Error code

OBD2 P0211

OBD2P0211
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Injector Circuit/Open - Cylinder 11.

Severity

highThe vehicle may be drivable but performance will likely suffer and there's a risk of further engine damage.

Summary

P0211 indicates an issue with the fuel injector circuit for cylinder 11, meaning there's likely a problem with either the injector itself or its electrical connection.

Symptoms

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

Common Causes

  • Failed fuel injector in cylinder 11
  • Faulty wiring or connector for the fuel injector circuit of cylinder 11
  • Problem with the Powertrain Control Module (PCM) driver

Diagnosis

  1. Visually inspect the fuel injector and its connections for any obvious issues.
  2. Use a scan tool to check for misfire codes (P0301-P0308) that might indicate which cylinder is affected.
  3. Test the control circuit using a noid light by disconnecting the injector and inserting the light into the connector. The light should flash when cranking the engine.
  4. Check for power to the injector using a test light connected to ground and touching it to the B+ pin on the injector connector.
  5. Verify that the PCM is properly grounding the injector by attaching one end of a test light to battery power and the other to the ground side of the injector connector. The light should illuminate when cranking the engine.
  6. Use a digital multimeter to check for continuity between the PCM and injector, or measure resistance at the injector terminals to determine if it needs replacement.

Fixes

  • Replace the faulty fuel injector in cylinder 11.

FAQ
