From page EC-495

P2099


Trouble diagnosis name:
POST CAT FUEL TRIM SYS B2
(Post catalyst fuel trim system
too rich bank 2)

DTC detecting condition:
The output voltage computed by ECM from the
A/F sensor 2 signal is shifts to the rich side for
a specified period.


Possible Cause:
• A/F sensor 1 (bank 2)
• A/F sensor 1 heater
• Heated oxygen sensor 2 (bank 2)
• Fuel pressure
• Fuel injector
• Intake air leaks
• Exhaust gas leaks

 

sounds like possible leaking injector bank 2
