P2096

POST CAT FUEL TRIM SYS B1
(Post catalyst fuel trim system 
too lean bank 1)

The output voltage computed by ECM from the 
A/F sensor 1 signal is shifts to the lean side for a 
specified period.

• A/F sensor 1
• A/F sensor 1 heater
• Heated oxygen sensor 2
• Fuel pressure
• Fuel injector
• Intake air leaks
• Exhaust gas leaks
