2. Measure the resistance between the coolant temperature
sensor terminal No.1 and No.4 with the coolant temperature
sensor disconnected.
Inspection
1. Measure the coolant sensor input voltage between the ECU
terminal No.79 and No.78 while the ignition switch in "ON"
position.
Notice
Replace wiring and coolant temperature sensor if out of
specified value.

Vacuum 500 mbar
Lines and connections leaking.
Faulty PLA vacuum unit.
Test step 1
Connect vacuum pump (14) with Y adapter to PLA
vacuum unit (5). Run engine at idle speed.
YES
NO
(Remove the connection hose from vacuum pump)
Connect vacuum pump (14) direct to PLA vacuum unit
(5) and pressurize with vacuum.
Vacuum is built up and idle speed increases approx.
150-200 rpm
YESNO
Faulty PLA vacuum unit
(Coolant Temperature 30°C)
Stop the engine Seal the air admission line with plug.
Connect the vacuum pump to line to thermovalve and
pressurize the line with vacuum.
Vacuum is built up.
