Model: Corvette Fault Code: B0361 Posted: 2019-10-01 12:25

A 1999 Chevrolet Corvette owner is experiencing error codes C1291 and B0361. These diagnostic trouble codes (DTCs) are related to the vehicle's engine management system and can indicate issues with the intake manifold pressure sensor or throttle body control. Error code C1291 typically points to a problem with the intake manifold absolute pressure (MAP) sensor, while B0361 may suggest an issue with the throttle position sensor or its associated circuit. Both codes are common in older Corvette models and can lead to poor engine performance, stalling, or difficulty starting. It is recommended to inspect the sensors for faults, check wiring connections, and ensure proper grounding. A professional scan tool should be used to confirm the exact nature of each code and to monitor live data during operation.
