TEMPERATURE / MANIFOLD ABSOLUTE PRESSURE SENSOR
T-MAP OVERVIEW
Mounted on the intake manifold, the T-MAP sensor
performs two functions in one unit.
The temperature and pressure of the air passing through
the intake is measured by the T-MAP and relayed to the
ECU. These signals 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 should be tested using Digital
Wrench. When connected to Digital Wrench, observe the
Intake Air Temperature reading and the Manifold
Absolute Pressure reading. Intake Air Temperature and
Manifold Absolute Pressure should be close to what the
temperature and pressure are in your environment when
the key is turned on, engine not running. When the
vehicle is started, manifold absolute pressure will be
around 9 PSI (cold engine) and drop to around 6 PSI
(warm engine). If unsure about the readings, compare to
a known good unit.
Wiring harness issues are more likely to be the cause of
a poor running condition than a faulty T-MAP.
The T-MAP sensor is a non-serviceable item. If it is
faulty, it must be replaced.
T-MAP SENSOR REPLACEMENT
1. Remove the 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
q
and remove the sensor
w
from the intake boot.
5. Use a light coating of soapy water on the grommet
e
to aid installation of the new sensor.
6. Install the sensor
w
by inserting it with a twisting
motion to properly seat the grommet
e
.
7. Install the retaining bolt and torque to specification.
