Summit Wagon AWD L4-1795cc 1.8L SOHC (1994)
Camshaft Position Sensor: Oscilloscope Patterns and Waveforms
WAVE PATTERN INSPECTION USING AN ANALYZER MEASUREMENT METHOD
1. Disconnect the camshaft position sensor & crankshaft position sensor connector and connect the special tool (test harness: MB991348) in between.
(All terminals should be connected.)
2. Connect the analyzer special patterns pickup to camshaft position sensor & crankshaft position sensor connector terminal A. (When checking the
camshaft position sensor signal wave pattern)
3. Connect the analyzer special patterns pickup to camshaft position sensor & crankshaft position sensor connector terminal 3%. (When inspecting
the crankshaft position sensor signal wave pattern.)
ALTERNATE METHOD (TEST HARNESS NOT AVAILABLE)
1. Connect the analyzer special patterns pickup to ECM terminal 68. (When inspecting the camshaft position sensor signal wave pattern.)
2. Connect the analyzer special patterns pickup to ECM terminal 69. (When inspecting the crankshaft position sensor signal wave pattern.)
STANDARD WAVE PATTERN
Wave pattern observation points: Check to be sure that cycle time T becomes shorter when the engine speed increases.
