ENGINE – 2JZ–GE ENGINE TROUBLESHOOTING

2  Check throttle position sensor.

1 (E2)
2 (IDL1)

P  (1) Disconnect throttle position sensor connector.
   (2) Disconnect the vacuum hose from the throttle
       body. than apply vacuum to the throttle opener
       (See page EG–219).

C  Measure resistance between terminals 2 (IDL1)
   and 1 (E2) of throttle position sensor connector.

OK
Throttle Valve          Resistance
Fully closed            Less than 0.5 kΩ
Opened                  1 MΩ or higher

OK

NG  Adjust or replace throttle position sensor.
    (See page EG–223)

Check and repair harmless or connector between en-
gine control module and throttle position sensor.

3  Check voltage between terminal A/C of engine control module connector and
   body ground.

SST
ECM

       (See page EG–404)
       SST 09990–01000
   (2) Start the engine.

C  Measure voltage between terminal A/C of engine
   control module and body ground.

OK
A/C Switch              Voltage
OFF                     7.5 – 14 V
ON                      0 – 1.5 V

OK

NG  Check A/C compressor circuit.
    (See page AC–62)

Check and replace engine control module.
