Component Inspection





Component Inspection

1. After engine starting, connect Scantool and monitor the "TPS 1" & "TPS 2" parameters on the Scantool data list.
A. Specification: Refer to "Signal Waveform & Data" in the "General Information" procedure
1. TPS 1 : Output voltage increases smoothly in proportion with the throttle valve opening angle after starting.
- Engine "ON" & Closed throttle status : Approx. 0.2 - 0.8V, Engine "ON" & Wide open throttle : Approx 4.2 - 4.8V
2. TPS 2 : Output voltage decreases smoothly in inverse proportion with the throttle valve opening angle after starting.
- Engine "ON" & Closed throttle status : Approx. 4.2 - 4.8V, Engine "ON" & Wide open throttle : Approx 0.2 - 0.8V




2. Is sensor data near the specified value ?
YES
1) Go to next step as below
NO
1) Check TPS for contamination, deterioration, or damage. Substitute with a known-good TPS and check for proper operation. If the problem is corrected, replace TPS and then go to "Verification of Vehicle Repair" procedure.

CAUTION: It is necessary to perform the TPS adaptation procedure with Scan tool when the throttle body assembly or ECM is replaced.
TPS adaptation procedure
1. Erase previous TPS adaptation value using Scan tool.
2. 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)
3. After TPS adaptation, the system normality should be confirmed by reading out "FMY" on the Scan Tool
