Since the recent engine refit [ Timing chain + sprockets + tensioner + guide ] ... This car has been a dream to drive ...
Today I've just done a quick check over the car.
A scan shows the following codes:
P0036 HO2S Heater Control Circuit (Bank 1 Sensor 2)
P0136 O2 Sensor Circuit Malfunction (Bank 1 Sensor 2)
P0171 System too lean (Bank 1)
As the engine is a straight-4, I guess that "Bank 1" has no meaning.
All the codes cleared without any issues.
Are these things I should be concerned about ?
Is any action recommended ?
The engine is running perfectly.
