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 INFORMATION .)

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 MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION .)
If the MAP/boost air temperature sensor is normal, but PID are out of specification, perform the "Circuit Open/Short Inspection".
