ON BOARD DIAGNOSTIC SYSTEM — Troubleshooting Code No. 10 (Intake Air Temperature Sensor — In Volume Air Flow Sensor)
F2-82flowchartCODE No. 10 (INTAKE AIR TEMPERATURE SENSOR — IN VOLUME AIR FLOW SENSOR)
1
STEP 1: Does intake air temperature sensor circuit have a poor connection?
Yes
Repair or replace connector
No
2
STEP 2: Is code No. 08 also present?
Yes
Check for an open circuit in wiring from volume air flow sensor terminal C or D to ground
No
3
STEP 3: Does wire harness between intake air temperature sensor and ECM have continuity? (See continuity table)
No
Repair or replace
Yes
4
STEP 4: Is resistance of volume air flow sensor between terminals C and G OK? (See resistance table)
No
Replace volume air flow sensor
Yes
5
STEP 5: Is same code No. present following "After-repair procedure"? (Refer to page F2-92)
No
Intake air temperature sensor and circuit OK
Yes
6
Replace ECM
STEP 3 — Intake air temperature sensor (in volume air flow sensor) to ECM continuity
D
ECM3D
E
ECM2K
STEP 4 — Volume air flow sensor resistance (terminals C and G)
20°C (68°F)
Resistance (ohm)2,000-3,000
60°C (68°F)
Resistance (ohm)400-700
