Guide To P2089 OBD Error Code Solutions

<<See All OBD Codes

The P2089 error code shows a reduction in engine performance which is well-defined as “A" camshaft position actuator control circuit high bank 1. In order to adjust the timing of the camshaft, newer vehicles are using a variable timing system to alter the timing in relation to the crankshaft so that the fuel efficiency and performance can be increased. The intake valves will open and close based on the rotation of the camshaft. In order to advance or delay the camshaft timing, the oil pressure is used by the PCM which changes when the valves open and close accordingly. The P2089 error will be set by the PCM if the camshaft fails to adjust as per command.

The P2089 error code refers to the A camshaft position actuator which seems to have a high voltage. The high voltage for bank 1 sensor A has been found by the vehicle’s electronic control unit which caused the P2089 error to be stored in the vehicle. You will find the check engine light on the dashboard if this error code is set in the vehicle. Apart from the warning light, a fail-safe mode is also set by the ECM, so that the damage to the vehicle is prevented. This failsafe mode will remain in the vehicle until the normal voltage range is found or the issue is repaired.

What causes this problem with the A Camshaft Position Actuator Control Circuit High Bank 1?

• The wiring harness of the camshaft position actuator might either be open or shorted.
• Failure of the variable camshaft solenoid bank 1.
• The electrical connection might be poor.
• Wrong engine timing.

1. Camshaft Position Actuator - a very rough idle or a drop in engine power shows that the camshaft position actuator is faulty which needs immediate replacement.
2. Crankshaft Valves - An increase in the internal engine pressure can likely damage the crankshaft valves. Get the replacement for the damaged crankshaft valves from PartsAvatar.
3. Powertrain Control Module - You will likely face performance issue in your engine if the powertrain control module is faulty. Also, the engine may fail to start and there might be sparking issues. Replace your powertrain control module if you happen to witness these symptoms in your vehicle.
4. Oil Control Valve - The oil control valve is responsible for reducing the gas emission and increasing the performance of the engine. Replace the faulty oil control valve to avoid the P2089 error code getting stored.
5. Engine Wiring Connectors - The damaged engine wiring connectors have to be replaced quickly as they connect various components to the engine. Fix it soon to avoid P2089 error.

Have you ever wondered why it is so important to know the symptoms of the problem? Well, it is extremely essential to know the symptoms of the problem in order to detect it. Keeping this in mind, let’s throw some light on a few common symptoms of OBD error code P2089

Common Symptoms

• The check engine light will be initiated.
• Idling will be poor.
• Fuel economy will be lower than normal.
• Acceleration will be very poor.
• Few attempts will be made to start.
• Electrical wires might be corroded.

To correct this issue you might need to undergo few replacements for the defective parts such as:

• The wiring harness has to be repaired or replaced.
• Changing the variable camshaft solenoid for bank 1.
• Poor electrical connections must be fixed.
• Fixing the engine timing.

Here are some steps which you should follow in order to diagnose this P2089 fault code:

• The very first step, which a trained professional will do is that he will check for any codes which include the pending and history of codes that are stored in the ECU.
• The mechanic has to note down each and every code along with the freeze frame data.
• Secondly, each of these code, must be cleared and the mechanic has to test drive the vehicle. While performing the test drive, the mechanic will try his best to replicate the condition from the code by locating it in the first place.
• Once the road test is done and the P2089 error is confirmed in the vehicle, the mechanic will visually inspect for any damaged or broken wires or components.
• After this, the mechanic will be using a scan tool to verify the readings of the camshaft sensor data stream as well as the timing advance.
• As a next step, the mechanic will use a multimeter to see if proper voltage is available at the camshaft position actuator.
• Lastly, the mechanic will verify the vehicle to see if there is any skipped tooth on the timing belt or the chain.

Common Mistakes When Diagnosing the P2089 Code

One of the most common errors that is made while diagnosing the P2089 error is that the mechanic fails to follow the diagnostic procedure in a logical order. Failure to follow these steps in the correct order might lead to misdiagnosis and wasting both money and time.
