This is the inspection procedure to determine whether it is present DTC or memoried one by monitoring the current signal or by using the function of oscilloscope with Hi-scan pro.
Connect scan tool to DLC.
Test condition:ECT 80~90℃(176~203 ℉)
All electrical load : OFF
Ignition switch : ON
Engine is idling.
The data shown above is only for reference and there may be a little difference actually.
It is normal that the output of TPS changes in accordance with that of MAP sensor.
Service standard
Idle : 0%(250~850mV)
Gradually open : Increases
Open fully : 75~85%(4000~4800mV)
Start engine and warm up to operating temperature.
Probe(+) : TPS harness terminal 1
Probe(-) : Chassis ground.
It is normal that the output of TPS changes in accordance with that of MAP sensor.
In case there is no symptom and wrong data but DTC is shown
The problem may be intermittent so slightly shake the connector and harness vertically and horizontally to check if there is any data changes
If the data changes normally, the problem was intermittent so erase DTC and verify the same DTC reoccure.
Go to "Terminal and Connector inspection" procedure.
In case there is symptom and wrong data with DTC
Check open,short or connector’s connection for TPS.
Check the deterioration of TPS performance.
Go to "Circuit Inspection" procedure.
Service standard
Idle : 0%(250~850mV)
Gradually open : Inccreases
Open fully : 75~85%(4000~4800mV)
