Code U1437 Chrysler Description
The U1437 Chrysler code indicates that the Powertrain Control Module (PCM) has detected an implausible intake air temperature message. This means that the PCM has received a signal from the intake air temperature sensor that is outside of the expected range or does not correlate with other sensor readings. The intake air temperature sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for determining the air-fuel mixture and ignition timing. An incorrect reading from this sensor can lead to poor engine performance, decreased fuel efficiency, and increased emissions.
Common Causes of U1437 Chrysler
- Faulty intake air temperature sensor
- Wiring or connector issues in the intake air temperature sensor circuit
- PCM software glitch
- Intake air temperature sensor reading out of range
- Intake air temperature sensor contaminated or damaged
Symptoms of U1437 Chrysler
- Check Engine Light illuminated
- Reduced engine power
- Rough idling or stalling
- Decreased fuel efficiency
- Increased emissions
How to Fix U1437 Chrysler
- Begin by connecting a diagnostic scanner to the vehicle's OBD-II port to retrieve the specific trouble code and freeze frame data.
- Inspect the intake air temperature sensor and its wiring for any visible damage or corrosion. Replace the sensor if necessary.
- Check the intake air temperature sensor circuit for continuity and proper voltage. Repair any wiring or connector issues as needed.
- Clear the trouble code from the PCM's memory and perform a test drive to ensure the code does not return.
- If the code persists, further diagnostics may be required to pinpoint the exact cause, such as testing the PCM or checking for software updates.
Cost to Fix U1437 Chrysler
The cost of repairing an implausible intake air temperature message can vary depending on the specific cause of the issue.
