How do I fix error code P0172?

What repairs can fix the P0172 code?

  1. A repair of a vacuum leak.
  2. A replacement of a faulty fuel injector, fuel pump, or fuel regulator.
  3. Replacement of an excessively restricted air filter.
  4. Replacement of the thermostat or coolant temperature sensor.
  5. A replacement of the spark plugs.

What causes system too rich?

There are several reasons why this problem could exist. The most common reasons include a faulty oxygen sensor or a dirty mass air flow sensor (MAF). In addition, here are some additional causes of throwing code PO172. Cooling system that’s been retrofitted (ie: thermostat removed, fan running direct, etc.)

Can I drive with a P0172 code?

It is okay to drive a vehicle with P0172 for a short period of time, but driving with this code for an extended period of time can cause internal engine damage and failure of the catalytic converter.

What does Bank 1 too rich mean?

System too rich bank 1 means that the oxygen sensor in bank 1 identified a rich situation (presence of inadequate amount of oxygen in the exhaust). The detection of too much fuel mean that there is insufficient oxygen. Bank 1 is technically cylinder 1, which is the area of the vehicle’s engine with the first cylinder.

What is Bank 1 and Bank 2 on a car?

Bank 1 and bank 2 simply refer to either side of the engine. Most commonly, bank 1 houses the front most cylinder on the engine cylinder 1, and bank 2 is the opposite side of the engine.

Can a dirty air filter cause a lean code?

The Mass Air Flow sensor is behind the air filter, so if the filter were choked off, the MAF sensor would be reading less air, and the computer would use less fuel to compensate. This is called “unmetered air” and is the biggest cause of a lean running engine on a modern fuel injected car.

Is it OK to drive with P0171 code?

It is okay to drive a vehicle with P0171 for a short period of time, but driving with this code for an extended period of time can overheat the engine and cause internal engine damage.

How much does it cost to fix P0171 code?

What is the cost to resolve a P0171 code? This code will require a diagnostic check, which will run about $100 depending on the time it takes to find the issue. As there is a laundry list of reasons why the engine runs lean, the average price per repair will vary greatly.

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. Your bank 1 or bank 2 sensors will be referred to as “sensor 1” or “sensor 2”. Sensor 1 refers to “upstream” sensors, or the ones near the engine and before the catalytic converter.

Can you drive a car that is running lean?

just dont boost hard and you should be fine. a lean running car will be prone to detonation/pinging which can destroy it quickly.

How do you tell if you’re running rich or lean?

When a car is running rich, it means the engine is receiving too much fuel and too little air. Your car will still crank and drive if it’s running rich, but you’ll likely experience symptoms like low gas mileage, slow acceleration and strong smell of gasoline (especially when idling).
