DIAGNOSIS A N D T E S T I N G (Continued)
The sensor is located on the top of cylinder block
near the rear of right cylinder head (Fig. 25).
(1) Near the rear of the intake manifold, discon­
nect sensor pigtail harness connector from main wir­
ing harness.

(2) Place an ohmmeter across terminals B and C
(Fig. 26). Ohmmeter should be set to lK-to-lOK scale
for this test. The meter reading should be open (no
resistance). Replace sensor i f a low resistance is indi­
cated.

To perform a complete test of this sensor and its
circuitry, refer to the DRB scan tool.. Also refer to the
appropriate Powertrain Diagnostics Procedures man­
ual. To test the' sensor only, refer to the following:
(1) Raise and support the vehicle.
(2) Disconnect the sensor pigtail harness from the
main engine wiring harness connector.
(3) Place an ohmmeter across terminals B and C
(Fig. 26). Ohmmeter should be set to lK-to-lOK
scale for this test. The meter reading should be
open (no resistance). Replace sensor i f a low resis­
tance is indicated.
