(1)Before installing an injector the rubber O-ring must be lubricated with a drop of clean engine oil to aid in installation.
(2)Install injector clip by sliding open end into top slot of the injector. The edge of the receiver cup will slide into the side slots of clip (Fig. 19).
(3)Install injector top end into fuel rail receiver cap. Be careful not to damage O-ring during installation (Fig. 19).
(4)Repeat steps for remaining injectors.
(5)Connect fuel injector wiring.

The alignment of the MAP sensor is critical to the sensors performance. The top of the sensor is marked This Side Up (Fig. 20).
(1)Disconnect electrical connector from MAP sen-
sor.
(2)Remove sensor by unscrewing from the intake manifold (Fig. 20).
(3)Reverse the above procedure for installation.
Fig. 21 Canister Purge Solenoid
(2)Depress tab on top of solenoid and slide the solenoid downward out of mounting bracket.
(3)Reverse above procedure for installation.
(1)Remove air cleaner duct from engine controller.
(2)Remove battery.
(3)Remove engine controller mounting screws (Fig.
22).

(4)Remove 60-way electrical connector from engine controller.
(5)Reverse the above procedure for installation.
(1) Disconnect crankshaft timing sensor electrical connector from the wiring harness connector (Fig. 23).

(2)Remove crankshaft timing sensor retaining bolt.
(3)Pull crankshaft timing sensor straight up out of the transaxle housing.
If installing the original sensor, clean off the old spacer on the sensor face. A NEW SPACER must be attached to the sensor face before installation. If the sensor is being replaced, confirm that the paper spacer is attached to the face of the new sensor (Fig. 24).
Fig. 24 Crankshaft Sensor and Spacer
(1)Install sensor in transaxle and push sensor down until contact is made with the drive plate.
While holding the sensor in this position, and install and tighten the retaining bolt to 12 NIm (105 in. lbs.) torque.
(2)Connect crankshaft timing sensor electrical connector to the wiring harness connector.
(1)Disconnect camshaft reference sensor electrical connector from the wiring harness connector (Fig. 25).
(2)Loosen camshaft timing sensor retaining bolt enough to allow slot in sensor to slide past the bolt.
Fig. 25 Camshaft Sensor
(3) Pull sensor up out of the chain case cover. Do not pull on the sensor lead. There is an O-ring on the sensor case. The O-ring may make removal difficult. A light tap to top of sensor prior to removal may reduce force needed for removal.
If installing the original sensor, clean off the old spacer on the sensor face. A NEW SPACER must be attached to the face before installation. Inspect O-ring for damage, replace if necessary. If the sensor is being replaced, confirm that the paper spacer is attached to the face and O-ring is positioned in groove of the new sensor (Fig. 26).
Fig. 26 Camshaft Sensor
(1)Apply a couple drops of clean engine oil to the O-ring prior to installation. Install sensor in the chain case cover and push sensor down until contact is made with the cam timing gear. While holding the
sensor in this position, install and tighten the retaining bolt 12 NIm (105 in. lbs.) torque.
(2)Connect camshaft reference sensor electrical connector to harness connector. Position connector away from the accessory belt.

The oxygen sensor is installed in the exhaust manifold (Fig. 27).
Fig. 27 Oxygen SensorÐ3.3L Engine
CAUTION: Do not pull on the oxygen sensor wire when disconnecting the electrical connector.
WARNING: THE EXHAUST MANIFOLD MAY BE EXTREMELY HOT. USE CARE WHEN SERVICING THE OXYGEN SENSOR.
(1)Disconnect oxygen sensor electrical connector (Fig. 28).
(2)Remove sensor using Tool C-4907 (Fig. 29). When the sensor is removed, the exhaust manifold
threads must be cleaned with an 18 mm X 1.5 + 6E tap. If using original sensor, coat the threads with Loctite 771-64 anti-seize compound or equivalent. New sensors are packaged with compound on the threads and do not require additional compound. The sensor must be tightened to 27 NIm (20 ft. lbs.) torque.
