7. Install breakout cable. Place
ignition switch to ON position
and check intake manifold
pressure sensor signal voltage.
Check voltage between lead B
and C of breakout cable.
Voltage should be 0.42-0.58V.
If voltage is not as specified,
proceed with the following steps.
8. Place ignition switch to OFF
position. Disconnect intake
manifold pressure sensor from
engine harness and disconnect
sensor harness from engine
ECU.
a. Measure resistance from
sensor harness connector pin
39
to
chassis
ground.
Resistance should be more
than 100k ohms.
If resistance is not as specified,
notify SRA.
