OBD2P0205
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Injector Circuit/Open - Cylinder 5.

Severity

moderateCan drive, but performance issues and potential damage may occur if not addressed.

Summary

P0205 indicates an issue with the fuel injector circuit for cylinder 5, meaning the powertrain control module (PCM) detected a malfunction in this specific injector's electrical operation.

Symptoms

  • Engine misfire
  • Engine stalls
  • Engine cranks but doesn't start

Common Causes

  • Failed fuel injector
  • Faulty wiring or connector in the injector circuit
  • Problem with the PCM (injector driver)

Diagnosis

  1. Perform a visual inspection of the injectors and connections.
  2. Check for misfires with a scan tool to identify which cylinder is affected.
  3. Use a noid light to check if the control circuit to the injector is functioning properly.
  4. Test power supply to the injector using a test light.
  5. Verify continuity between the PCM and injector using a digital multimeter.
  6. Measure resistance between the two terminals of the fuel injector.
  7. Use an oscilloscope to view waveform patterns for detailed analysis.

Fixes

  • Replace faulty fuel injector or repair wiring and connectors.
