Injector & Injector Pump Coding

Modern vehicles rely on precise electronic communication between injectors and the engine ECU. Unprogrammed injectors can lead to poor fuel economy, rough performance, and starting issues.

Injector coding is essential when replacing injectors on many new vehicles. Previously, this could only be performed by main dealerships, often resulting in high repair costs. Mobile Car Diagnostics now provides a cost-effective, high-quality injector recoding service, saving you time and money.

How Injector Coding Works

• Common rail injectors have unique calibration codes.
• These codes are programmed into the engine ECU to ensure proper performance.
• Delphi injectors may have the calibration code on a parts sticker; others may be on the injector solenoid.
• Electronic programming ensures your ECU recognises all new components for smooth engine operation.

Important Recommendations

Always code injectors before fitting them to the engine. The ECU will accept the calibration code prior to installation, confirming correct injector supply. If the ECU does not accept the code, it may indicate an operator error or incorrect injector. Incorrect injectors can be returned before installation.
