Cold DRIVEABILITY Test 4 - Charge Temperature Sensor CIRCUITCHECK

1987 Chrysler Fifth Avenue 5.2 4SECTION Cold DRIVEABILITY Test 4 - Charge Temperature Sensor CIRCUITCHECK
  1. 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
  2. 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.

    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
  3. 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.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
