A faulty fuel sensor can provide inaccurate readings of the fuel level in a vehicle's tank, leading to incorrect fuel gauge readings on the dashboard. This may cause drivers to underestimate or overestimate the amount of fuel available, potentially resulting in running out of fuel unexpectedly or unnecessary refueling. Additionally, it may trigger warning lights or error messages, complicating vehicle diagnostics. Overall, it affects the vehicle's efficiency and reliability.
When a Subaru has a faulty O2 sensor the fuel management is out of whack.
yes
Faulty fuel pump. Incorrect fuel pump pressure. Dirty fuel filter. Faulty engine coolant temp sensor.
p0171 fuel system lean bank 1 Causes include faulty oxygen sensor, weak fuel pump, plugged fuel filter, low fuel pressure, misfire, faulty map sensor, etc.
There are a few reasons. crankshaft position sensor, faulty fuel pump, fuel pump regulator, throttle position sensor, oxygen sensor. Need to have it diagnosed.
Fuel rail pressure sensor fault. Most usually an out of range fault caused by a plugged fuel filter, bad fuel pump or faulty sensor. (In that order)
A fuel rail pressure regulator could cause trouble.
The P1135 is set when the Engine Control Module detects a heated oxygen sensor heater circuit malfunction. This could be caused by a faulty air-fuel ratio sensor or a faulty engine control module.
A faulty crank sensor would cause no spark and no fuel.

Your relay sensor is likely faulty
It is a faulty sticking injector, or LAMBDA Sensor, Or faulty ECU
