This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the temperature sensor inside the transmission. It's like when a thermometer isn't working right and gives the wrong temperature.
The code P182D indicates that the Transmission Control Module (TCM) is receiving inconsistent or incorrect temperature readings from the internal temperature sensor, particularly in the lower temperature range.
The P182D code is triggered when the TCM detects a discrepancy between the expected and actual readings from the internal temperature sensor. This sensor monitors the temperature of the transmission fluid to ensure optimal performance. If the sensor readings are not within the expected range, particularly at lower temperatures, the TCM may not be able to properly control transmission operations.
• Check Engine Light is on
• Transmission may shift improperly
• Poor fuel economy
• Faulty transmission fluid temperature sensor
• Wiring issues or poor electrical connections
• Malfunctioning Transmission Control Module (TCM)
TCM: Transmission Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the transmission fluid temperature sensor for proper operation.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the TCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Malibu
• Ford Focus
• Toyota Camry
• Regularly check and maintain transmission fluid levels.
• Inspect electrical connections for corrosion.
• Schedule routine transmission services.
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Have the vehicle inspected by a professional mechanic.
Check your vehicle's warranty coverage for powertrain components, as this may be covered under a manufacturer's warranty.
This code is relatively uncommon and typically associated with sensor or wiring issues in vehicles with electronic transmission controls.
Moderate – It's important to address this issue to prevent potential transmission damage.
Driving with a faulty transmission sensor can lead to improper shifting and potential safety hazards.
• Vehicle must be at operating temperature.
• Transmission fluid should be at the correct level.
The transmission fluid temperature sensor is typically located inside the transmission housing or on the transmission valve body.
Q: Can I drive with a P182D code?
A: It's not recommended to drive for long periods with this code, as it may lead to transmission issues.
Q: How do I reset the P182D code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
