DIAGNOSTICS SFI SYSTEM(1ZZ±FE/3ZZ±FE)
AVENSIS REPAIR MANUAL (RM1018E)
BASIC INSPECTION
When the malfunction is not confirmed in the DTC check, troubleshooting \
should be carried out in all the
possible circuits considered as causes of the problem. In many cases, by carrying out the basic engine check
shown in the following flow chart, the location causing the problem can be found quickly and efficiently.
Therefore, using this check is essential in the engine troubleshooting.
1CHECK BATTERY VOLTAGE
NOTICE:
Carry out this check with the engine stopped and ignition switch off. Reference:
OKNG
Voltage11 V or moreLess than 11 V
NGCHARGE OR REPLACE BATTERY

4CHECK AIR FILTER
(a)Visually check that the air filter is not excessively dirty or oily.
HINT:
If necessary, clean the filter with compressed air. First blow from the inside thoroughly, then blow from the
outside of filter. NGREPAIR OR REPLACE

2 PERFORM ACTIVE TEST BY HAND±HELD TESTER(OPERATION OF OCV)
(a) Connect the hand±held tester to the DLC3.
(b) Start the engine and warm it up.
(c) Turn the ignition switch ON and push the hand±held tester main switch ON.
(d) Select the item ºDIAGNOSIS / OBD/MOBD / ACTIVE TEST / VVT CTRL B1º.
(e) Check the engine speed when operating the OCV by the hand±held tester.
Standard:

3 READ OUTPUT DTC(CHECK IF DTC OUTPUT RECURS)
(a) Clear the DTC.
(1) Operating the hand±held tester to erase the codes, or disconnecting the battery terminal or the
EFI and ECTS fuses for more than 60 sec.
(b) Start and warm up the engine.
(c) Drive the vehicle around for 10 minutes or more.
(d) Read output DTC using the hand±held tester.
Standard: No DTC output.
HINT:
*: DTCs P0011/59 or P0012/59 is output when a foreign object in engine oil is caught in some part of the
system. These codes will stay registered even if the system returns to normal after a short time. These for-
eign objects are then captured by the oil filter, thus eliminating the source of the problem.
