T-MAP SENSOR
Operation Overview
Mounted on the end of the intake, the T-MAP
performs
two functions in one unit. The T-MAP detects intake air
temperature as well as manifold absolute pressure.
These sensor signals, comprised of separate intake 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 engine operation. The T-MAP
provides the ECU with engine load data.
TMAP Test / Replacement
The T-MAP is a non-serviceable item and can only be
tested using Digital Wrench®. If the sensor is faulty, it
must be replaced.
NOTE: This sensor should only be tested using
Digital Wrench® Diagnostic Software (dealer only).
To replace the TMAP sensor:
1. Remove the engine access cover in the cargo box.
2. Remove the TMAP mounting bolt.
3. Install new TMAP sensor and torque the mounting
bolt to specification.
TMAP Mounting Bolt:
