U1424 on 2022-2025 Jeep Grand Wagoneer — Implausible Engine Torque Signal Received
1 vehicles · 1 makes
Most Reported On
U1424 is an OBD-II diagnostic trouble code meaning “Implausible Engine Torque Signal Received.” U1424 is a manufacturer-specific network/communication code reported on Ford and Chrysler-family vehicles. It indicates that a control module received an engine torque value over the data bus that is implausible (out of expected range or inconsistent with other inputs). This often points to a software calibration mismatch or a sensor/module sending bad data rather than a single failed part. On many vehicles the fix is a PCM/module software update, though wiring and sensor faults can also cause it. This code is most commonly reported on 2022-2025 Jeep Grand Wagoneer.
