Repair Procedures: Inspection

[Fuel sender] 

1. Turn the ignition switch OFF, and then remove battery (-) cable.
2. Remove the fuel pump assembly.
3. Using an ohmmeter, measure the resistance between terminals 1 and 6 of sender connector (A) at each float level.

   Pin No.	Description
   1	Fuel sender ground
   2	Fuel pressure sensor (FPS) signal input
   3	CAN [High]
   4	Fuel pressure sensor (FPS) power supply (+5V)
   5	Fuel pressure sensor (FPS) ground (-)
   6	Fuel sender signal
   7	-
   8	CAN [Low]
   9	Ground
   10	Battery power (B+)

4. Also check that the resistance changes smoothly when the float is moved from "E" to "F".
