po106 is a map sensor code

DTC P0325

  • Knock Sensor (KS) Circuit
  • DTC P0463 (Sedan)

    DTC Descriptor

    DTC P0463

  • Fuel Level Sensor Circuit High Voltage
  • DTC P1682

    DTC Descriptor

    DTC P1682

  • Ignition 1 Switch Circuit 2

  • Engine may operate in a reduced engine power mode.Circuit/System Verification
  • If DTCs P0685, P0689, P0690, or B1380 are set, diagnose those DTCs first.
  • Ignition ON, engine OFF, observe the Ignition 1 voltage signal, and the EC Ignition Relay Feedback signal parameters, on the scan tool. Both parameter values should display no more than 3 volts difference, between the two parameters.
  • Ignition OFF, observe the ignition 1 voltage signal parameter, on the scan tool. The parameter value should be 0 volts , before the ECM powers down.
  • Circuit/System Testing

  • Ignition ON, observe the Ignition 1 Signal and EC Ignition Relay Feedback scan tool parameters to determine which is less than B+.
  • Ignition OFF, remove the relay that corresponds to the scan tool parameter that is less than B+.
  • Important: 6 ohms or greater in the circuit/underhood fuse block will cause the DTC to set.

  • Ignition On, connect a 3A fused jumper wire between B+ and the applicable ignition 1 circuit terminal. Verify that the applicable scan tool parameter displays B+.
    • If the applicable scan tool parameter is less than the specified value, test the ignition 1 circuit for an open/high resistance. If the circuit tests normal, replace the ECM.
  • If all circuits test normal, test or replace the applicable relay.
