Common Symptoms

  • Check Engine Light illuminated
  • Rough idle from Bank 2 cylinders
  • Reduced engine power
  • Possible engine knocking

Probable Causes (Ranked by Likelihood)

  • Short to ground in Bank 2 VVT solenoid wiring Very High
  • Internally shorted Bank 2 VVT solenoid High
  • Corroded connector on Bank 2 Moderate
  • PCM Bank 2 driver circuit fault Low

Step-by-Step Diagnostic Procedure

  1. Measure Bank 2 intake VVT solenoid resistance. Below 5 ohms indicates an internal short.

  2. Disconnect solenoid and check harness for short to ground with multimeter.

  3. Inspect wiring for chafing, especially where harness contacts engine or body.

  4. Compare Bank 1 and Bank 2 solenoid resistance values. They should be within 1 ohm of each other.

Frequently Asked Questions

What is circuit low on the VVT solenoid?

Circuit low means the PCM detects lower resistance or voltage than expected. This is usually caused by a short to ground in the wiring or a failed solenoid.

How do I test the Bank 2 VVT solenoid?

Disconnect the solenoid and measure resistance with a multimeter. Compare to specs in your service manual. Also apply 12V directly to see if the solenoid clicks.

Can I drive with P0083?

You can drive short distances. Bank 2 cylinders may not have optimal valve timing, leading to reduced performance and increased emissions.
