Title: Diagnostic Guide: Understanding and Resolving the P0068 Error Code in the Chevrolet Cruze


The Chevrolet Cruze has established itself as a popular compact sedan, known for efficiency, reliability, and performance. However, like any modern vehicle, it is not immune to occasional mechanical issues. One such issue that has been reported by Cruze owners is the P0068 error code. In this article, we aim to shed light on what this code signifies, its potential causes, and the steps to diagnose and resolve it, ensuring that your Cruze continues to deliver a smooth and trouble-free driving experience.

Understanding the P0068 Error Code:

The P0068 error code pertains specifically to the Chevrolet Cruze’s throttle position sensor (TPS) and stands for “MAP/MAF – Throttle Position Correlation.” It indicates a mismatch between the TPS and the manifold absolute pressure (MAP) or mass air flow (MAF) sensors. Consequently, the engine control module (ECM) detects an inconsistency in the data received from these sensors, triggering the code P0068.

Potential Causes of the P0068 Code:

1. Defective Throttle Position Sensor (TPS): A worn-out or malfunctioning TPS can lead to inaccurate readings, triggering the error code P0068.

2. Faulty Manifold Absolute Pressure (MAP) Sensor: A damaged or faulty MAP sensor may also cause a discrepancy in the TPS-MAP correlation, resulting in the P0068 error code.

3. Defective Mass Air Flow (MAF) Sensor: Similar to the MAP sensor, a malfunctioning MAF sensor can generate inconsistent data, leading to the P0068 fault.

4. Wiring or Connector Issues: Damaged wiring or loose connections between the TPS, MAP, or MAF sensors and the ECM can disrupt the necessary signal communication, prompting the P0068 code.

5. ECM Malfunction: In rare cases, a faulty engine control module itself may be the root cause of the P0068 error code.

Diagnostic and Resolution Steps:

1. Preliminary checks: Begin by checking the wiring harness and connectors for any visible damage or loose connections. Ensure they are properly secured and free from corrosion.

2. TPS Inspection: Evaluate the throttle position sensor by referring to the manufacturer’s manual or by seeking professional assistance. If any damage or abnormality is detected, replace the TPS as necessary.

3. MAP Sensor Testing: Test the manifold absolute pressure sensor using a multimeter or refer to the vehicle’s service manual. Replace the MAP sensor if it fails to meet the specified parameters.

4. MAF Sensor Verification: Verify the operation of the mass air flow sensor by following the manufacturer’s recommendations or consulting a mechanic. If it is found faulty, consider replacing the MAF sensor.

5. Repair or Replace: Repair or replace any damaged wiring or connectors detected during the inspection, ensuring a secure and efficient connection between the sensors and the ECM.

6. ECM Evaluation: In cases where all other potential causes have been ruled out, consider seeking professional assistance to evaluate the ECM for potential malfunctions.


The P0068 error code in the Chevrolet Cruze, although not overly common, can cause inconvenience and potential drivability issues. By understanding its causes and following the diagnostic steps mentioned above, you can effectively address the P0068 code, ensuring your Cruze operates optimally for years to come. If you encounter difficulties throughout the process, it is always advisable to consult with a professional technician or authorized dealer, who possesses the expertise to efficiently diagnose and resolve the issue.
