Why is my transmission fluid pressure sensor low?

Why is my transmission fluid pressure sensor low?

Typically the causes for this code to set are: Short to ground in the signal circuit to the TFPS sensor – possible Failed TFPS Sensor / internally shorted – likely Failed PCM – unlikely (programming required after replacement) A good starting point is always to check for technical service bulletins (TSB) for your particular vehicle.

What is the diagnostic code for transmission fluid pressure?

P0842 is a diagnostic trouble code (DTC) for “Transmission Fluid Pressure Sensor/Switch A Circuit Low”.

How to connect transmission fluid pressure sensor G circuit?

Connect the red lead of the Digital Voltmeter to the signal terminal at the TFPS sensor wiring harness connector. Turn Key On Engine Off. Check manufacturer’s specifications; voltmeter should read either 12 volts or 5 volts. Wiggle the connections to see if they change.

What is the function of the transmission oil pressure sensor?

The transmission oil pressure sensor’s primary function is to relay information to the ECM that regulates control of the transmission.

Where are the sensors on a Honda Accord?

Fuel Tank Pressure Sensor Air Temperature Sensor ( Ambient / Intake 1 Manifold Pressure/Vacuum Sensor Power Steering Pressure Switch Throttle Position Sensor Transmission Position Sensor/Switch Variable Valve Timing Actuator Position Sensor Variable Valve Timing Pressure Switch Camshaft Position Sensor Crankshaft Position Sensor

What happens if the transmission oil pressure sensor is damaged?

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.

What is the code for Honda Pilot Oil pressure switch?

Thanks to this forum for all this advice when the CEL showed this code on my recently purchased 2011 Honda Pilot. Here’s my chance to give back for all the 2009-2011 Pilot owners with a flashing “D” and DTC 0847. The problem is purely electrical so that’s good news. The other good news is that Honda redesigned the part.

Connect the red lead of the Digital Voltmeter to the signal terminal at the TFPS sensor wiring harness connector. Turn Key On Engine Off. Check manufacturer’s specifications; voltmeter should read either 12 volts or 5 volts. Wiggle the connections to see if they change.
