Laymans terms

This code means that the computer in your car found a problem with the temperature sensor inside the transmission. It's saying that the sensor is not giving the right temperature readings when the transmission is cold.

Explanation

The Transmission Control Module (TCM) monitors the temperature sensor within the transmission. If the sensor's readings do not match expected values, especially in lower temperature ranges, this code is triggered.

Technical description

The P182A code is set when the TCM detects a correlation issue between the internal switch-on temperature sensor and the transmission fluid temperature sensor. This typically occurs when the sensors provide inconsistent readings, particularly when the transmission is operating in a lower temperature range.

Symptoms

• Check Engine Light is on

• Transmission may not shift properly

• Poor fuel economy

Common Causes

• Faulty temperature sensor

• Wiring issues or poor connections

• Faulty Transmission Control Module (TCM)

• Use an OBD-II scanner to confirm the code.

• Inspect the wiring and connectors for damage or corrosion.

• Test the temperature sensor for proper operation.

Repair procedures

• Replace the faulty temperature sensor.

• Repair or replace damaged wiring or connectors.

• Replace the TCM if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools

This code has been associated with sensor issues in vehicles with automatic transmissions, particularly in colder climates.

Urgency level

Moderate – It is advisable to address this issue soon to prevent further transmission problems.

Testing conditions

• Vehicle at operating temperature

• Transmission in a lower temperature range

Component location

The temperature sensor is typically located inside the transmission or near the transmission fluid pan.

FAQs

Q: Can I drive with a P182A code?
A: It's possible to drive short distances, but it's best to have the issue checked soon to avoid further damage.

Q: How can I reset the P182A code?
A: You can reset the code using an OBD-II scanner, but it's important to fix the underlying issue first.
