- [11035232](https://open.wenmarpro.com/bulletins/11035232), 2026-07-27: Some 2025\-2026 Bronco/Ranger vehicles may exhibit an illuminated powertrain malfunction \(wrench\) indicator with diagnostic trouble codes \(DTC\) P2122, P2123, P2127, P2128, and/or P2138 stored in the powertrain control module \(PCM\). The vehicle may or may not exhibit a perceived lack of power intermittently. This may be due to an issue with the following connectors associated with the accelerator pedal position \(APP\) sensor circuits: \-C115B \-C175B \-C2040 Replacement of the accelerator pedal may not resolve this concern. Perform a wiggle test of the connectors while the engine is at normal operating temperature. Perform a visual inspection of the connectors as well as a terminal fit test using the appropriately sized flex probe. Repair as necessary. Refer to Wiring Diagram Cell 005. If no concerns are found, refer to Workshop Manual \(WSM\), Section 310\-02 for normal diagnostics.
