P0208 Injector Circuit Malfunction Cylinder 8

OBD2 Code: P0208

Description: Injector Circuit Malfunction – Cylinder 8

Definition: This code indicates that the Engine Control Module (ECM) has detected a malfunction in the injector circuit for cylinder number 8. The issue could be due to an electrical problem such as a short or open circuit, or a mechanical failure within the injector itself.

P0002 Fuel Volume Regulator Control Circuit Range/Performance

OBD2 Code: P0002

Description: Fuel Volume Regulator Control Circuit Range/Performance

Definition: This code is set when there is an issue with the fuel volume regulator control circuit not operating within its expected range. It may indicate a problem with the fuel pressure sensor, wiring, or the fuel pump itself.

p0208 – Injector Circuit Malfunction Cylinder 8

Common Misdiagnosis

OBD2 Code: P0208

Description: Injector Circuit Malfunction Cylinder 8

Common Misdiagnosis: Replacing the fuel injector without checking for wiring issues or ECM problems.

OBD2 Code: P0202

Description: Injector Circuit Malfunction Cylinder 2

Common Misdiagnosis: Assuming the injector is faulty when the issue may be due to a poor electrical connection or a problem with the powertrain control module (PCM).

 

Common Diagnostic Steps

OBD2 Code: P0208

Description: Injector Circuit Malfunction Cylinder 8

• Check the injector circuit for any open or shorted wires.
• Inspect the fuel injector connector for corrosion or damage.
• Test the fuel injector resistance to ensure it is within specifications.
• Use a noid light to check for proper signal from the engine control module (ECM) to the injector.
• Examine the ECM for any faults or issues that may affect injector operation.
• If necessary, replace the faulty fuel injector with a new one.

OBD2 Code: P0202

Description: Injector Circuit Malfunction Cylinder 2

• Inspect wiring and connectors related to cylinder 2’s fuel injector for signs of damage or corrosion.
• Measure the resistance of cylinder 2’s fuel injector and compare it against manufacturer specifications.
• Utilize a noid light to verify that there is an appropriate pulse signal from the ECM to cylinder 2’s injector.
• Check for continuity in the wiring harness between the ECM and cylinder 2’s fuel injector connector.
• If all tests fail, consider replacing cylinder 2’s faulty fuel injector with a new unit.
