P2092 OBD-II Trouble Code: A Camshaft Position Actuator Control Circuit Low Bank 2

What the P2092 code means?

P2092 is an OBD-II generic code for the engine control module (ECM) detecting the A camshaft position actuator control circuit is low on bank 2.

What causes the P2092 code?

• The ECM monitors the return voltage from the camshafts actuator circuit and will turn on the Check Engine light and set code P2092 when the voltage return is below the specified voltage for bank 2 camshaft position

• A broken wire or connector for the supply voltage circuit from the power supply relay

• An open wire on the power supply circuit

• An open or short on the return signal wire to the ECM

• An open or shorted camshaft control actuator for the bank 2 camshaft actuator

What are the symptoms of the P2092 code?

• The Check Engine light will be illuminated and the code is set in ECM memory as a fault.

• The engine may have low power on acceleration if the camshaft is set too far advanced when it failed.

• The engine may have low power at higher speeds if the camshaft actuator failed in the retarded timing phase.

• The engine fuel mileage will go down for the city or highway.

How does a mechanic diagnose the P2092 code?

• Scans codes and documents the code in the ECM and looks at the freeze frame data for failure.

• Measures the voltage on the camshaft actuator supply circuit for bank 2.

• Measures the resistance of the camshaft actuator for bank 2 and checks to specifications.

• Diagnoses code P2092 following the manufacturer pinpoint tests.

• Checks the wiring and connector to the supply circuit for shorts, breaks or loose connections to the actuator circuit for bank 2.

Common mistakes when diagnosing the P2092 code?

• Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired

• Failing to clear the ECM codes after the codes are fixed

• Failing to follow the pinpoint test completely causing the wrong part to be diagnosed. Sometimes the wrong oil being used is common

How serious is the P2092 code?

Code P2092 is major failure in the camshaft actuator control circuit on bank 2 and the camshaft will not be able to advance or retard as required and a loss of power will result. The engine may go into failure management mode on some vehicles and limit the throttle control.

What repairs can fix the P2092 code?

• Replace the camshaft control actuator assembly for bank 2.
• Repair an open or short in the actuator wiring or connector.
• Replace the ECM for the control circuit failure.
• Replace the actuator power relay for shorted contacts.

Additional comments for consideration regarding the P2092 code

Code P2092 is for vehicles that have a camshaft advance and retard actuator. Some vehicles use these actuators to control oil flow to the camshaft mechanism. The most common failure in these systems is the actuator goes bad and will not control the circuit properly. The system is dependent on the correct oil viscosity of oil to be used or problems with advancing and retarding the camshafts are common.
