Chrysler P1192 Error Code: How to Fix It

Q: What causes Chrysler P1192 error code?

P1192 is typically caused by a faulty inlet air temperature sensor, damaged wiring, corroded electrical connections, or vacuum leaks in the intake system that affect sensor readings.

Q: Can I drive with P1192 code?

Yes, you can typically drive with this code as it's not critical to safety, but you may experience reduced fuel economy, rough idling, or poor engine performance until the issue is resolved.

Q: How much does it cost to fix P1192?

If it's just the sensor, replacement parts cost $15-40. If professional repair is needed, expect $100-200 including labor. More extensive wiring repairs could cost more.

Q: How do I test inlet air temperature sensor?

Use a multimeter to check resistance across the sensor terminals. At room temperature, it should read 2,000-3,000 ohms. You can also check that resistance changes as temperature changes.

Abstract

The P1192 error code indicates your Chrysler's inlet air temperature sensor circuit is reading abnormally low values. This sensor helps your engine's computer determine the proper air-fuel mixture, and when it malfunctions, you may experience poor performance or reduced fuel economy.
