P167A Chrysler Code - Calibration Mismatch

Quick Answer

During the initial ignition on, the Transmission Control Module (TCM) receives the calibrated data from the EEPROM assembly inside the transmission and stores this information in the EEPROM of the TCM. Common causes include Transmission Control Module (TCM) Relearn Procedure Not Performed. 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.

What it means: P167A Chrysler indicates Calibration Mismatch.
Common causes: Common causes include Transmission Control Module (TCM) Relearn Procedure Not Performed.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P167A Chrysler Description

During the initial ignition on, the Transmission Control Module (TCM) receives the calibrated data from the EEPROM assembly inside the transmission and stores this information in the EEPROM of the TCM. At every ignition on, the TCM compares the stored data in the EEPROM to the transmitted data from the EEPROM in the transmission. If the calibration data does not match the DTC will set and the MIL will illuminate after one failure.

Frequently Asked Questions about P167A Chrysler Code

1. What does the OBDII code P167A mean on a Chrysler vehicle?

P167A indicates a "Calibration Mismatch," meaning the powertrain control module (PCM) has detected a discrepancy between the software or calibration data in the vehicle's control modules.

2. What are the common symptoms of the P167A code?

Symptoms may include the check engine light turning on, decreased engine performance, poor fuel efficiency, or communication issues between vehicle modules.

3. What causes the P167A code to appear?

The code is typically caused by incorrect PCM programming, a recent module replacement without proper calibration, or a software update that didnâ€™t match the vehicleâ€™s configuration.

4. Can the P167A code cause drivability issues?

Yes, depending on the severity of the calibration mismatch, it can lead to poor performance or erratic behavior in the engine or transmission.

5. How is the P167A code diagnosed?

A technician will use a scan tool to verify the code, check the module software versions, and compare them to the vehicleâ€™s specifications to identify mismatched calibration.

6. Can I fix the P167A code without replacing parts?

Yes, in many cases, the issue can be resolved by reprogramming or updating the PCM or other affected control modules with the correct calibration files.

7. Is the P167A code related to a recent repair or software update?

It often is. If a control module was replaced or updated recently, the new software may not match the vehicleâ€™s configuration, triggering the code.

8. How much does it cost to fix the P167A code?

The cost varies but generally includes labor for diagnosing and reprogramming the PCM or other modules, which can range from $100 to $300 at a repair shop.

9. Can I drive my Chrysler with the P167A code?

While the vehicle may remain drivable, itâ€™s not recommended because the mismatch could lead to performance issues or cause damage to other systems over time.

10. What tools are needed to fix the P167A code?

A professional-grade OBDII scanner and access to Chryslerâ€™s technical service information or dealership tools are required to diagnose and reprogram the affected modules.
