Disconnect CTS connector and remove CTS.
Install the new CTS and torque to 18 N•m
(159 lbf•in).
Reinstall remaining removed parts.
MANIFOLD ABSOLUTE
PRESSURE SENSOR (MAPS)
smr2009-030-036_c
TYPICAL
1. Manifold absolute pressure sensor (MAPS)
NOTE: This sensor is a dual function device.
When engine is started and it runs at idle speed,
the sensor takes the atmospheric pressure and
stores it in the ECM. Thereafter, it takes the man-
ifold absolute pressure at operating RPMs.
Ensure sensor is correctly installed on intake man-
ifold. Otherwise, the MAPS could generate a fault
code for an unexpected sensor range at idle when
it reads the atmospheric pressure. Remove sen-
sor and check for oil or dirt on its end and if prob-
lem persists, check throttle plate condition/posi-
tion and the wiring harness. Perform the follow-
ing tests.
MAPS Voltage Test
To gain access to the MAPS, remove the required
parts as described in
CTS REPLACEMENT.
Disconnect connector from MAPS.
