    Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

P1106 Tech Notes

Sometimes the P1106 is set when Engine Control Module (ECM) can't read the BARO Sensor Circuit. Before replacing any parts try performing the ECM reset procedure.
- Clear code
- Start the engine
- Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on, then let it idle
- Test-drive with the A/T in 2nd position, M/T in 4th gear
- Press accelerator pedal over 1/2 way down for five seconds
- Check for codes again
- If the codes comes back ECM may need to be replace. If codes don't came back, problem is repaired.

P1106 Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Engine rough idle
  • Engine hesitation

P1106 Meaning

The Barometric Pressure (BARO) sensor is built into the Engine Control Module (ECM) and monitors atmospheric pressure. The ECM estimates appropriate intake airflow from the Manifold Absolute Pressure (MAP) sensor output voltage and BARO sensor output voltage. If the BARO sensor output voltage is a specified value or more, the ECM detects a malfunction and a code is stored.
