P215C Severity
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
The Wheel Speed Sensors tell the Anti-Lock Brake (ABS) Module how fast the vehicle is moving. The Output Shaft Speed Sensor tells the Transmission Control Module (TCM) how fast output shaft of the transmission is actually spinning. This information is compared between the PCM and TCM modules. If the Output Shaft Speed sensor does not match the vehicle speed sensor information, the PCM will set code P215C.
OBD-II Code Transmission may not shift properly is defined as a Output Shaft Speed - Wheel Speed Correlation
