Honda Automotive Error Code P1107: How to Fix It

Q: Can I drive with Honda error code P1107?

Yes, you can drive with P1107, but your vehicle may experience reduced fuel economy, poor acceleration, and rough idling. It's not immediately dangerous, but you should address it promptly to prevent potential engine damage and restore optimal performance.

Q: What causes Honda P1107 error code?

P1107 is typically caused by a faulty BARO/MAP sensor, damaged wiring harness, corroded electrical connections, or vacuum leaks in the intake system. Less commonly, it can be caused by a failing ECM/PCM, though this is rare.

Q: How much does it cost to fix P1107 on a Honda?

DIY repairs typically cost $20-50 for cleaning supplies and minor parts. Professional diagnosis costs $100-150, while MAP/BARO sensor replacement ranges from $150-400 depending on your Honda model and labor rates.

Q: Will P1107 cause my Honda to fail emissions testing?

Yes, P1107 will likely cause your Honda to fail emissions testing since it affects the engine management system's ability to properly control air-fuel mixture. The code must be resolved and the system must complete its readiness monitors before testing.

Q: Is P1107 the same as P0107 on Honda vehicles?

No, P1107 is a manufacturer-specific Honda code for BARO circuit low input, while P0107 is a generic OBD2 code for MAP sensor low input. Though related to pressure sensing, they indicate different specific issues within Honda's engine management system.

Abstract

Honda error code P1107 indicates a problem with the barometric pressure (BARO) sensor circuit, specifically that the signal voltage is lower than expected. This sensor helps your engine's computer adjust fuel delivery and ignition timing based on altitude and atmospheric pressure. While not immediately dangerous, this error can cause poor fuel economy and reduced engine performance.
