed troubleshooting instructions, including the ability to test components with a diagnostic tool.

HOW DOES A MECHANIC DIAGNOSTIC CODE P0014?

• Performs a visual inspection of the connector, wiring, or valve for OCV issues for the bank 1 exhaust camshaft.
• Check the engine oil level and condition of the oil to see if it is full and has the correct viscosity.
• Scans and documents engine codes and displays freeze frame data to see when a code was set
• It clears all codes, then starts the engine to see if code P0014 returns and the fault is still present.
• Check the timing data when the OCV is disconnected from the exhaust camshaft to see if the timing changes. The change indicates that the valve is working and the problem is in the wiring or the ECM.
• Performs manufacturer spot tests for code P0014 and repairs as needed.

Note . Follow the manufacturer's recommended spot testing to reduce the problem as each engine can be tested differently and possible internal engine damage can be caused if testing is not done according to the correct procedure.

COMMON ERRORS WHEN DIAGNOSING CODE P0014?

Follow these simple guidelines to avoid mistakes:

• Perform a visual inspection of the most common problems to ensure that all electrical connectors are tight and not corroded.
• Check your engine oil to make sure it is full, clean, and of the correct viscosity.
• Tests to check that the code keeps returning before further tests are done.
• The manufacturer's testing procedures should be followed step by step to avoid misdiagnosis and replacement of good quality components.
• Do not replace any sensors or components unless tests reveal a problem.

HOW SERIOUS CODE P0014 IS?

• The engine may run rough and stall or have trouble starting.
• Fuel consumption may increase due to deposits on valves and engine pistons.
• Driving the vehicle for extended periods of time with the camshaft at the wrong time can cause the valves to contact the piston if the timing chain has jumped over the gear teeth.

WHAT REPAIRS CAN FIX CODE P0014?

• Clearing trouble codes and performing a road test
• Change oil and filter using correct engine oil viscosity.
• Repair or replace bank 1 exhaust camshaft oil control valve harness.
• Bank 1 Exhaust Camshaft Oil Valve Replacement
• Repair or replace the timing chain and camshaft shifters in accordance with the service manual.

ADDITIONAL COMMENTS TO BE AWARE OF CODE P0014

If the camshaft drive chain has been mis-timing due to worn guides or tensioner failure, this can cause this code. Perform the appropriate diagnostic procedures necessary to properly diagnose the timing chain or OCV system.
