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.
How do you fix low transmission pressure?
What Repairs Will Fix P0868?
- Change the transmission fluid and filter.
- Repair transmission fluid leaks.
- Repair or replace damaged wiring and sensors on the transmission wiring harness.
- Replace the transmission pump.
- Replace transmission fluid pressure sensor.
- Replace transmission fluid temperature sensor.
Where is the transmission pressure sensor located?
The Transmission Fluid Pressure Sensor/Switch (TFPS) is usually found attached to the side of the valve body inside the transmission, although sometimes it may be found screwed into the side of the transmission case/body itself.
How much does it cost to replace transmission pressure switch?
Replacing your transmission oil pressure switch can cost anywhere between $170 and $300, depending on the make and model of your vehicle, the cost of parts and the cost of labor.
What causes low transmission pressure?
Insufficient transmission fluid levels due to leaks in the system. Slipping or otherwise malfunctioning transmission. Malfunctioning transmission high pressure pump. Defective transmission temperature sensor.
What does a transmission fluid pressure sensor do?
The transmission oil pressure sensor’s primary function is to relay information to the ECM that regulates control of the transmission. However, if the switch is damaged or not sending information correctly to the ECM, the transmission may default into “limp” mode.

How do I fix code P0842?
What repairs can fix the P0842 code?
- Replacing the pressure control solenoid.
- Refilling, or flushing and replacing, the old transmission fluid.
- Clearing blocked transmission fluid passages.
- Addressing any mechanic internal transmission failures.
- Replacing a faulty PCM or TCM, in rare cases.
How much does it cost to replace a pressure control solenoid?
Depending on the make, model, and year of your vehicle, transmission solenoid replacement costs can vary. In general, a single faulty transmission solenoid replacement costs approximately $250. Replacing the entire solenoid pack can cost around $400.
How much does it cost to replace a sensor in the transmission?
The average cost for transmission position sensor replacement is between $251 and $301. Labor costs are estimated between $138 and $174 while parts are priced between $113 and $128. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
Can a sensor cause transmission problems?
The Vehicle Speed Sensor measures vehicle speed. If it fails or malfunctions the automatic transmission may not operate properly. It may also cause the automatic transmission to go into failsafe mode making it appear that the problem is more severe than it actually is.
How long does it take to replace transmission sensor?
If you get a professional to do the job, then it should take about 2 to 3 hours to replace the range sensor. It may take longer to fix if the sensor is located on the inside of the transmission box as the mechanic will have to disassemble it and put it back together.
