Pontiac G6 recurring MAP sensor issues with Service Traction light and intermittent chugging on Pontiac G6

Some Pontiac G6 owners report experiencing recurring MAP sensor issues, accompanied by the Service Traction light activation and intermittent chugging. These issues may arise from a common communication error that triggers the Service Traction light. Additionally, some owners find that the chugging sensation and jerking are linked to the traction control and ABS lights illuminating, potentially due to a faulty wiring harness. In certain cases, a lean air-fuel mixture indicated by OBD II codes P0171 and P0174 can also cause the Service Traction light to flicker. To address these problems, owners are advised to check the connections at the body control module for security, investigate the wiring harness for faults, and inspect the air filter to resolve any lean air-fuel mixture issues.
