P2093 code definition

The P2093 code is a general OBD-II diagnostic trouble code indicating a fault with the “A” camshaft position actuator control circuit high bank 2.

What the P2093 code means

The camshaft position sensor “A” is indicating the intake side of the engine. Bank 2 is generally referring to the passenger side. The camshaft position actuator is used by the engine control module (ECM) to change engine timing. When the circuit has high voltage, the ECM will set a P2093 code.

The code will cause the Check Engine Light to be illuminated on the dashboard. In addition, a failsafe mode will be set which places the timing in a fixed setting to prevent damage. This failsafe mode will remain until the voltage comes back into range or the fault is repaired.

What causes the P2093 code?

Common causes of the P2093 code are:

  • Faulty variable valve timing solenoid “A” bank 2
  • Open or short in the camshaft actuator harness
  • Camshaft timing is wrong
  • Oil level low or low oil pressure
  • Failed timing belt or chain

What are the symptoms of the P2093 code?

Symptoms can be proceeded by the Check Engine Light. The vehicle may have a poor idle, a lack of engine power, and poor fuel economy.

How does a mechanic diagnose the P2093 code?

The first step a qualified technician should take is to check what codes are stored in the ECM. All codes stored in the ECM will be noted for use later along with any freeze frame data present. Then all codes will be cleared and a test drive performed. The test drive should be performed under similar conditions as the freeze frame data if possible. Then a visual inspection will be performed to look for any obvious defects. Next, the oil level will be checked. Finally, the technician will use a multimeter to check for the reference voltage at the camshaft position actuator.

Common mistakes when diagnosing the P2093 code

Mistakes are commonly seen when steps are not completed in order or when steps are skipped entirely. This leads to good parts being replaced mistakenly and a waste of time and money.

How serious is the P2093 code?

The P2093 can be seen in vehicles with serious mechanical issues. If it is suspected the timing belt or chain is the cause of the fault, the vehicle should not be driven.

What repairs can fix the P2093 code?

Repairs that can fix the P2093 code are:

Additional comments for consideration regarding the P2093 code

An advanced level scan tool is critical for diagnosing the P2093 code. This is due to the advanced scan tool's ability to access the ECM live datastream. This datastream can be used to monitor sensor data while the vehicle is operated to look for faults.
