MANIFOLD ABSOLUTE
PRESSURE AND TEMPERATURE
SENSOR (MAPTS)
vmr2006-012-004_d
1. Manifold absolute pressure and temperature sensor (MAPTS)
NOTE: This sensor is a multifunction device.
MAPTS Access
Remove the RH side panel. Refer to
section.
MAPTS Pressure Function
Before the engine is started, when power is ap-
plied to the system, the sensor measures the
ambient air atmospheric pressure. The ambient
pressure is, at that moment, stored in the ECM.
Thereafter, once the engine is started, it mea-
sures the air pressure in the intake manifold at
operating RPMs.
The sensor must be correctly installed on intake
manifold. Otherwise, the MAPTS could generate
a fault code for an unexpected sensor range at idle
when it reads the atmospheric pressure. If this
is the case, remove sensor and check for oil or
dirt on its end and if problem persists, check throt-
tle plate condition/position and the wiring harness.
Perform the following tests.
MAPTS Pressure Function Quick Test
1. Connect vehicle to the latest applicable
B.U.D.S. software version.
2. In B.U.D.S., click the following:

2. MAPTS pressure reading
3. Look for and take note of the MAPTS pressure
reading while the engine is stopped.
4. Perform the same test with a new MAPTS and
compare both readings.
Values have to be within ± 3.4 kPa (.5 PSI).

MAPTS Input Voltage Test
Check the voltage output from ECM to the pres-
sure sensor.
1. Turn ignition key ON.
2. Set emergency engine stop switch to RUN.
3. Remove electrical connector from MAPTS.
4. Using a multimeter, measure input voltage as
per following table.
