What causes code P0841?
There may be one or more causes for the P0841 code. One may be a faulty electronic pressure control solenoid. Another could be that there is something wrong with your transmission fluid pressure sensor, or that your vehicle has hydraulic blockages inside the internal transmission fluid passages.
What is a transmission fluid sensor?
Description. Thermometrics Transmission Fluid Temperature Sensor (TFT) measures the temperature of transmission fluid. It provides input to the control module to modify shift patterns for smoother shifting in automatic transmissions, and also provides over-temperature protection by locking the torque convertor.
What does the p0842 code on a transmission mean?
All our repairs are backed by our 12-month / 12,000-mile warranty. The P0842 code indicates that there has been an abnormally high voltage reading from the transmission fluid pressure sensor circuit. Other shift solenoid, transmission slippage, lock up, gear ratio, or torque converter clutch codes are often stored in the PCM with the P0842 code.
