The P215B: Vehicle Speed – Output Shaft Speed Correlation refers to a fault where there is a mismatch between the vehicle speed and the output shaft speed readings. This issue can be caused by a faulty output shaft speed sensor, calibration issues, or transmission problems that affect the speed correlation.
P215B – Quick Overview
| Code | Information |
|---|---|
| Meaning | P215B: Vehicle Speed – Output Shaft Speed Correlation |
| Is it serious? | Yes, this can lead to transmission performance issues and may affect vehicle shifting. |
| Possible causes | – Mismatch between vehicle speed and output shaft speed – Faulty output shaft speed sensor – Calibration issues or transmission problems |
| How to diagnose? | – Compare vehicle speed with output shaft speed readings – Test the output shaft speed sensor for faults – Check for transmission issues and calibration |
P215B Meaning
The P215B: Vehicle Speed – Output Shaft Speed Correlation code indicates that the vehicle’s speed and the output shaft speed (usually measured within the transmission) are not aligning as expected. This can be caused by problems with the sensor that measures the output shaft speed or issues within the transmission itself. A faulty correlation can lead to problems with shifting or drivability.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to see if there are additional related codes, which may help in diagnosing the root cause. | OBD-II Scanner |
| Compare Vehicle and Output Shaft Speeds | Use diagnostic software to compare the vehicle speed reading with the output shaft speed. If the readings are inconsistent, it indicates a correlation issue. | Diagnostic Software, OBD-II Scanner |
| Inspect Output Shaft Speed Sensor | Inspect the output shaft speed sensor for signs of damage or wear, and test its functionality with a multimeter. | Multimeter, Safety Gloves |
| Check for Transmission Issues | Inspect the transmission for mechanical problems that may affect the output shaft speed, such as damaged components or wear. | Flashlight, Wrenches |
| Check Sensor Calibration | Verify the calibration of the output shaft speed sensor. If miscalibrated, recalibrate the sensor according to manufacturer specifications. | Calibration Tool (if needed) |
| Repair or Replace Faulty Components | Repair or replace any faulty components, such as the output shaft speed sensor or damaged transmission parts. | Replacement Parts, Tools |
| Clear the Code and Test Drive | Clear the P215B code using an OBD-II scanner after repairs, and perform a test drive to ensure the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure that the P215B code has not returned. | OBD-II Scanner |
