Manifold Pressure/Vacuum Sensor: Testing and Inspection
Boost Air Temperature Sensor Inspection
BOOST AIR TEMPERATURE SENSOR INSPECTION [L3 WITH TC]
Resistance Inspection
NOTE:
-
Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. See: Description and
Operation
1. Disconnect MAP/boost air temperature sensor.
2. Measure the resistance between the MAP/boost air temperature sensor terminals A and B using a tester.
-
If not as specified, replace the MAP/boost air temperature sensor. See: Intake Air Temperature Sensor/Service and Repair
-
If the MAP/boost air temperature sensor is normal, but PID are out of specification, perform the "Circuit Open/Short Inspection".
Specification
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See See: Engine Control Module/Service and Repair/Removal and Replacement.)
2. Inspect the following wiring harnesses for an open or short circuit. (Continuity check)
Open circuit
-
If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
-
MAP/boost air temperature sensor terminal A and PCM terminal 2AV
-
MAP/boost air temperature sensor terminal B and PCM terminal 2N
-
MAP/boost air temperature sensor terminal C and PCM terminal 2AU
