Attention: the procedure for checking the throttle position sensor is given in chapter "fuel injection system (MFI) ".
1. Checking the automatic transmission fluid temperature sensor.
- A) Remove the automatic transmission fluid temperature sensor.
- b) Measure resistance between leads "1" And "2" sensor connector.
Automatic transmission fluid temperature | Resistance |
0°C | 16.7-20.5 kOhm |
100°C | 0.57-0.69 kOhm |
- V) Install the automatic transmission fluid temperature sensor and tighten the bolt.
- Tightening torque: 10-12 Nm
2. Check the vehicle speed sensor.
- A) Remove the vehicle speed sensor and connect a 3-10 kΩ resistance to it as shown in the figure.
- b) Rotating the shaft of the vehicle speed sensor, make sure 8 that the terminals "2" - "3" voltage is applied to the sensor connector (4 pulses per revolution).
- V) Install the vehicle speed sensor.
3. Checking the automatic transmission control relay.
- A) Remove the automatic transmission control relay.
- b) Check for continuity between terminals "1" And "3" control relay when no power is applied.
- V) With connector wires "crocodile" connect the output "2" automatic transmission control relay with a positive battery terminal, and the output "4" - with negative terminal.
- G) Check for continuity between terminals "1" And "3" control relay when the relay is energized (with wires connected to the battery terminals).
- d) If the relay does not work as described, replace the automatic transmission control relay.
4. Checking the engine start inhibit switch.
- A) Disconnect the start inhibit switch connector.
- b) Check the condition of the circuit between the terminals of the connector at various positions of the switch according to the table below.
Table. Checking the switch.
1. Checking the resistance of the automatic transmission solenoid valves.
- A) Remove the solenoid valve housing cover.
- b) Disconnect the solenoid valve connectors.
Solenoid valves.
1 - downshift clutch control solenoid valve, 2 - second gear brake control solenoid valve, 3 - torque converter lock-up clutch control solenoid valve, 4 - first gear and reverse gear brake control solenoid valve, 5 - overdrive clutch control solenoid valve.
- V) Measure resistance between leads "1" And "2" each solenoid valve.
- Rated value: 2.7-3.4 ohm (at 20°С)
- G) If the resistance is out of specification, replace the solenoid valve.
- d) Install the cover of the solenoid valve body, having previously applied sealant to the mating surface, and tighten the bolts.
- Tightening torque of the cover bolts: 8-10 Nm
- Sealant: Hyundai genuine sealant TV1281B or similar
