P0471 Engine Code Repair
Meaning of P0471 engine trouble code is a kind of powertrain trouble code and when your car's 'P0471 Check Engine' light comes on, it's usually accompanied by a sinking feeling in the pit of your stomach. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off.

- Car not starting
If one of these reasons for P0471 code is occuring now you should check P0471 repair processes.
Now don't ask yourself; What should you do with P0471 code ?
The solution is here :
P0471 Possible Solution:
Power Steering Pressure (PSP) Switch Signal Malfunction The PCM counts the number of times vehicle speed transitions from 0 to a calibratable speed. After a calibratable number of speed transitions the PCM expects that the PSP input should have changed. This DTC is set if the transition is not detected. Vehicle towed with engine running Power steering hydraulic concern was repaired but DTC was not erased PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged Check, if possible, if vehicle was towed or power steering service was performed. Observe PSP V PID while checking wires for intermittents.

The oxygen (02) sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions.
P0471 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0471 OBD-II Trouble Code The Exhaust Back Pressure (EBP) sensor is a variable capacitance sensor that, when supplied with a 5-volt reference signal from the Engine Control Module ( P0471 code.Main reason For P0471 CodeThe reason of P0471 OBD-II Engine Trouble Code is Throttle/Pedal Position Sensor/Switch A Circuit Intermittent. |
P0471 DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
