What Does P061E Mean?
The PCM/ECM has detected an internal performance error related to the brake signal input. The module's internal check of the brake pedal signal does not match expected behavior — for example, the brake switch signal may be stuck on, stuck off, or not correlating with other vehicle data like deceleration or stop lamp circuit status. This can affect cruise control operation, torque converter clutch engagement, and shift quality on automatic transmissions.
Common Causes
35%
Faulty brake light switch out of adjustment or internally failed
25%
PCM/ECM software calibration issue with brake signal rationality check
20%
Wiring issue in brake signal circuit between switch and PCM
12%
Blown brake light fuse or burned-out brake light bulbs affecting circuit feedback
8%
Internal PCM failure in brake signal processing circuit
Diagnostic Steps
1
Monitor the brake switch PID on the scan tool while pressing and releasing the brake pedal. The signal should toggle cleanly between on and off with no intermittent readings.
2
Check brake light operation — have an assistant press the brake pedal while you verify all brake lights illuminate. Check the brake light fuse if none work.
3
Inspect the brake light switch at the brake pedal bracket. Verify proper adjustment — the switch should activate within the first 1/4 inch of pedal travel. Check the switch connector for corrosion or loose pins.
4
Using a multimeter, backprobe the brake switch circuit at the PCM connector. Verify the signal changes state when the brake pedal is pressed (typically 0V to 12V or vice versa).
5
Check for TSBs related to PCM software updates for brake signal rationality. Perform a reflash if available.

The most common cause of P061E (Internal Control Module Brake Signal Performance) is: Faulty brake light switch out of adjustment or internally failed
Typical repair costs for P061E range from $30 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This code can disable cruise control and affect transmission shift quality. If the brake lights are not functioning due to this issue, other drivers will not see your braking, which is a serious safety hazard. Verify brake light operation immediately. If brake lights work, the vehicle is safe to drive but should be diagnosed soon.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P061E to identify the root cause.
