P1106 ACURA Possible Causes
- Outdated or incorrect Engine Control Module (ECM) software
- Faulty Engine Control Module (ECM)
How to Fix P1106 ACURA Code?
Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
What Does It Mean?
Sometimes P1106 is set when the Engine Control Module (ECM) cannot read the BARO sensor circuit. Before replacing parts, try performing the ECM reset procedure.
– Clear the code
– Start the engine
– Maintain engine at 3000 RPM with no load (in park or neutral) until the radiator fan turns on, then let it idle
– Road test with A/T in 2nd position, M/T in 4th gear
– Press accelerator pedal halfway down for five seconds
– Check for codes again
– If codes return, the ECM may need to be replaced. If codes don’t return, the problem is fixed.
Possible Symptoms
Check Engine Light on (or Service Engine Soon warning light)
Engine rough idle
Engine hesitation
P1106 ACURA Meaning
The Barometric Pressure (BARO) sensor is built into the Engine Control Module (ECM) and monitors atmospheric pressure. The ECM estimates the appropriate intake air flow from the Manifold Absolute Pressure (MAP) sensor output voltage and the BARO sensor output voltage. If the BARO sensor output voltage is at a specified value or higher, the ECM detects a malfunction and a code is stored.
