|What are the Possible Causes of the P1106 Code?

  • Engine Control Module (ECM) outdated or incorrect software
  • Faulty Engine Control Module (ECM)

|How to Fix the P1106 Code?

Start by checking 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 code 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.

|What is the cost to diagnose the P1106 code?

Labor: 1.0

The cost to diagnose the P1106 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|What are P1106 code possible symptoms?

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

|What Does the P1106 Code Mean?

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.
