What does P0202 Cylinder 2 Injector Circuit Open mean on vauxhall vectra b?

P0202 relates to the fuel injector on cylinder No2. The code SUGGESTS that the injector has no electrical power to it. These work on a constant 12V feed and the ground is supplied by the ECU by a predetermined map. i.e. open circuit = no complete electrical circuit. The most effective way of checking this is with an oscilloscope. A multi meter may not capture the power at the correct time due to the slow refresh rate.


What does diagnostic code p0205 mean?

Diagnostic code P0205 refers to a malfunction in the fuel injector circuit for cylinder number five in an internal combustion engine. This code indicates that the Engine Control Module (ECM) has detected an issue, such as an open or short circuit, affecting the fuel injector's operation. Common causes can include a faulty injector, wiring problems, or issues with the ECM itself. Addressing this code typically involves inspecting the injector and its connections, as well as testing the wiring.


What does an open injector circuit code mean?

An open injector circuit code typically indicates a problem in the fuel injector circuit, where the engine control unit (ECU) detects that the electrical connection to the injector is interrupted or not functioning properly. This could be due to a broken wire, a faulty connector, or a malfunctioning injector itself. As a result, the affected injector may not receive the necessary signal to open and allow fuel to flow, potentially causing engine performance issues. Diagnosing the specific cause often requires checking the wiring and components associated with the injector circuit.

What does it mean on a 1999 Pontiac sunfire when the injector circuit is open?

The injector circuit is the injector itself and each of the two wires connected to it all the way to their other ends. Open means no connection at all. If you have a code with "open circuit" in it's description, consider that "open circuit or high resistance" is usually a better description. Before you go any further, make sure the electrical connector at the injector hasn't come unplugged.
