Default fuel pressure sensor

Where is the fuel pressure sensor located on a 98 d1?

I have something sucking voltage from my TPS and a wire diagram I was looking at shows fuel pressure sensor tied in with it

Now the rave shows the wire splits off from the TPS at s148 goes through c1026 and c2082 ending at c407 and says not used this is circuit diagram 5 section A3 electrical manual

In the shop mech program my friend showed me same diagram and it showed hooked to a fuel pressure sendor

Providing your '98 has AEL the Fuel Pressure Sensor is apart of the fuel pump.


RAVE has the sensor as X320 (top of fuel tank). The connector is C484. Page 69 under COMPONENT LOCATION VIEWS.

The diagram A3-5 your friend showed you is correct.


From PIN 1 (S148) in the TPS (X171) circuit terminates at the Fuel Pressure Sensor(X320) in Pin 3(C484)


You'll get it sorted, Good Luck!

Fixed it that sensor was broken water got in and shorted/ corroded it so it was stealing my TPS supply voltage, guess I needs new fuel sendor
