2018年12月29日 · We don’t recommend driving with P0172. P0172 is thrown when the oxygen sensors detect that the air-fuel mixture is too rich. A rich fuel mixture contains too much fuel in relation to air. The A/F ratio for ideal combustion is 14.7 parts air to 1 part fuel (14.7:1).

Make: FIAT Code: P0172 Definition: System Too Rich (Bank 1) Description: The intent of this diagnostic is to identify rich or lean fuel system abnormalities which would cause vehicle emissions to exceed 1.5 times any of the standards.

2023年1月7日 · What Does the P0172 Code Mean? The P0172 DTC means that the car’s computer has determined that the fuel system is running too rich. The alert was set off on Bank 1. A rich-running system means that there’s either too much fuel or a lack of oxygen in the air-fuel mixture. Bank 1 indicates it’s located on the side that contains the #1 cylinder.

Car threw an CEL yesterday morning after driving to work. Torque reads it as P0172, but I can't find much information about what this might be in relation to an Abarth. There is no MAF, right? Engine is stock, nothing changed, no fiddling around in the engine bay any time recently. Anyone have some suggestion on where to look?

What does this mean? OBD2 Code P0172 Fiat definition: Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. Note: This DTC is very similar to P0175 Fiat, and in fact your vehicle may show both codes at the ...

2025年3月1日 · The P0172 code indicates a rich fuel mixture on bank 1, causing decreased fuel efficiency, rough idling, and poor engine performance. Common causes include faulty oxygen sensors, clogged fuel injectors, vacuum leaks, and issues with the mass airflow sensor or fuel pressure regulator.

2023年9月28日 · The P0172 code appears when the ECU detects insufficient fuel in the combustion mix. Several symptoms will point that there is a problem with a too-rich mix condition in your engine:

Short term fuel correction is based on upstream O2 Sensor output and is designed for quick engine response. The long term fuel correction compensated for variations in the engine specifications, sensor tolerances and component aging and is designed to correct rich and lean conditions over a longer period of time.

2025年1月10日 · P0172 code gets triggered when the Engine Control Module receives an input signal from the oxygen sensor —also called the air-fuel ratio sensor —indicating that the air/fuel mixture has been running too rich for an extended period of time.
