If resistance and all tests applicable to the CPS are
good, try a new ECM. Refer to
ECM REPLACE-
MENT
.
If resistance value is incorrect, repair the connec-
tors or replace the wiring harness between ECM
connector and the CPS.
CPS Replacement
Refer to MAGNETO/STARTER.
MANIFOLD ABSOLUTE
PRESSURE AND TEMPERATURE
SENSOR (MAPTS)
vmr2008-136-002_c
NOTE: This sensor is a multifunction device.
Sensor Pressure Function
When engine is started and it runs at idle speed,
the sensor reads the absolute pressure and stores
it in the ECM. Thereafter, it reads the manifold air
pressure at operating RPMs.
Ensure sensor is correctly installed on intake
manifold. Otherwise, the MAPTS could gener-
ate a fault code for an unexpected sensor range
at idle when it reads the absolute pressure.
Remove sensor and check for oil or dirt on its
end and if problem persists, check throttle plate
condition/position and the wiring harness. Per-
form the following tests.
MAPTS Test with B.U.D.S.
Use B.U.D.S. software. Refer to
COMMUNICA-
TION TOOLS/B.U.D.S. SOFTWARE.
Select the Monitoring tab.
Start engine.
Needle should move as you throttle the engine.
Otherwise, perform the voltage and continuity
tests.

MAPTS Input Voltage Test
Check the voltage output from ECM to the pres-
sure sensor.
Remove LH side panel. Refer to
BODY.
Turn ignition key ON and set engine stop switch
to RUN.
Disconnect the MAPTS connector.
