Cold DRIVEABILITY Test 4 - Charge Temperature Sensor CIRCUITCHECK
- Disconnect both connectors from the computer. Connect an ohmmeter between 10-way connector cavity "9" and 12-way connector cavity "10". Ohmmeter reading should be as follows:CHARGE TEMPERATURE SENSOR CIRCUIT RESISTANCE
Temperature °F (°C) Resistance -40 to 20 (-40 to -7) 382,000-22,000 50-100 (10-38) 36,000-3300 140-245 (60-118) 3900-176 - If resistance checks okay, proceed to COLD DRIVEABILITY TEST 5
. If resistance is not within specifications, disconnect charge temperature sensor connector. Connect an ohmmeter between charge temperature sensor terminals. Resistance should be as shown in CHARGE TEMPERATURE SENSOR RESISTANCE
chart.CHARGE TEMPERATURE SENSOR RESISTANCE
Temperature °F (°C) Resistance -40 to 20 (-40 to -7) 382,000-22,000 50-100 (10-38) 36,000-3300 140-245 (60-118) 3900-176 - If resistance is okay, repair wiring between computer and sensor for a short or open circuit. If resistance is not within specifications, replace charge temperature sensor.
