Inspection Procedure

2004 Toyota Matrix XR, FWD, StandardSECTION Inspection Procedure
WARNING: This page is about a different car, the 2003 Toyota Sequoia. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check voltage between terminals TEC and SG of integration control and panel. 

    PREPARATION:

    Remove integration control and panel with connectors still connected.

    CHECK:

    1. Turn ignition switch to ON.
    2. Measure voltage between terminals TEC and SG of integration control and panel connector at each temperature.

    OK:

    1. Voltage: 
    2. at 0°C (32°F) : 2.0 - 2.4 V 
    3. at 15°C (59°F) : 1.4 - 1.8 V 
    NOTE: As the temperature increases, the voltage decreases.
    1. NG : Go to step 2. 
    2. OK : Proceed to next circuit inspection shown in  PROBLEM SYMPTOMS TABLE  . However, if DTC 17 is displayed, check and replace integration control and panel. 
  2. Check rear evaporator temperature sensor. 

    PREPARATION:

    Remove rear evaporator temperature sensor (See DISASSEMBLY ).

    CHECK:

    Measure resistance between terminals 1 and 2 of evaporator temperature sensor connector at each temperature.

    OK:

    1. Resistance: 
    2. at 0°C (32°F) : 4.5 - 5.2 kΩ 
    3. at 15°C (59°F) : 2.0 - 2.7 kΩ 
    NOTE: As the temperature increases, the resistance decreases.
    1. NG : Replace rear evaporator temperature sensor. 
    2. OK : Go To Next Step. 
  3. Check harness and connector between rear evaporator temperature sensor and integration control and panel (See  HOW TO USE THE DIAGNOSTIC CHART AND INSPECTION PROCEDURE  ). 
    1. NG : Repair or replace harness or connector. 
    2. OK : Check and replace integration control and panel.

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.
