- [11029625](https://open.wenmarpro.com/bulletins/11029625), 2026-03-05: Some vehicles may display some \(or all\) of the following symptoms: • Check engine light on with DTC P061B • Light increase in engine rpms during acceleration • Transmission will not shift past 4th gear • Various U codes \(U0401 ABS, U0401, U0415 FSC, U0301, U0316 SBS/MRCC, U0442 TCM\) may be set
- [10218722](https://open.wenmarpro.com/bulletins/10218722), 2022-09-06: Some vehicles may experience a lack of power and the check engine light on with DTC P061B:00 stored in PCM memory under one of the following conditions \(A or B\). \- DTC P061B:00 \- \[PCM\] Internal control module torque calculation performance problem. Condition Condition Description A When cranking is interrupted \(likely occurs when the brake pedal is released during cranking\) B When accelerating from 1300\-1600 rpm with wide open throttle Due to an improper control logic of the PCM, the engine torque calculation error detection is too sensitive. To eliminate this concern, the PCM software has been modified.
