9.5.10 - Pressure Sensor Input Power Check
Disconnect the pressure sensor from the pressure sensor harness. Connect one end of the pressure sensor breakout
harness diagnostic tool into the pressure sensor shroud connector. Connect the other end into the pressure sensor
harness tower connector.
[Figure 61]
- Use a voltmeter to observe that there is 13.5 VDC between the Red and Black wire on the pressure
sensor breakout harness with the engine running, or 12.0 VDC without the engine running.
Be sure the polarity is accurate by observing that there is positive voltage when the Red (positive) probe is connected
to Red pressure sensor breakout harness wire and the Black (negative) probe is connected to Black pressure sensor
breakout harness wire.
If no voltage is present:
• Check the fuse located at the battery.
• Check the battery connections.
• Check the condition of the battery.
• Check the condition of the alternator.
Figure 61: Pressure Sensor Input Power Check
Make sure the Breakout Harness Diagnostic Tool is properly connected between the Pressure
Sensor shroud connector and the Pressure Sensor harness tower connector. (See
Figure 61
).
A poorly connected diagnostic tool is a frequent issue when trying to obtain voltage readings.
