O2 SENSOR (Continued)
INSTALLATION
INSTALLATION - UPSTREAM 1/1, 2/1
The engines uses two heated oxygen sensors, one
in each exhaust manifold.
(1) After removing the sensor, the exhaust mani-
fold threads must be cleaned with an 18 mm X 1.5 +
6E tap. If reusing the original sensor, coat the sensor
threads with an anti-seize compound such as Loctite
771- 64 or equivalent. New sensors have compound
on the threads and do not require an additional coat-
ing. Tighten the sensor to 28 N·m (20 ft. lbs.) torque.
(2) Connect the heated oxygen sensor electrical
connector.
(3) Install the negative battery cable.

INSTALLATION - DOWNSTREAM 1/2, 2/2

The O2 sensor are located at the outlet ends of the
catalytic converter.
Threads of new oxygen sensors are factory coated
with anti-seize compound to aid in removal. DO
NOT add any additional anti-seize compound to
the threads of a new oxygen sensor.
(1) Install the O2 sensor. Tighten to 28 N·m (20 ft.
lbs.) torque.
(2) Connect the O2 sensor wire connector.
(3) Lower the vehicle.
(4) Install the negative battery cable.
SHORT RUNNER VALVE
DESCRIPTION
It is a electrical actuator attached to the intake
manifold (Fig. 23).

OPERATION

The SRV (Fig. 23) system operates under WOT
conditions above 5000 rpm to maximize engine per-
formance. When actuated by the PCM, the SRV sole-
noid energizes, allowing mechanical linkage to
redirect the intake air flow to six short runners. The
PCM looks for a current spike when actuating the
solenoid. If the spike is not present, the PCM sets
the DTC.

REMOVAL - 3.5L

(1) Remove the negative battery cable.
(2) Remove link.
(3) Remove electrical connector.
(4) Remove 3 bolts.
(5) Remove valve (Fig. 24).
