CAMSHAFT POSITION (CMP) SENSOR
Camshaft position sensor is used for timing pulsing of fuel injectors. Camshaft sensor signal is also used by Coil On Plug (COP) engines to determine firing of ignition coils. See CAMSHAFT POSITION SENSOR or CMP SYNCHRONIZER under FUEL SYSTEM.
CRANKSHAFT POSITION (CKP) SENSOR
Note. Engine front cover design precisely locates CKP sensor. No CKP sensor adjustment is necessary.
CMP SYNCHRONIZER
| CAUTION | Synchro Positioner (T96T-12200-A) is required to properly install synchronizer. Failure to use synchro positioner during installation will cause fuel injection to be out of time and may cause engine damage. |
FUEL SYSTEM PRESSURE RELEASE
| WARNING | ALWAYS relieve fuel pressure before disconnecting any component under fuel pressure. DO NOT allow fuel to contact engine or electrical components. |
- Remove fuel tank cap. Using Fuel Pressure Gauge (T80L-9974-B), release pressure from system at pressure relief valve (Schrader valve) located on fuel injection manifold rail.
- If fuel pressure gauge is not available, disconnect Inertia Fuel Shutoff (IFS) switch. See INERTIA FUEL SHUTOFF (IFS) SWITCH LOCATION table. Remove fuel filler cap to release fuel tank pressure. Crank engine for 15 seconds to release system pressure.

Spring Lock Coupling
- Release fuel pressure. See «FUEL SYSTEM PRESSURE RELEASE»(ref-131450-S32295932042001121700000). Place indicated spring lock coupler over coupling. See «SPRING LOCK COUPLER IDENTIFICATION»(ref-131450-S38764156572001121700000) table. To release female fitting from garter spring, push coupler along tube into coupling. (Scheme 15)
- Pull spring lock coupling apart. Remove coupler from disconnected spring lock coupling. Check for damaged garter spring and "O" rings. Wipe end of lines with clean cloth.
- To install, place NEW "O" rings onto tube. Lubricate ends of lines with clean refrigerant oil. Locate White indicator ring (if equipped), which may have slipped down length of tube. Insert White indicator ring into cage of male fitting.
- Push fitting together with a slight twisting motion. White indicator ring will pop free of cage to indicate that male fitting is properly seated over flared end of female fitting.
