P061E

Control Module Brake Signal Performance

P061E is a generic OBD-II powertrain diagnostic trouble code: Control Module Brake Signal Performance. It is logged by the engine control unit when the powertrain monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.

What P061E means

P061E is set when the powertrain control module (PCM) detects that the internally calculated or monitored throttle position does not agree with the expected value during a self-test or cross-check routine. The ECM continuously compares redundant throttle position signals and internal processor calculations to verify consistent results.

This code is closely tied to electronic throttle control (ETC) systems where the PCM uses multiple internal processing paths to validate accelerator pedal and throttle body sensor data. A disagreement beyond calibrated thresholds triggers this fault.

When this DTC is active the PCM may reduce engine power or engage a reduced-power (limp) mode to protect the drivetrain. Common triggers include internal processor faults, software calibration mismatches, or intermittent sensor signal corruption reaching the control module's processing core.

Common causes

Most-frequently reported root causes when P061E is logged.

  • 1
    Internal PCM processor calculation error or memory corruption affecting throttle position monitoring.
  • 2
    Faulty electronic throttle body sending inconsistent position feedback to the PCM.
  • 3
    Wiring fault (short, open, or high resistance) in the throttle position sensor circuit.
  • 4
    Corrupted PCM calibration or software requiring reflash.
  • 5
    Intermittent power supply or ground issue to the PCM causing processor errors.
  • 6
    Failed or degraded throttle position sensor within the throttle body assembly.
  • 7
    PCM hardware failure causing internal signal cross-check to fail.

Symptoms drivers notice

Malfunction indicator lamp (MIL) illuminated.
Reduced engine power or limp-home mode active.
Hesitation or unresponsive throttle during acceleration.
Engine may idle roughly or stall in severe cases.

How to diagnose P061E

A typical diagnostic flow when this code is present.

  1. 1
    Connect a scan tool and record all stored DTCs and freeze frame data before clearing codes.
  2. 2
    Check for related throttle position sensor codes (P0120-P0124, P0220-P0224) that may indicate a sensor fault rather than a PCM fault.
  3. 3
    Inspect throttle body wiring harness and connectors for damage, corrosion, or backed-out pins.
  4. 4
    Use live data to compare TP sensor 1 and TP sensor 2 values for agreement across the full throttle sweep.
  5. 5
    Check PCM power supply and ground circuits for proper voltage and low resistance.
  6. 6
    If wiring and sensors check out, verify current PCM software level and reprogram if a relevant calibration update is available.
  7. 7
    If fault persists after reprogramming, suspect PCM hardware failure and consider replacement.

Frequently asked questions

Can I drive with P061E active?

Short-distance driving may be possible if the vehicle is only in limp mode, but continued operation risks further damage. Have the vehicle diagnosed promptly.

Does P061E always mean the PCM needs replacing?

No. In many cases a PCM software reflash or a faulty throttle body sensor is the root cause. Always diagnose thoroughly before condemning the PCM.

Will clearing the code fix the problem?

Clearing the code without addressing the root cause will result in it returning. Use freeze frame and live data to identify the underlying fault first.

Is P061E related to the accelerator pedal sensor?

Indirectly yes. The PCM monitors both accelerator pedal position and throttle position as part of ETC monitoring; a fault in either circuit can contribute to this code.

Disabling P061E in software

RaceTune can permanently disable P061E — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.

Permanent
The monitor is disabled in the ECU itself — not just cleared. It cannot return.
Tailored to your file
Each patch is matched to your specific software version — never a one-size-fits-all file.
Reversible
The original file is always preserved. Reflash the stock to return the ECU to factory state.

Software modifications affect emissions compliance and are not road-legal in many jurisdictions. RaceTune service files are intended for motorsport, off-road, and export use.
