Component Inspection
TPS Inspection
1. Start engine and install scan tool.
2. Monitor the "TPS VOLTAGE1" and "TPS VOLTAGE2" parameters on the Scantool data list.
Specification : Refer to "Signal Waveform & Data" in the "General Information" procedure
- Output of TPS1 increases smoothly in proportion with the throttle valve opening angle.
- Output of TPS2 decreases smoothly in inverse proportion with the throttle valve opening angle.
3. Are the TPS VOLTAGE 1&2 within the specification?
ETC Motor Inspection
1. Visually/physically inspect the restriction or any foreign objects in throttle body.
2. Clean or replace as necessary and go to "Verification of Vehicle Repair" procedure.
If OK, go to next step as below.
3. Ignition "OFF".
4. Disconnect the ETC motor harness connector.
5. Measure resistance between 'ETC output 1' terminal and 'ETC output 2' terminal of ETC motor harness connector. (Component side)
Specification : 1.2-1.8 Ohms at 20 °C (68 °F)
6. Is resistance within specification?
NOTE:
It is necessary to perform the TPS adaptation procedure after the ETC assembly or PCM replacing.
TPS adaptation procedure
Ignition "OFF" and then "ON" without cranking. Wait for 10 seconds under enable conditions.
-> Enable conditions : Battery >10V & Intake Air Temp. >5.3 °C (41.5 °F) & 5.3 °C (41.5 °F) < Engine Coolant Temp. <99.8 °C (211.6 °F)
