Transmission Fluid Pressure Sensor Switch A Circuit

This information is relayed to the transmission control module tcm where it is used to determine control of various outputs such as the pressure control solenoids.

Transmission fluid pressure sensor switch a circuit. The p0989 code is a generic obd ii trouble code that detects a transmission fluid pressure sensor e circuit abnormality. What the p0989 code means. This generic powertrain engine diagnostic trouble code typically applies to all obd ii equipped vehicles including but not limited to jeep dodge mazda nissan honda gm etc. An automatic transmission needs a certain amount of hydraulic pressure in order to move gears around and propel you down the road.

What does that mean. The transmission fluid pressure tfp sensor or switch is used to determine internal transmission pressure. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. How to repair p0843 code transmission fluid pressure sensor switch a circuit high the torque converter clutch tcc release switch is part of the automatic transmission fluid pressure tfp manual valve position switch.

The tfps or transmission fluid pressure sensor switch is usually attached to the valve s side inside the transmission. What does that mean. This generic powertrain engine diagnostic trouble code typically applies to all obd ii equipped vehicles including but not limited to chevrolet acura honda saturn jeep toyota etc. Transmission fluid pressure sensor switch a circuit low.

The transmission control module tcm monitors the transmission fluid pressure sensor switch signal. P0842 is a diagnostic trouble code dtc for transmission fluid pressure sensor switch a circuit low. The p0989 trouble code notes a problem with the transmission fluid pressure sensor e circuit. In some cases it s screwed to the side of the transmission case body itself.

The tcm sets the obdii code when the transmission fluid pressure sensor switch is not to factory specifications. If transmission fluid pressure switch a 2nd clutch is off while driving the vehicle with the rotation speed ratio of the input output pulses is that of 2nd gear the pcm detects a transmission fluid pressure switch a 2nd clutch failure and stores a diagnostic trouble code dtc.
