DTC Troubleshooting: P0108 (3)
DTC P0108:
 MAP Sensor Circuit High Voltage
NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.
  1. Turn the ignition switch to ON (II).
  1. Check the MAP SENSOR in the DATA LIST with the HDS.
Is about 160 kPa (1,197 mmHg, 47.1 in.Hg), or 4.49 V or more indicated?
YES -
Go to Step 3 .
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the MAP sensor and the ECM/PCM.■
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the MAP sensor 3P connector.
  1. Connect MAP sensor 3P connector terminals No. 2 and No. 3 with a jumper wire.
  1. Turn the ignition switch to ON (II).
  1. Check the MAP SENSOR in the DATA LIST with the HDS.
Is about 160 kPa (1,197 mmHg, 47.1 in.Hg), or 4.49 V or more indicated?
YES -
Go to Step 8 .
NO -
Go to Step 20 .
  1. Turn the ignition switch to LOCK (0).
  1. Remove the jumper wire from the MAP sensor 3P connector.
  1. Turn the ignition switch to ON (II).
  1. Measure the voltage between MAP sensor 3P connector terminals No. 1 and No. 3.
Is there about 5 V?
YES -
Go to Step 16 .
NO -
Go to Step 12 .
  1. Turn the ignition switch to LOCK (0).
  1. Jump the SCS line with the HDS.
  1. Disconnect ECM/PCM connector C (49P).
  1. Check for continuity between ECM/PCM connector terminal C14 and MAP sensor 3P connector terminal No. 3.
Is there continuity?
YES -
Go to Step 27 .
NO -
Repair open in the wire between the ECM/PCM (C14) and the MAP sensor, then go to Step 22 .
  1. Turn the ignition switch to LOCK (0).
  1. Jump the SCS line with the HDS.
  1. Disconnect ECM/PCM connector C (49P).
  1. Check for continuity between ECM/PCM connector terminal C11 and MAP sensor 3P connector terminal No. 2.
Is there continuity?
YES -
Go to Step 27 .
NO -
Repair open in the wire between the ECM/PCM (C11) and the MAP sensor, then go to Step 22 .
  1. Turn the ignition switch to LOCK (0).
  1. Reconnect all connectors.
  1. Turn the ignition switch to ON (II).
  1. Reset the ECM/PCM with the HDS.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0108 indicated?
YES -
Check for poor connections or loose terminals at the MAP sensor and the ECM/PCM, then go to Step 1 .
NO -
Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.■
  1. Reconnect all connectors.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0108 indicated?
YES -
Check for poor connections or loose terminals at the MAP sensor and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM, then recheck. If the ECM/PCM was substituted, go to Step 1 .
NO -
If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.■
