How much does it cost to fix a fuel system problem?

Costs vary widely from $100 for a sensor replacement to $800+ for a fuel pump or injector replacement. A proper diagnosis is essential to avoid unnecessary parts replacement.

What causes fuel system codes?

Common causes include faulty fuel pressure regulators, clogged fuel filters, failing fuel pumps, leaking or clogged injectors, and wiring issues in the fuel system control circuits.

P0205

Injector Circuit Malfunction - Cylinder 5

Severefuel system

Overview

The P0205 code indicates a injector circuit malfunction - cylinder 5 condition has been detected by the vehicle's powertrain control module (PCM). This code relates to the fuel delivery and metering system, which is responsible for providing the correct amount of fuel to the engine. When this code is stored, the fuel system is not operating within the expected parameters, which can affect engine performance and fuel economy.

Symptoms

Check Engine Light (MIL) illuminated
Black smoke from exhaust
Difficulty starting the engine
Engine surging at idle

Common Causes

Faulty fuel pressure regulator
Faulty PCM (Powertrain Control Module)
Clogged or dirty fuel filter
Failed fuel pump or weak fuel pressure

Diagnosis Steps

1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
2Check fuel pressure using a fuel pressure gauge; compare to manufacturer specifications
3Inspect fuel lines, connections, and injectors for leaks or damage
4Test the fuel pressure regulator for proper operation
5Check the fuel pump relay and electrical connections
