the oxygen sensor heater circuit.

Can a bad fuel pump cause a lean code?

A plugged Fuel Filter or poorly functioning Fuel Pump can set the

P0171 code

. The computer hears (accurately) from the Oxygen Sensor that the Fuel Mixture is too lean so the computer keeps increasing the amount of fuel being delivered into the combustion chambers.

What does System Too Lean Bank 1 and 2 mean?

The oxygen sensor alerts your system when the condition is too lean meaning

there's too much oxygen in the exhaust
