Connect Scantool to Data Link Connector (DLC).
Monitoring should be performed at cold idle.
Turn "OFF" electrical devices and A/C.
IG KEY "ON"
Monitor "E/GAS TEMP. PRE VGT","E/GAS TEMP. PRE CPF" parameter on the Scantool.
Specification : The difference between "E/GAS TEMP. PRE VGT" and "E/GAS TEMP. PRE CPF" is below 40℃
At IG KEY ON state and as soon as turning engine ON, the difference of output voltage between "E/GAS TEMP. PRE VGT" and "E/GAS TEMP. PRE CPF" must be small to be neglectable.
