How to troubleshoot a p0205 injector malfunction?

The following steps will help you troubleshoot a P0205 code: Perform a visual inspection of the injectors and connections. Many problems can easily be found in the harness and connectors. So, begin your diagnosis by visually inspecting the sensor and its connection. First, check for other codes that would indicate cylinder misfire (P0301 – P0308).

What does DTC stand for in fuel injection?

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. In sequential fuel injection the PCM (Powertrain Control Module) controls each injector individually.

What happens if the fuel injector is not working?

Fuel injectors are a vital part of a complex fuel management system. Furthermore, New technology has made fuel injectors more precise than ever in dispensing fuel. If the fuel injectors are not operating properly, then other parts of the engine will be affected as well.

What is the fuel injector circuit code p0201?

For example, a fault with an injector in cylinder one would give a code of P0201. These are all, fuel & air metering injector circuit related codes. Another helpful diagnostic tool is an engine stethoscope. 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.

What causes a p0200 injector to malfunction?

Potential causes of an P0200 code include: 1 Open or shorted injector 2 Injector low internal resistance (basically an injector that works, but is out of specs) 3 Grounded driver circuit 4 Open driver circuit 5 Driver circuit shorted to voltage 6 Wiring harness intermittently shorting against underhood components

What to do if fuel injector circuit malfunctions?

Unplug the PCM connector and ohm the fuel injector driver circuits. Any resistance means there’s a problem. Infinite resistance points to an open in the circuit. Find it and repair it, then retest. If you can find no problem with the harness and there is no fuel injector driver operation, then check the PCM powers and grounds.

What’s the pressure of a diesel injector pump?

Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half of what engines are expected to do today.
