The ECM uses the fuel rail pressure sensor to continuously monitor fuel pressure. If the ECM detects a problem, such as an unexpected increase or decrease in fuel pressure, or excessive or insufficient fuel pressure, that is, higher or lower than commanded, it will set diagnostic trouble code (DTC), DTC P0089 – “Fuel Pressure Regulator Dirty injector: You can clean the injectors of your Renault Trafic, do not think twice to consult our content page on this subject to get the process. If it doesn’t work, you will have to change them. Leaky injector: The change and the purchase of a joint kit will only cost you a few tens of euros, but you still need to be able to change it The injection pump takes care of pressurizing the fuel and transferring it to the injectors, and the injectors will relieve the fuel in the form of micro-drops into the cylinders of your Dacia Duster. The benefit of fuel injection is to have a much more precise dosage than a carburettor and to allow a better air/fuel mixture and therefore a In the "16-valve" 1.6 liters, the ignition coils occasionally "fly out", and in the 2.0-liter units the fuel injection system can "act up" - until the engine warms up, it is unstable, and there is also a metallic ringing caused by weakening exhaust manifold crosspieces. The problem is solved by a simple welding of the collector. P2146 is a diagnostic trouble code (DTC) for "Fuel Injector Group “A” Supply Voltage Circuit/Open". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light Sorted by: 5. If the bubbles are in the fuel line that leads to the high pressure pump, then air in the system would reduce the pumps ability to pressurise the fuel correctly. Diesel injectors require high pressure fuel in order to achieve proper atomisation; liquids don't burn, so the fuel needs to enter the cylinder in very fine droplets in 10649 posts · Joined 2012. #9 · Feb 19, 2023. I think its a software glitch in your code reader. Yes injectors need coding and it often a idea to reset or relearn injector pilot injection cut off etc. When you code the injector it often resets anyway and then relearns but it needs warm engine. Potential causes of an P0200 code include: Open or shorted injector. Injector low internal resistance (basically an injector that works, but is out of specs) Grounded driver circuit. Open driver circuit. Driver circuit shorted to voltage. Wiring harness intermittently shorting against underhood components. Year: 2003. Variant: 1.1 petrol. Problem Categories. Running Rough, Starting & Power Loss. hi people i cant get my 2003 peugeot 206 to start just bought new battery car turns over fine but car will just not start. checked fuses and the fuse for the fuel pump (15amp) was blowen so replaced it but still car wont start. i have lifted rear seat up P0253 Code. P0253 is widely known as the diagnostic trouble code for “Injection Pump Fuel Metering Control A Low (Cam/Rotor/Injector.”. This trouble code can be caused due to multiple reasons. Hence, in order to diagnose the specific cause for this code, there may be a need for you to hire professional help. dfeb1i.
