P061BInternal Control Module Torque Calculation Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Electronic throttle systems run a second, independent calculation on the same processor (level 2, at Ford 'IPC – independent plausibility check') that recomputes driver demand, permitted and actual torque and their inputs, and compares them with the main software. P061B means the torque calculation itself is inconsistent: main software and monitoring compute the torque differently. On Ford petrol engines it sets within 1 s with the check engine and wrench lamps and blocks the catalyst monitor. On Ford's 2023 diesel torque equals injected fuel, so P061B checks the injection control instead – energising times outside 10–850 ms, more than 127.2 µs between programmed and actual, or more than 5 mg difference in quantity correction (5 s). Software updates fixed it on Chrysler's 3.0 L EcoDiesel and the Ram 6.7 L Cummins; on the Ford Five Hundred it came with idle codes and a dirty throttle body.
- What you may notice
- Check engine light and wrench lamp
- Reduced power or limp mode
- Fluctuating idle (Ford petrol with dirty throttle)
- Sometimes only the lamp
- Likely causes
- LikelyEngine module software or calibration fault (update available)
- PossibleDirty throttle or air path, idle adaptation at its limit (petrol)
- PossibleVoltage dips, poor ground or supply at the module
- RareInjector quantity deviation pushing the zero-fuel calibration out of range (diesel)
- RareInternal defect of the engine module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
