Under normal circumstances, that would be every 25,000 miles or 40,000 kms. So, the most effective way to keep injectors in good working order is to have them removed and inspected at regular intervals. If you plan on running up high mileage on your car then there are a few things you can do to help. Like any other engine part, regular maintenance is the key, to keeping them going. In general, fuel injectors are hard wearing and with a little care, can often last the life of the engine. So, the absence of this sound can indicate, a problem with an injector. Engine Stethoscopeįuel injectors, make a sharp clicking sound, when they are functioning properly. This tool enables a car owner, to listen for any problems with the fuel injectors by placing the tip of the stethoscope on each injector. Listen To The Fuel InjectorsĪnother helpful diagnostic tool, is an engine stethoscope. These are all, fuel & air metering injector circuit related codes.
#Will a bad injector set a dtc code code
For example, a fault with an injector in cylinder one, would give a code of P0201. If you are using a generic (not vehicle manufacturer specific) code reader then you can expect to see codes beginning with P02. If an engine misfires because of a bad injector there will be an error code, that will point to, the injector in question. This will tell you if the Engine Control Unit (ECU) has logged any errors. So, when looking for problems, always start by hooking up an (OBD) code reader. Tracking Down The Problem Hook Up An (OBD) Code Reader Engine Knock or Detonation, which can lead to catastrophic engine failure.Oil thinning, which can lead to, catastrophic engine failure.Surging and bucking, under various throttle loads.Possible Signs Of Fuel Injector Issues, Include: As a result, of normal wear and tear or lack of maintenance. There are many moving parts inside an injector and over time they can fail. The other way an injector will leak is, if the injector body or nozzle cracks. If it breaks, then fuel can leak out, over the engine. The O-ring can become, hard and brittle, from the heat of the engine. So, the most common cause of leaky injectors is the failure of the O-ring, where the injector meets the fuel rail. Over time, these will eventually, block the injector. This causes any fuel left in the injector to evaporate, leaving behind hard deposits, inside the injector.
When you shut off your engine the injector will, soak up the heat of the engine. Over time the nozzle of the injector can become, dirty and partially blocked.
