TEMPERATURE AND MANIFOLD ABSOLUTE PRESSURE SENSOR (T-MAP)
OPERATION OVERVIEW
Mounted on the throttle body intake manifold, the T-MAP
sensor performs two functions in one unit.
Air passing through the intake is measured by the T-MAP
and relayed to the ECU. These signals, comprised of
separate air temperature and manifold absolute pressure
readings, are processed by the ECU and compared to its
programming for determining the fuel and ignition
requirements during operation. The T-MAP sensor
provides the ECU with engine load data.
T-MAP SENSOR TEST
The T-MAP sensor is a non-serviceable item. If it is
faulty, it must be replaced.
NOTE
This sensor should only be tested using the Digital
Wrench® Diagnostic Software (dealer only).
T-MAP SENSOR REPLACEMENT
1. Remove the drivers seat and disconnect the
negative (-) battery cable.
2. Remove the cargo box access panel.
3. Disconnect vehicle harness from T-MAP sensor.
4. Remove the retaining bolt and remove the sensor
from the intake boot.
5. Use a light coating of soapy water on the grommet to
