Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL® mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin. 2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section. 3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light: Subject: Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination) Models: 2000-2002 Buick Century, Regal 2000-2001 Chevrolet Lumina 2000-2002 Chevrolet Impala, Monte Carlo 2000-2002 Pontiac Grand Prix 2000-2002 Oldsmobile Intrigue • Light is on — Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI. • 4. With the key off, connect the coolant level sensor into the vehicle’s wiring harness. Connect a ground wire (1) to the battery negative terminal. Using a sharp probe (3) attached to the ground wire, ground the coolant sensor probe (2) as shown in the illustration. Make sure a good contact is made. With the key on and the engine off, observe the low coolant light for at least 15 seconds. 5. Using a small wire brush or emery cloth, polish the low coolant level sensor probe to remove any film or oxidation. The probe should be a bright brass color when finished. Use Brake Parts Cleaner to flush removed deposits from the low coolant sensor probe. Reinstall the low coolant sensor into the vehicle and proceed to Step 6. 6. Flush the cooling system and install new DEX-COOL® mixture as outlined in the SI. Check the vehicle’s warranty history to determine if any engine gasket had recently been changed. If there has not been a recent gasket replacement, locate and repair the source of the engine oil contamination

1. Disconnect engine coolant temperature sensor electrical connector and inspect sensor and connector terminals for corrosion and/or evidence of engine coolant. ^If terminals are corroded or if there is evidence of engine coolant proceed to step 4. ^If terminals are not corroded and there is no evidence of engine coolant, reconnect the electrical connector and continue to next step. 2. Perform one or both of the following checks to determine whether the engine coolant temperature sensor is providing the correct temperature indication. If engine coolant temperature sensor reading does not pass either of the above tests, continue with next step. ^If engine is at ambient temperature (vehicle has been sitting overnight or not started for several hours), use a Scan tool to compare the inlet air temperature ( IAT ) to the engine coolant temperature ( ECT ). These two readings should be within 2°C (4°F) of each other. ^If engine is at operating temperature, install a thermometer in the coolant recovery reservoir. With the engine running and A/C off, use a Scan tool to compare the engine coolant temperature sensor reading to the thermometer reading. These two readings should be within 8°C (15°F) of each other If engine coolant temperature sensor reading passes both of the tests above, refer to appropriate symptom diagnostic chart in the Engine/Emissions Controls Section of applicable Engine Service Manual. 3. Turn ignition off. 4Remove coolant surge tank cap. 5. Drain at least 1.9 L (2 Qt.) of engine coolant from the cooling system by opening radiator drain valve or removing engine drain plug. Collect engine coolant in a container. 6. Disconnect engine coolant temperature sensor electrical connector. 7. Remove engine coolant temperature sensor from cylinder head. 8. Obtain replacement engine coolant temperature sensor (P/N 21025106). 9. Use appropriate tap to clean sensor mounting hole of any thread sealant residue. 10. Install engine coolant temperature sensor in cylinder head. Torque: Engine Coolant Temperature Sensor: 8 Nm (71 in-lbs) 11. Inspect harness connector terminals for corrosion and/or evidence of engine coolant. If harness connector terminals are corroded or there is evidence of engine coolant, the harness connector must be replaced with new connector (P/N 12117087-includes: connector, terminals, wires, and splice sleeves). 12. Connect engine coolant temperature sensor connector. 13. Transfer engine coolant drained in step 5 into coolant surge tank. If necessary fill coolant surge tank to the FULL COLD range with 50/50 solution of correct type of antifreeze and clean water. 14. Start engine and check for leaks. 15. Run engine until upper radiator hose is hot, then add additional coolant if needed to bring the level to the FULL COLD level (1991-early 1997) or within the Min./Max. cold range (late l997-2001). 16. Install coolant surge tank cap.

SERVICE PROCEDURE You will be performing the following, as required: • Determine the DTC Stored in ECM from the CONSULT-II Self-diagnosis results. • ECM Part Number Check to determine if this bulletin applies. • ECM Reprogramming (required if the ECM P/N in the vehicle matches one of those listed under “Current ECM P/N” in Chart A -page 2). • Replacing the Rear Oxygen Sensor (required if ECM Reprogramming is needed). Determine the DTC Stored in ECM: 1. Determine which DTC code is stored in the vehicle’s ECM by performing CONSULT-II Self-Diagnosis. 2/4 2. Print out the Self-Diagnosis results for use in ECM Part Number Check , below. See Figure 1 for an example of the CONSULT-II Self-Diagnosis printout. ECM Part Number Check 1. Compare the vehicle’s current ECM P/N (from your CONSULT-II Self Diagnosis printout) to those shown under Current ECM P/N in Chart A , below: Chart A – Current ECM P/N’s: Vehicle Current ECM P/N 1999-2001 Q45 23710-3H000, -3H001, -3H005, -3H006, -3H007 A. If the ECM P/N in the vehicle matches one of those listed under “Current ECM P/N” in Chart A (above): • Perform ECM Reprogramming on page 3. B. If the ECM P/N in the vehicle does not match one of those listed under “Current ECM P/N” in Chart A (above): • This bulletin does not apply. Use the appropriate Electronic Service Manual (ESM) to further diagnose and repair the incident. SELF-DIAG RESULTS SYSTEM ENGINE DATE 01/24/2002 5:35:07 P/N 23710-3H000 DTC Code TP020024 DTC RESULTS TIME HO2S2 (B1) 3 [P0138] Current ECM Part Number 3/4 ECM Reprogramming 1.

1. Remove the cylinder head (see page 6-30 of the 2001-02 Civic Service Manual), and discard it. 2. Inspect the TDC sensor and the timing belt covers for damage (see page 6-57 of the service manual). Replace any damaged parts. 3. Install the new cylinder head (see page 6-50 of the service manual). 4. Check the engine oil level; add oil if necessary.
2 of 2 01-083 5. Do the Idle Learn Procedure: Make sure all electrical items (A/C, audio unit, defogger, lights, etc.) are turned off, then start the engine. Let the engine reach its normal operating temperature (the cooling fan cycle twice). Let the engine idle (throttle fully closed and with all electrical items off) for 10 minutes. 6. If you are working on a 2001 Civic 2-door EX, do the Cruise Control Learn Procedure. Drive the vehicle, and set the cruise control above 40 miles per hour. Continue driving the vehicle for 5 to 10 minutes. NOTE: You can use a smog/chassis dynamometer to do this step instead of driving the vehicle. Do not do this step with the vehicle on a lift.
