P0189 OBD-II: Fuel Temperature Sensor "B" Circuit Intermittent
P0189 Severity
Moderate
Will P0189 go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P0189?
The Fuel Temperature Sensor tells the engine control module (PCM) the temperature of the fuel. When the PCM detects an implausible signal from the Fuel Temperature Sensor, the PCM will set code P0189.
