This test must be performed with engine cold.

1. With diagnostic read-out tool connected to engine harness connector, tee a vacuum gauge into vacuum line at MAP sensor, then start engine.
2. Place system into Engine Running Test Mode 68.
3. If vacuum on display is within two inches of that of gauge, proceed to Test 15 step F. DR-15F Charge Temperature Sensor
4. If vacuum on display is not within one inch of that of gauge, proceed to Test 15 step E. DR-15E Sensor Calibration MAP Sensor
