Kia Carens. Manual — part 71

2001 > 1.8L DOHC >

Inspection

Thottle posirion sensor

1. Disconnect connector from throttle position sensor.

2. Connect ohmmeter between sensor terminals A and B.

3. Verify that resistance increases linearly according to throttle angle.

Specification:2kΩ±0.4kΩ(with throttle valve closed)

4. If resistance is not as specified, replace the throttle

5. Connect throtle position sensor connector.

Voltage

1. Verify that throttle is at the closed throttle position.

2. Turn ignition switch ON.

3. Connect voltmeter between terminal A(BLK wire) and C(RED/GRN wire) on throttle posirion sensor

connector.

4. Verify that throttle valve is at closed throttle position.

5. Fully open throttle valve and verify that viltage at terminal C is within spectification.

6. If not as specified, replace throttle position sensor.

Specification:

Measuring condition

Voltage(V)

Fully closed

0.4~0.6V

Fully open

4.1~4.3V

Removal

The throttle position sensor is not adkustable or replaceable. The thrittle position wensor is part of the
throttle body assembly.
For throttle body removal, refer to Fuel System, Section 22.

Installation

For throttle body installation, refer to Fuel System, Section 22.

Fuel System

Engine Control System - Heated Oxygen Sensor
(HO2S)

Fuel System

2001 > 1.8L DOHC >

Inspection

1. Warm up the engine to normal operation temperature.

2. Run engine at idle speed.

3. Connect a voltween terminal D (YEL/GRN wire) and groung.

4. Increase and decrease engine speed quickly several times.

5. Verify that meter reding varies between 0~1.0V.

Rear oxygen sensor voltage does not fluctuate as quickly as front oxygen sensor.

6. If not as speecified, inspect:

A. On-board diagnostic system
B. System inspection

C. Intake manifold vavuum
D. Fuel line pressure

7. If all systems are normal, replace the heated oxygen sensor.

Front & rear heated oxygen sensor heaters

1. Ensure ignition switch is OFF.

2. Disconnect heated ocygen sensor connector.

3. Connect ohmmeter between terminal A and B and measure resistance.

Specification:3.6~20.5Ω(68°F{20°C})

4. If not as specified, replace heated oxygen sensor.

Tightening torque:22-36 lb-ft(30~49 N·m,3~5 kg-m)

5. Reconnect heated oxygen sensor connector.

Removal

1. Disconnect heated oxygen sensor connector.

2. With standard oxygen sensor socket, remove heated oxygen sensor and washer.

Installation

1. Install heated oxygen sensor and washer.

Tightening lb-ft (30~49 N·m, 3~5 kg-m)

2. Reconnect heated oxygen sensor connector.
