Power Window & Engine Sensor Troubleshooting

The document provides troubleshooting procedures for issues with power window regulators and motors, as well as air flow sensors and engine coolant temperature gauges, for various vehicle models. It includes check points for sensor output values and procedures for inspecting parts like regulators, motors, sensors and wiring when vehicles exhibit problems like windows not working properly, engines stalling or misfiring, or incorrect coolant temperature readings. Replacing only damaged parts, rather than whole assemblies, is recommended when possible to avoid warranty issues.

Quality Problem & Trouble Shooting


Subject Models Condition
Due to the air flower sensor malfunction, the engine makes any trouble.

International A/S & Parts Team 2001.08.10

Check procedure the HFM sensor Gasoline engine

Correction
In case of air flower sensor damage, inform what phenomenon to happen and how to check it.

Engine phenomenon
1. In quick start, the engine stops and start impossible again.
2. In quick start, fast accelerating is not available, and the gear shifting malfunctions. 3. The connector of HFM sensor disconnects, the engine stop. 4. Knocking noise sounds on Bosch type of ECU(only CM600s model) 5. The engine stops as soon as start. 6. In idling, after raising up the rpm, the engine hunting happens. 7. In all cases of the above phenomenon excluding 6 item, the diagnosis result is normal with scan 100.

Check point
1. Diagnosis specification for sensor output Model 400 500 In idling 11.5 12.2 13.5 14.2 At 4,200 rpm 250 400 250 400 600(Bosch) 12Kg/h 600(VDO) 14.4 15.5

2. In Bosch type, the knocking noise happen when the air volume comes out 8Kg/h in idle. So, At first disconnect the sensor, clean the internal area with air, then finally the test result is the same as before, replace it with new one. 3. In condition of full accelerating, if the output value is below 200, the acceration damage happen. 4. When to diagnose, follow the above 4,200rpm, because of valiable engine load.

Main Cause
Fixed at 90 degree - The wiring from temp. gauge to temp. sensor is shorted to body. - The temp. sensor is shorted. Fixed at 0 degree - The wiring from temp. gauge to temp. sensor is opened. - The temp. sensor is opened.

Work procedure
- Check the wiring from temp. gauge to temp. sensor. - Check the temp. sensor
