Resistance Inspection

NOTE: Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. (See HOW TO USE THIS MANUAL .)

Disconnect MAP/boost air temperature sensor.

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 SYSTEM REMOVAL/INSTALLATION [L3 WITH TC] .)
If the MAP/boost air temperature sensor is normal, but PID are out of specification, perform the "CIRCUIT OPEN/SHORT INSPECTION ".
