DTC Advanced Diagnostics: P215C

DTC P215C:Output Shaft (Countershaft) Speed/Vehicle Speed Correlation

General Description

The powertrain control module (PCM) monitors the speed difference of the wheel speed sensors and output shaft (countershaft) speed sensor to detect malfunctions. If there is a difference between the speed of the output shaft (countershaft) speed sensor and the average of left and right wheel speed sensors for a specified duration, the PCM detects a malfunction and stores a DTC.

Monitor Execution, Sequence, Duration, DTC Type

Execution	Continuous
Sequence	None
Duration	6.0 seconds or more
DTC Type	Two drive cycles, MIL on

Enable Conditions

Condition
Vehicle	Running

Malfunction Threshold

The difference between the speed of the output shaft (countershaft) speed sensor and the average of left and right wheel speed sensors is 1.9 mph (3 km/h)

6% or more for at least 6.0 seconds.

Possible Cause

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

	Output shaft (countershaft) speed sensor
	Left front wheel speed sensor failure
	Right front wheel speed sensor failure
	PCM internal circuit malfunction

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool clear command or by disconnecting the 12 volt battery.
