Left Bank Intake Manifold Temperature
Sensor Fault, Param #7407.1
Left bank sensor reading is outside normal range of 4
– 20mA
Right Bank Intake Manifold Temperature
Sensor Fault, Param #7407.2

Catalytic Converter Temperature
Difference Too Low, Param #7267
The temperature difference between the inlet and
outlet of the ctalytic converter is too small, indicating
that the catalyst is not working properly to reduce
emissions
Catalytic Converter Temperature
Difference Too High, Param #7268
The temperature difference between the inlet and
outlet of the catalytic converter is too large, indicating
something is wrong with the catalytic converter such
as it might be plugged.
