Tester Display
Short FT B1S1
Long FT B1S1

Data List	Result	Proceed to
Short FT B1S1 + Long FT B1S1	-20% or higher, or less than 20%	A
Short FT B1S1 + Long FT B1S1	Other than above	B

HINT:

"Total FT Bank 1" is used to detect an abnormal air fuel ratio. As the value of "Total FT Bank 1" is corrected by the ECM before it is displayed in the Data List, the displayed value may not be equal to the sum of the measured "Short FT B1S1" and "Long FT B1S1".
An abnormally lean or rich tendency can be checked by reading the following Data List items: A/F Learn Value Idle Bank 1, A/F Learn Value Low Bank 1, A/F Learn Value Mid No.1 Bank 1, A/F Learn Value Mid No.2 Bank 1, A/F Learn Value High Bank 1, A/F Learn Value Idle (Port) Bank 1, A/F Learn Value Low (Port) Bank 1, A/F Learn Value Mid No.1 (Port) Bank 1, A/F Learn Value Mid No.2 (Port) Bank 1 and A/F Learn Value High (Port) Bank 1.
The following may cause a lean air fuel ratio (an operating range in which the air fuel ratio learned value correction is +20% or more):
1. Decrease in fuel injector assembly injection volume
2. Decrease in mass air flow meter sub-assembly output (due to existence of foreign matter)
3. Air leaks in intake system after mass air flow meter sub-assembly
4. Decrease in fuel pressure (at fuel filter, fuel pump, fuel main valve assembly or fuel suction plate sub-assembly)
On vehicles which the learning value for each operating range can be checked, if the value of "A/F Learn Value High (Port) Bank 1" or "A/F Learn Value High Bank 1" only is corrected to the positive side, a malfunction in the fuel system (clogging of the fuel pump or fuel filter) is suspected.
On vehicles which the learning value for each operating range can be checked, if the value of "A/F Learn Value Idle (Port) Bank 1", "A/F Learn Value Low (Port) Bank 1", "A/F Learn Value Idle Bank 1" or "A/F Learn Value Low Bank 1" only is corrected to the positive side, an air leak after the mass air flow meter sub-assembly is suspected.
The following may cause a rich air fuel ratio (an operating range in which the air fuel ratio learned value correction is -20% or less):
1. Increase in the fuel injector assembly injection volume
2. Purge VSV system
