Replacing the fuel filter and air filter will set you back $30 to $50 each plus labor. Since the P0171 DTC can be caused by a variety of faults, it is important to follow the proper diagnostic procedures. If that still doesn’t solve the problem, you want to check for vacuum or exhaust leaks. But if the MAF sensor if faulty or damaged, you need to spend around $40 to $80 for the sensor alone, after labor costs you could be looking at $150. In most cases, cleaning the air filter and MAF sensor is enough to solve the problem. If the sensor is dirty, clean it using a sensor cleaner. If cleaning the MAF doesnt help, it may be a vacuum/air leak somewhere inboard. While you’re at it, you should also check the MAF sensor. The codes are indicating lean conditions on both cylinder banks. The first thing to do is to replace or clean the air filter and fuel filter. Note: This DTC is very similar to P0174 Mazda, and in fact your vehicle may show both codes at the same time. On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder 1.

And unfortunately because of the nature of this code, you’ll spend some time isolating the problem. OBD2 Code P0171 Mazda definition: Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). The cost will depend on the source of the problem. How much does it cost to fix P0171 Fault? Your car or truck has either a P0171, P0174 lean fault code or both stored in the pc, these. (Or maybe used your own OBD scanner to extract the car faults). So your car’s CEL (always check Engine Light) is on and also you had the codes scanned at a local parts shop. There are also times when the fault is caused by a faulty O2 sensor as well. P0171 and P0174 Codes Don’t change an Oxygen Sensor Before Reading This. The bad news is diagnosing a vacuum leak is tricky without using specialized tools like a Smoke Tester. If the motor is not getting enough fuel, the trouble code can also be blamed on a plugged or dirty fuel filter.īut in some cases, it can also mean the existence of a vacuum leak in the MAF sensor or PCV connections. In some cases, the trouble code is also triggered by a sticky or failing fuel injector. The code can also be attributed to a faulty or stuck PCV valve. Clean your dirty MAF! Img creds: FamilyHandyMan Cleaning the MAF with some brake cleaner should help isolate or rule this one out. If the filter is clogged or excessively dirty, this is enough to impede or restrict the air flow, hence resulting in a lean running condition.īesides a dirty air filter, the P0171 code can also be blamed on a dirty or faulty MAF sensor and a clogged fuel filter. The first thing to check is the air filter or air cleaner element. These codes commonly occur on many Ford vehicles, and are set when the powertrain control module (PCM) sees the air/fuel mixture is running too lean (too much air, not enough fuel). A Ford P0171 is a LEAN code for cylinder bank 1, and P0174 is a LEAN code for cylinder bank 2. Dirty or faulty Mass Airflow Sensor (MAF) Ford P0171 & P0174 Lean Codes by Larry Carley copyright 2019.
