Component Inspection

■ Check TPS2 performance

IG KEY "OFF".

Warm up the engine to normal operating temperature.

Compare to "Current Data" and Actual Data about throttle Position Sensor with GDS.

Fig.1) At Acceleration

The TPS1 and TPS2 output values are inversely proportional to each other.

The output value of the TPS1 is proportional to the engine load. (Approx. 0V → 5V)

The output value of the TPS2 is inversely proportional to the engine load. (Approx. 5V → 0V)

■ Confirm Part Inspection

Does the TPS operate properly? (Check variation)

	▶ Go to "Verification of Vehicle Repair" procedure.
	▶ Substitute with a known-good Injector and check for proper operation. If the problem is corrected, replace Injector and then go to "Verification of Vehicle Repair" procedure.
