What does trouble code p0175 mean on Honda Pilot?
A common trouble code with the Honda Pilot is P0175. This code number references a number that is given to you when you plug a vehicle into an OBDII scanner. It’s not the most complicated OBDII trouble code to diagnose. It is also one of the most common. It means that the motor is running with a rich condition.
What causes air flow code p0172 and p0175?
The fuel mixture grows rich and eventually, the code sets. An “over reporting” Mass Air Flow Sensor can be a common cause of a code P0172 and P0175. Essentially, this means that the Air Flow Sensor is telling the computer that much more air is entering the engine than actually is.
What does it mean when fuel trim is p0172?
Ideally, the Long Term Fuel Trim should be close to 1 to 2 percent. When a code P0172 is set, it means that the Fuel Trim is anywhere from -15 percent to as low as -30 percent compensated. When this happens, the computer knows that there is an improper condition in the control of the Fuel System.
What causes a vacuum leak on a Honda Pilot?
Vacuum Leaks – With the Honda Pilot, one of the most common cause for the P0175 code to be thrown is a vacuum leak. Take a look around and see if you can find the vacuum leak. Here’s a great YouTube video on how to find a vacuum leak.

What does the DTC code p0172 stand for?
Diagnostic trouble code (DTC) P0172 stands for “Fuel System Too Rich (Bank 1)”. Your car’s computer will set the code when it determines that there’s too much fuel (or too little oxygen) in the engine’s air-fuel mixture.
Can a dirty air filter cause a p0172 code?
Like any other OBD-II code, a P0172 can be caused by a variety of problems. In other words, there is no easy way to pinpoint what’s causing the problem other than examining the critical parts responsible for maintaining the right fuel mixture. A dirty air filter can cause code P0172.
What does rich mean on a Honda Pilot?
A rich condition indicates that the air fuel mixture has too much fuel or not enough air. This would be the opposite of a lean condition, which’ll throw P0174. The P0175 code on a Honda Pilot will often be thrown if the fuel injection system is not operating properly.
What to do if check engine light code p0172 persists?
If check engine light code P0172 persists after you have inspected the air intake system and cleaned the Mass Air Flow (MAF) Sensor, perform a fuel pressure test. If any components in the fuel system are failing, replace them as necessary.
What causes the O2 sensor to read p0172?
It is important to complete the entire diagnostic process when diagnosing P0172. Many people will replace the air-fuel sensor or O2 sensor as soon as they get a bad reading, but the root cause is often a dirty or faulty Mass Air Flow (MAF) Sensor or vacuum leak, thus causing the O2 or A/F sensor to read differently to compensate.
Is the p0172 fuel injection system too rich?
P0172 with P0175 or MAF DTCs – If you note both P0172 and P0175 or concurrent MAF-related DTCs, then you can likely rule out individual cylinder, ignition, and fuel injector problems. Instead, focus on the fuel injection system and the MAF.
What does the p0172 Honda engine code mean?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The cost to diagnose the P0172 HONDA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
