Camshaft Position Sensor (CMPS) (PUMP)
The camshaft position sensor (PUMP) is located on the electronic
fuel injection pump.
The sensor consists of a permanent magnet, core and coil.
When engine is running, gap between sensor and drive shaft rotat-
ing plate will periodically change. Permeability near the sensor also
changes.
Due to the permeability change, the magnetic ¯ux near the core is
changed. Therefore, the voltage signal generated in the coil is
changed.
The ECM receives the voltage signal (6 pulses/2 engine revolu-
tions).
These signals are used for tachometer indication.
CONSULT REFERENCE VALUE IN DATA MONITOR MODE
Remarks: Speci®cation data are reference values.
MONITOR ITEM CONDITION SPECIFICATION
CKPSzRPM (REF)+Tachometer: Connect
+Run engine and compare tachometer indication with the CONSULT
value.Almost the same speed as the
CONSULT value.

ECM TERMINALS AND REFERENCE VALUE
Remarks: Speci®cation data are reference values and are measured between each terminal andV43(ECCS

PROCEDURE
1) Turn ignition switch ``ON'' and select ``DATA MONITOR''
mode with CONSULT.
2) Start engine and run it for at least 2 seconds at idle
speed.
(If engine does not run, turn ignition switch to ``START''
for at least 2 seconds.)

1) Start engine and run it for at least 2 seconds at idle
speed.
(If engine does not run, turn ignition switch to ``START''
for at least 2 seconds.)
2) Turn ignition switch ``OFF'', wait at least 5 seconds and
then ``ON''.
3) Perform ``Diagnostic Test Mode II (Self-diagnostic
results)'' with ECM.
