DTC P0110 INTAKE AIR TEMPERATURE SENSOR; Diagnostic Procedure; Steps 1-3

EF & EC-7084prose procedure

Step 3 source says 'sensor harness connector terminal 14' which mismatches the sensor's 1-5 pin layout shown in SEF656Z — likely refers to terminal in the IAT side (possibly terminal 3 of the MAFS-IAT connector for IAT-specific ground). Captured verbatim from page.

    Turn ignition switch "OFF".
  2. 2
    Disconnect mass air flow sensor harness connector. (See NEF150A)
  3. 3
    Turn ignition switch "ON".
  4. 4
    Check voltage between terminal 1 and ground with CONSULT-II or tester. (See SEF656Z)
  5. 5

  6. 6
    OK or NG: - OK → GO TO 3. - NG → GO TO 2.

Step 2 — DETECT MALFUNCTIONING PART

  1. 1
    Check the following: - Harness for open or short between ECM and intake air temperature sensor
  2. 2
    → Repair harness or connectors.

Step 3 — CHECK GROUND CIRCUIT

  1. 1
    Turn ignition switch "OFF".
  2. 2
    Disconnect ECM harness connector.
  3. 3
    Check harness continuity between intake air temperature sensor harness connector terminal 14 and ECM terminal 14. Refer to wiring diagram. Continuity should exist.
