DTC Confirmation Test (Overall Function Check)

WARNING: This page is about a different car, the 2002 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the following test to check overall function of coolant overtemperature enrichment protection. During this test, DTC may not be confirmed.

With CONSULT-II

  1. Allow engine to cool. Check coolant level in radiator and reservoir tank. If coolant level is okay, go to next step. If coolant level is low, go to DIAGNOSTIC PROCEDURE  .
  2. Check coolant mixture ratio. If coolant mixture ratio is 45-55 percent, go to next step. If coolant mixture ratio is not 45-55 percent, change coolant, then go to step  4 .
  3. If coolant was filled by customer, go to DIAGNOSTIC PROCEDURE  . If coolant was not filled by customer, go to next step.
  4. Start engine and let it idle. Turn A/C switch to OFF position. Ensure A/C system is not operating. If A/C is operating, repair A/C circuit. See appropriate article in AIR CONDITIONING & HEATING. If A/C system is not operating, go to next step.
  5. With engine idling, perform ENG COOLANT TEMP in ACTIVE TEST mode with CONSULT-II. Set ENG COOLANT TEMP to 203°F (95°C). If cooling fans operate at low speed, go to next step. If cooling fans do not operate at low speed, go to DIAGNOSTIC PROCEDURE  .
  6. Set ENG COOLANT TEMP to 212°F (100°C). If cooling fans operate at high speed, go to next step. If cooling fans do not operate at high speed, go to DIAGNOSTIC PROCEDURE  . After repair, go to next step.
  7. Check for blocked coolant or radiator air passage. If problem is found, repair as necessary. If problem is not found, go to next step.
  8. Check ECT sensor as shown in illustration. See Figure . If ECT sensor is okay, go to next step. If ECT sensor is not okay, replace ECT sensor, then go to next step.
  9. Check ignition timing. See ON-VEHICLE ADJUSTMENTS article. Ignition timing should be 4-15 degrees BTDC at idle. If ignition timing is okay, system is okay at this time. If ignition timing is not okay, perform BASIC INSPECTION. See ON-VEHICLE ADJUSTMENTS article.

With Generic Scan Tool

  1. Allow engine to cool. Check coolant level in radiator and reservoir tank. If coolant level is okay, go to next step. If coolant level is low, go to DIAGNOSTIC PROCEDURE  .
  2. Check coolant mixture ratio. If coolant mixture ratio is 45-55 percent, go to next step. If coolant mixture ratio is not 45-55 percent, change coolant, then go to step  4 .
  3. If coolant was filled by customer, go to DIAGNOSTIC PROCEDURE  . If coolant was not filled by customer, go to next step.
  4. Start engine and let it idle. Turn A/C switch to OFF position. Ensure A/C system is not operating. If A/C is operating, repair A/C circuit. See appropriate article in AIR CONDITIONING & HEATING. If A/C system is not operating, go to next step.
  5. Turn ignition off. Disconnect ECT sensor harness connector. See Figure . Connect a 150 ohm resistor between ECT sensor harness connector terminals. Start engine. If cooling fans operate, go to next step. If cooling fans do not operate, go to DIAGNOSTIC PROCEDURE  .
  6. Check for blocked coolant or radiator air passage. If problem is found, repair as necessary. If problem is not found, go to next step.
  7. Check ECT sensor as shown in illustration. See Figure . If ECT sensor is okay, go to next step. If ECT sensor is not okay, replace ECT sensor, then go to next step.
  8. Check ignition timing. See ON-VEHICLE ADJUSTMENTS article. Ignition timing should be 4-15 degrees BTDC at idle. If ignition timing is okay, system is okay at this time. If ignition timing is not okay, perform BASIC INSPECTION. See ON-VEHICLE ADJUSTMENTS article.
