What does code P042E mean?

What does OBD-II fault code P042E mean? OBD-II Code Decreased engine performance is defined as a Exhaust Gas Recirculation “A” Control Stuck Open. EGR (Exhaust Gas Recirculation) systems are used to reduce the combustion temperature, thus reducing emissions.

How do I know if my DPFE sensor is bad?

A faulty DPFE sensor can cause several problems:

  1. increased emissions.
  2. rough idle.
  3. hesitation.
  4. decreased engine power.
  5. decreased fuel efficiency.
  6. failed emissions.
  7. check engine light on.

What does P0405 code mean?

Exhaust Gas Recirculation Sensor A

What does OBD-II fault code P0405 mean? OBD-II Code P0405 is defined as a Exhaust Gas Recirculation Sensor A Circuit Low. NOx gases, which are a leading cause of acid rain and in some people, respiratory problems, are formed when the engine combustion temperatures become too high (2500° F).

Can you drive with a bad DPFE sensor?

You shouldn’t drive with a faulty DPFE sensor. If you are noticing a rough idle or a lack of engine power, it’s best to replace the DPFE sensor and EGR valve. Leaving the car with a faulty EGR system only causes trouble passing emissions tests and leads to further air pollution.

What happens if the fuel rail pressure sensor goes bad?

The fuel pressure sensor is one of these sensors, and if it fails then it can significantly decrease your car’s ability to supply its engine with the right amount of fuel. This can lead to symptoms like weak acceleration, difficulty starting the car, stalling, and poor fuel economy.
