Chevrolet Spark transmission pressure sensor repair issue with code P0841 on Chevrolet Spark

Some Chevrolet Spark owners report experiencing issues related to trouble code P0841, which indicates a problem with the transmission fluid pressure sensor circuit. This code is triggered when the input from the sensor falls outside the expected range set by the Powertrain Control Module (PCM). Common causes of this trouble code include a faulty transmission fluid pressure sensor, wear affecting the sensor's functionality, and problems with wiring or connectors associated with the sensor. To address these issues, some owners find it necessary to visually inspect the wiring harness and connectors, check the transmission fluid level and condition, and potentially replace the fluid. The repair process may involve replacing the faulty sensor, checking for damage or corrosion in the wiring, and evaluating the Transmission Control Module (TCM) for updates or connectivity issues. Ensuring that the transmission fluid is at the correct level and in good condition is crucial for resolving the P0841 code and related transmission pressure sensor concerns.
