(22) 5.9L V-8 Engine With Two Wheel Drive
(2WD):
(a) This engine/transmission is equipped with 4
oxygen sensors. Verify both pre-catalyst and post-
catalyst oxygen sensor wire connectors (before and
after catalytic convertor) are firmly connected to
sensors (Fig. 11). Inspect sensors and connectors
for damage.
(b) Verify left and right oxygen sensor wire con-
nectors (at exhaust downpipes) are firmly con-
nected to sensors (Fig. 12). Inspect sensors and
connectors for damage.

(23) Inspect for pinched or leaking fuel tubes.
Inspect for pinched, cracked or leaking fuel hoses.
(24) Inspect for exhaust system restrictions such
as pinched exhaust pipes, collapsed muffler or
plugged catalytic convertor.
(25) If equipped with automatic transmission, ver-
ify electrical harness is firmly connected to park/neu-
tral switch. Refer to Automatic Transmission.
(26) Verify electrical harness is firmly connected to
rear wheel speed sensor. Verify rear wheel speed sen-
sor is firmly attached to rear axle with proper air
gap. Refer to 5, Brakes for information.
(27) If equipped with 4–wheel antilock brake sys-
tem, verify electrical harness is firmly connected to
each front wheel speed sensor. Verify both front
wheel speed sensors are firmly attached. Refer to 5,
Brakes for information.
(28) Verify fuel pump/gauge sender unit wire con-
nector is firmly connected to harness connector.
(29) Inspect fuel hoses at fuel pump/gauge sender
unit for cracks or leaks.
(30) Inspect transmission torque convertor housing
(automatic transmission) or clutch housing (manual
transmission) for damage to timing ring on drive
plate/flywheel.
(31) Verify battery cable and solenoid feed wire
connections to starter solenoid are tight and clean.
Inspect for chaffed wires or wires rubbing against
other components.
