INSPECT THROTTLE BODY ASSEMBLY

Check the resistance.
1. Using an ohmmeter, measure the resistance between the terminals.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Specified Condition
1 (M-) - 2 (M+)	0.3 to 100 Ω at 20°C (68°F)
3 (E2) - 5 (VC)	2.0 to 4.0 kΩ at 20°C (68°F)

If the result is not as specified, replace the throttle body.
