1. Frame harness connector
2. 1.5 V dry cell battery
C. Connect a 1.5 VDC dry cell battery across the signal (+) pin C and ground
(−) pin B of the frame wire harness connector. A fully charged battery
should produce a pressure reading of approximately 8960 kPa (1300
psi) on the InfoCenter Display. This confirms the integrity of the circuit
ground and signal wires.
D. Use a multimeter set to DC voltage and check for approximately 5 VDC
across the supply (+) pin A and ground (−) pin B of the frame wire
harness connector. This confirms the integrity of the circuit supply and
signal wires.
E. Turn the key switch to OFF.
4. Test the pressure sensor:
A. Remove the pressure sensor.

1. Pressure sensor
2. 4.5 to 5.5 VDC power supply
B. Connect a 4.5 to 5.5 VDC power supply to the supply (+) pin A and
ground (−) pin B of the sensor.
C. Connect a multimeter set to DC voltage to the signal (+) pin C and ground
(−) pin B of the sensor. A small amount of voltage (0.5 VDC) should be
present on the multimeter display.
5. Replace pressure sensor if necessary. Apply thread sealant to the sensor
threads prior to installation and tighten to 20 N∙m (15 ft-lb).
6. Connect the frame wire harness to the pressure sensor after testing.
