If both VPA1 and VPA2 are malfunctioning:
Fixed at idle
If either of VPA1 or VPA2 is malfunctioning:
Fuel cut intermittently
After it is returned to normal condition, turn the ignition switch
ON.
5.CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's ECM in the check mode, the 1 trip detection logic is possible instead \
of the 2 trip
detection logic, and the sensitivity to detect faults is increased. This\
makes it easier to detect intermittent
problems.
(a)Clear the DTCs (See step 2).
(b)Set the check mode (See step 3).
(c)Perform a simulation test (See page 01±22).
(d)Check the connector and terminal (See page 01±32).
(e)Wiggle the harness and the connector (See page 01±32).
6. DATA LIST
HINT:
Using the DATA LIST displayed by the hand±held tester, you can read the value of the switches, sensors,
actuators and so on without parts removal. Reading the DATA LIST as a first step of troubleshooting is one
method to shorten diagnostic time.
NOTICE:
The values given below for ºNormal Conditionº are representative valu\
es. A vehicle may still be nor-
mal even if its value differs from those listed here. So, do not solely dep\
end on the ºNormal Condi-
tionº here when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LISTº.
(g) According to the display on tester, read the ºDATA LISTº.
