How To Fix Engine Code P0172 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. 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: check engine light is on. fuel consumption is increased. black smoke coming from the exhaust. the strong smell of fuel from the exhaust.
How To Fix Engine Code P0172 P0172 definition: bank 1 has too much fuel or not enough air. issue severity: moderate– extended driving with this code can cause internal engine damage. repair urgency: get this code fixed as soon as possible to avoid damage to spark plugs, pistons, and catalytic converters. diagnosis: it is important to complete the entire diagnostic. How to fix the p0172 code. these are the most common ways to fix a p0172 code: a repair of a vacuum leak. a replacement of a faulty fuel injector, fuel pump, or fuel regulator. replacement of an excessively restricted air filter. replacement of the thermostat or coolant temperature sensor. a replacement of the spark plugs. The most common symptoms of a system too rich code • check engine light • poor idle • excessive fuel smell from the exhaust • black soot inside the tailpipe• low power • engine misfire • stalling • hesitation • hard start, especially a restart after the engine is warm • no start. the most common causes of a p0172 code. The p0172 code is indicative of a system too rich (bank 1) condition in the engine’s air fuel mixture ratio. it signals that the powertrain control module (pcm) has detected a richer than ideal air fuel mixture in bank 1 – the side of the engine with cylinder number one. this imbalance implies that there is too much fuel or too little air.

The method to fix p0172 varies depending on the underlying cause. here are some potential fixes: replace a faulty o2 sensor. clean or replace the maf sensor. clean or replace the fuel injectors. replace the fuel filter or fuel pressure regulator. repair any vacuum leaks in the engine. replace a failed fuel pump. Specifically, the p0172 system too rich code refers to bank 1 of the engine. the pcm monitors the air fuel ratio after combustion has taken place and the air fuel sensor (s) or oxygen sensor (s.
