What Causes No Signal in the Fuel Injector Signal Wire?

[LeElle]

Possible reasons for no signal in the fuel injector signal wire include the computer's inability to determine the working cylinder number or abnormalities in the ignition system. Do not lower the fuel octane rating: For gasoline injectors, the fuel octane rating represents the fuel's anti-knock properties. Generally, the higher the quality of the injector cleaner, the higher the compression ratio, and consequently, the higher the required fuel octane rating. This is also a key focus for catalytic converter cleaning services. Avoid intentionally driving at low RPMs: Deliberately driving at low speeds with high gears increases the engine's load. Excessively low RPMs can also lead to incomplete combustion in the engine, resulting in carbon deposits. This is an important consideration when using fuel injector cleaners.
