Check TPS resistance
IG "OFF".
Disconnect TPS connector.
Measure the resistance between terminal 2 and 3 of TPS component side.
Specification :
ITEM | Specification |
TPS Resistance (㏀) | 2㏀ ± 20% (20℃) |
Is the measured resistance within specification ?
YES
Go to "Check ECM" as follows
NO
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.
Check ECM
Key "OFF".
Connect the scantool and select "Simulation SCAN" in the menu.
Connect channel A of scantool with terminal 1 of TPS harness connector, and key "ON" & ENG "OFF".
Simulate voltage at signal line.
Does the signal output of TPS change according to simulation voltage?
YES
Thoroughly check connectors for looseness, poor connection, bending, corrosion,contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.
NO
Substitute with a known - good ECM and check for proper operation.
If the problem is corrected, replace ECM and go to "Verification of Vehicle Repair" procedure.
