Crank Angle Sensor

For testing information, see TESTS W/CODES article.

DETONATION (KNOCK) SENSOR RESISTANCE ⁽¹⁾

Application

Ohms

All Models

532,000-588,000

⁽¹⁾	Measure resistance between ground and connector terminal.

OXYGEN SENSOR VOLTAGE ⁽¹⁾

Application

Volts

All Models

0.1-0.9

⁽¹⁾	With engine running at normal operating temperature, quickly snap throttle open and closed. Measure voltage between oxygen sensor connector terminal and ground. Voltage should vary within specification.

THROTTLE POSITION SENSOR (TPS) RESISTANCE (TOTAL RESISTANCE)

Application ⁽¹⁾

⁽²⁾ TPS Connector Terminals

Total: Ohms

Legacy

Black & Red

Loyale

1.8L PFI

Black & White

6000-18,000

1.8L TBI

Black & Red

3500-6500

XT & XT6

Black & White

6000-18,000

⁽¹⁾	Justy 1.2L carbureted & PFI engines are not equipped with TPS.

⁽²⁾	Disconnect TPS connector. At component side of connector, connect ohmmeter between these terminals.

THROTTLE POSITION SENSOR (TPS) RESISTANCE (VARIABLE RESISTANCE)

Application ⁽¹⁾

⁽²⁾ TPS Connector Terminals

Variable: Ohms

Legacy

5800-17,800

Throttle Open

Black & Green

1500-5100

⁽¹⁾	Justy 1.2L carbureted & PFI engines are not equipped with TPS.

⁽²⁾	Disconnect TPS connector. At component side of connector, connect ohmmeter between these terminals.

THROTTLE SWITCH (IDLE SWITCH) CONTINUITY

Application ⁽¹⁾

⁽²⁾ Terminals

Justy 1.2L PFI

⁽³⁾ Blue/White & Black/Red

Legacy

Brown & Black

Loyale

1.8L PFI

Blue/White & Black/Red

1.8L TBI

Light Green & Black

Blue/White & Black

XT6

Green/Yellow & Black

⁽¹⁾	Justy 1.2L carbureted models are not equipped with throttle switch.

⁽²⁾	On all models except Loyale PFI, disconnect TPS connector. On Loyale PFI, disconnect throttle switch connector. On all models, check continuity between indicated terminals of connector. There should be continuity with throttle closed and no continuity with throttle open.

⁽³⁾

In addition to idle switch function, throttle switch also contains wide open throttle switch function. To test wide open throttle switch function, check continuity between Green/Red and Black/Red wire terminals of throttle switch connector. There should be continuity with throttle fully open (at least 50 degrees) and no continuity with throttle closed.
