P0C60Drive Motor B Position Sensor Circuit B Range/Performance

Q: What does code P0C60 mean?

Drive Motor B Position Sensor Circuit B Range/Performance. P0C60 indicates that the hybrid or electric vehicle's control module has detected an out-of-range or erratic signal from the position sensor circuit B of drive motor B, which is the motor responsible for propulsion or regeneration. The computer compares the sensor's reported position against expected values and sets this code when the signal falls outside the acceptable performance window.

Symptoms you may notice

Illumination of the hybrid system warning light or service vehicle soon light
Reduced power or limp mode, often limiting vehicle speed
Hesitation or shuddering during acceleration or regenerative braking
Inability to start the vehicle or engage drive
Often no symptoms besides the warning light

Common causes, most likely first

Faulty motor position sensor B (internal failure or contamination)
Damaged or corroded wiring harness or connector at the sensor or control module
Poor electrical connection due to loose pins or water intrusion
Failed motor control module or inverter assembly
Mechanical damage to the motor resolver or tone ring
Software calibration error in the control module

How to diagnose and fix it

Inspect the sensor connector and wiring for corrosion, chafing, or loose pins
Measure sensor resistance and compare to manufacturer specifications
Check for proper sensor supply voltage and ground at the connector
Perform a wiggle test on the harness while monitoring sensor data
Replace the motor position sensor if electrical checks fail
Reprogram or recalibrate the control module if a software update is available
Replace the motor control module or inverter only after confirming all other circuits are good

Before you replace the drive motor

A loose or corroded connector at the motor position sensor is a frequent cause that mimics a failed sensor, so always inspect the pins and seals first.
The code can be set by a momentary glitch in the signal due to electrical interference from other high-voltage components, not a hard failure.
Some vehicles require a relearn or calibration procedure after sensor replacement, and skipping it will cause the code to return immediately.
A failing 12-volt battery or poor ground can cause erratic sensor readings that set this code without any fault in the sensor itself.
The position sensor circuit B may share wiring with other sensors, so a short in a related circuit can trigger this code even if the sensor is good.

Can I keep driving with P0C60?

Do not continue driving with this code set, as the vehicle may enter limp mode or lose propulsion without warning; have it diagnosed and repaired by a qualified technician before resuming normal use.
