P0938 Dodge Code - Hydraulic Oil Temperature Sensor Range/Performance
Quick Answer
The P0938 diagnostic trouble code (DTC) for Dodge vehicles refers to the Hydraulic Oil Temperature Sensor Range/Performance. Common causes include Faulty Hydraulic Oil Temperature Sensor: The sensor itself may be defective or damaged, causing inaccurate temperature readings, Wiring or Connector Issues: Damaged or corroded wiring, connectors, or terminals in the sensor circuit can disrupt the signal transmission, PCM Malfunction: A malfunctioning PCM can also trigger the P0938 code by misinterpreting the sensor's signal. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0938 Dodge Description
The P0938 diagnostic trouble code (DTC) for Dodge vehicles refers to the Hydraulic Oil Temperature Sensor Range/Performance. This code indicates that the powertrain control module (PCM) has detected an issue with the hydraulic oil temperature sensor's signal. The hydraulic oil temperature sensor is a crucial component in the vehicle's transmission system, as it monitors the temperature of the hydraulic fluid that is essential for proper transmission operation.
Common Causes of P0938 Dodge
- Faulty Hydraulic Oil Temperature Sensor: The sensor itself may be defective or damaged, causing inaccurate temperature readings.
- Wiring or Connector Issues: Damaged or corroded wiring, connectors, or terminals in the sensor circuit can disrupt the signal transmission.
- PCM Malfunction: A malfunctioning PCM can also trigger the P0938 code by misinterpreting the sensor's signal.
- Low Transmission Fluid Level: Insufficient transmission fluid levels can affect the sensor's ability to accurately measure temperature.
- Extreme Temperature Conditions: Operating the vehicle in extreme temperature conditions can also impact the sensor's performance.
Symptoms of P0938 Dodge
- Check Engine Light: The most common symptom associated with the P0938 code is the illumination of the check engine light on the vehicle's dashboard.
- Transmission Issues: The vehicle may experience erratic shifting, slipping gears, or difficulty engaging gears due to the faulty hydraulic oil temperature sensor.
- Decreased Fuel Efficiency: A malfunctioning sensor can lead to improper transmission fluid temperature regulation, resulting in decreased fuel efficiency.
- Transmission Overheating: In severe cases, the transmission system may overheat due to inaccurate temperature readings from the sensor.
- Transmission Fluid Leaks: A damaged sensor or sensor circuit can cause leaks in the transmission system, leading to fluid loss and potential damage.
How to Fix P0938 Dodge
- Diagnose the Issue: Use a scan tool to retrieve the DTC and inspect the hydraulic oil temperature sensor, wiring, and connectors for any visible damage.
- Replace the Hydraulic Oil Temperature Sensor: If the sensor is faulty, replace it with a new one and ensure proper installation.
- Repair Wiring or Connectors: Repair or replace any damaged wiring, connectors, or terminals in the sensor circuit to restore proper signal transmission.
- Clear DTCs: Clear the DTC from the PCM's memory after completing the repair process to reset the check engine light.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the transmission system is functioning properly.
Cost to Fix P0938 Dodge
The typical repair costs for addressing the P0938 code on a Dodge vehicle can range from $150 to $400, including parts and labor. However, specific diagnosis time and labor rates at auto repair shops may vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check local rates for a more accurate estimate. Keep in mind that rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less for repairs.
