CAUTION: Prior to removal of the camshaft position sensor (CMP sensor) (12126) , set cylinder No.1 to zero degrees top dead center (TDC) of compression stroke. Then note the position of the camshaft position sensor electrical connector. The installation procedure requires the connector be located in the same position. Removal 1. Disconnect battery ground cable (14301). Refer to Section 14-01. 2. Disconnect fuel charging wiring connector from camshaft position sensor. 3. Remove camshaft position sensor retaining screws and camshaft position sensor from camshaft position sensor housing. 4. If removing camshaft position sensor housing from the cylinder block (6010), proceed with Removal Step 5. If not removing camshaft position sensor housing, proceed to Step 6 of the installation procedures. 5. Remove hold-down clamp (12270) (bolt and washer assembly). 6. NOTE: Remove the oil pump intermediate shaft (6A618) with the camshaft position sensor housing. Remove camshaft position sensor housing from cylinder block. Installation 1. CAUTION: If the replacement camshaft position sensor housing does not contain a plastic locator cover tool, a special service tool must be obtained prior to installation of the replacement camshaft position sensor. Failure to follow this procedure will result in improper camshaft position sensor alignment. This will result in the ignition fuel system being out of time with the engine, possibly causing engine damage. NOTE: For 3.0L engines, use Syncro Positioning Tool 303-589. For 3.8L engines, use Syncro Positioning Tool 303-562 (T96T-12200-A). If the plastic locator cover tool is not attached to the replacement camshaft position sensor housing, attach syncro positioning tool as follows: a. Engage camshaft position sensor housing vane into the radial slot of the tool. b. Rotate tool on camshaft position sensor housing until tool boss engages notch in camshaft position sensor housing. 2. Transfer oil pump intermediate shaft from old camshaft position sensor housing to replacement camshaft position sensor housing. 3. Install camshaft position sensor housing so drive gear engagement occurs when arrow on syncro positioning tool is pointed approximately as shown in the illustrations. This step will locate camshaft position sensor electrical connector in the pre-removal position. 4. Install hold-down clamp (washer and bolt assembly) and tighten bolt to 20-30 Nm (15-22 lb-ft). 5. Remove syncro positioning tool. 6. CAUTION: If camshaft position sensor electrical connector is not positioned properly, DO NOT reposition the connector by rotating the camshaft position sensor housing. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the camshaft position sensor housing and repeat installation procedure, beginning with Step 1. Install camshaft position sensor and retaining screws. On 3.0L engine, tighten screws to 2.5-3.5 Nm (23-30 lb-in). On 3.8L engine, tighten screws to 4.5-7 Nm (40-61 lb-in). 7. Connect fuel charging wiring connector to camshaft position sensor. 8. Connect battery ground cable. Refer to Section 14-01. Camshaft Position Sensor—3.0L Engine

CAUTION: To prevent damage to valves and pistons, do NOT rotate the crankshaft and / or camshaft(s) when removing the timing chain(s) and installing the cylinder heads. Because this is not a free-wheeling engine, if it has “jumped time,” there will be damage to the valves and / or pistons which will require the removal of the cylinder heads. The cam sprocket should be disassembled from the camshaft only when one of the components must be replaced. 1. Remove all necessary components to access the timing chains. 2. Rotate the engine to No. 1 TDC. 3. Install No. 6009 (511532) on flats of the camshaft as shown to prevent accidental rotation of the camshafts. 4. Perform camshaft service as required. 5. Refer to the vehicle service manual for the correct camshaft-to-crankshaft timing procedure. of the components must be replaced. 1. Remove all necessary components to access the timing chains. 2. Rotate the engine to No. 1 top dead center. 3. Disassembly: Install No. 6020 Camshaft Positioning Tool (511555) and No. 6009 Cam Positioning Tool (511532) into each camshaft end, as shown, before removing timing chain tensioners and chains to prevent valve train damage. 4. Assembly: Install No. 6020 Camshaft Positioning Tool (511555) and No. 6009 Cam Positioning Tool (511532) into each camshaft end, as shown, before installing timing chains and tensioners to prevent valve train damage.
