INSPECT THROTTLE POSITION SENSOR

Using an ohmmeter, measure the resistance between each terminal.

THROTTLE POSITION SENSOR TERMINALS RESISTANCE

Clearance between lever and stop screw	Between terminals	Resistance
0 mm (0 in.)	VTA - E2	0.2 - 5.7 kΩ
Throttle valve fully open	VTA - E2	2.0 - 10.2 kΩ
-	VC - E2	2.5 - 5.9 kΩ
