Step Action Value(s) Yes No 1 Was the “On-Board Diagnostic (OBD) System Check” — Go to Step 2 Go to OBD System Check 2 1. Ignition “ON,” engine “OFF.” Data List. Is the value displayed greater than the value shown? 85 kPa Go to Step 3 Go to Step 13 3 1. Remove the MAP sensor from the intake manifold but leave the electrical harness connected. 2. Connect a hand operated vacuum pump to the MAP sensor. 3. Observe the MAP display while slowly applying vacuum up to 20” Hg as indicated on the pump Each 1” of vacuum applied should result in a 3 to 4 kPa Did the MAP value change smoothly through the entire — Go to Step 13 Go to Step 4 4 With 20” Hg vacuum applied to the MAP sensor, is the 34 kPa Go to Step 5 Go to Step 13 5 Disconnect the vacuum source from the MAP sensor. Does the MAP sensor reading return to its original — Go to Step 6 Go to Step 13 |
