3. MAP sensor ground circuit (PB) open-circuit inspection
-1. Turn the ignition switch OFF.
-2. Check for continuity between the No. 1 (White/Red)
terminal of the MAP sensor wire harness side 3P
connector and No. 6 (White/Red) terminal of the
ECM connector A.
◆
Is there continuity?
YES - Go to the step 4.
NO -
Repair open circuit between the MAP sensor
and ECM.
4. MAP sensor ground circuit (SG) open-circuit inspection
-1. Turn the ignition switch OFF.
-2. Check for continuity between the No. 2 (Green) ter-
minal of the MAP sensor wire harness side 3P con-
nector and the body ground.
◆
Is there continuity?
YES - Go to the step 5.
NO -
Repair open circuit between the MAP sensor
and ECM.
5. MAP sensor inspection
-1. Connect the ECM connector A and the MAP sensor
3P connector.
-2. Turn the ignition switch ON and check the PB volt-
age with the HDS (Dr. H or Pocket Tester).
◆
Is there 2.76 ~ 2.96 V*?
YES - Recheck with a new ECM.
NO -
Replace the MAP sensor.
*: Indicates the voltage under the condition of 969 -
1,042 hPa.
