OBD-II Body Error Code B0164: How to Fix It

Q: Can I still drive with OBD-II code B0164?

Yes, B0164 is a low-severity code that won't prevent safe driving. However, your climate control system may not maintain accurate temperatures, and you may experience issues with automatic climate control functions.

Q: What causes the in-car temperature sensor to fail?

Common causes include sensor age and wear, moisture exposure, damaged wiring from rodents or wear, loose electrical connections, or contamination from dust and debris in the sensor housing.

Q: How much does it cost to fix B0164 error code?

DIY repairs typically cost $20-80 for a replacement sensor. Professional repair costs range from $150-400 depending on sensor location, labor time, and whether additional components need replacement.

Q: Will B0164 cause my vehicle to fail emissions testing?

In most areas, B0164 alone won't cause emissions test failure since it's related to climate control rather than engine emissions. However, check your local regulations as some areas have stricter requirements for any stored codes.

Q: How can I prevent future B0164 codes?

Keep your vehicle's interior clean, avoid spilling liquids near climate vents, have regular HVAC system maintenance, and address any water leaks promptly. Also ensure cabin air filters are changed regularly to prevent debris buildup.

Abstract

OBD-II error code B0164 indicates a failure in your vehicle's in-car temperature sensor circuit, which is part of the climate control system. This sensor monitors cabin temperature to help your HVAC system maintain the desired climate settings. While this is typically a low-severity issue that won't prevent driving, it can affect your comfort and climate control accuracy.
