What causes a Honda Civic to throw a p0172 code?

This would be the opposite of a lean condition, which’ll throw P0171. The P0172 code on a Honda Civic will often be thrown if the fuel injection system is not operating properly. Typically the code will be triggered by a rich condition in the engine. There aren’t usually any drivability issues associated with P0172.

What is the Honda fuel injection code p0171?

P0171 HONDA Tech Notes. If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persists the front oxygen (O2) sensor may need to be replaced.

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.

What does the OBDII trouble code p0171 mean?

The OBDII trouble code P0171 – System Too Lean (Bank 1)means that the engine air-fuel mixture is too lean, or there is too much air and too little fuel. Driving a car with the code P0171 can cause more damage to the engine over time, as when the engine runs lean, the combustion temperature is higher.

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.

How much does it cost to repair a Honda p0171?

Please try again later. The cost of diagnosing the P0171 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. Most auto repair shops charge between $75 and $150 per hour.

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 are the p2195 and p1172 error codes?

Error codes: P2195, P1172, P1174 and P219 Mile: The vehicle was driving for over 6 months Symptom: there was a missing fuse for the A/F ratio sensor heaters. After the fuse was replaced, the PCM sets P2195, P1172, P1174 and P2197.

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.
