Control lamps (Renault Espace III)

On vehicles equipped with a high-pressure fuel injection system, there are two injection indicator lamps, one of which lights up during the preheating phase, and the other one - in case of a malfunction of the injection system. When the ignition is switched on, the starting preheating indicator lamp lights up during the preheating phase, then goes out.

When a malfunction of the injection system occurs, the malfunction indicator lamp lights up continuously. The malfunctions that cause the injection system to be switched off include:

• injection system control unit malfunction;
• engine crankshaft speed sensor malfunction;
• main relay or low pressure fuel pump fault;
• injector malfunction;
• mismatch between TDC and camshaft position sensor signals;
• fuel pressure sensor malfunction;
• fuel pressure regulator solenoid valve malfunction;
• accelerator pedal position potentiometer malfunction;
• malfunction of the electronic engine start interlock system;
• lack of required supply voltage to the injection system control unit;
• no voltage on capacitor;
• turbo boost pressure sensor malfunction;
• turbocharger solenoid valve malfunction.

If a fault is detected when the ignition is switched on, the indicator lamp lights up for a few seconds during the preheating phase, goes out, then lights up again if a fault is present.

Note: The on-board diagnostics indicator light with the engine symbol, which comes on when the ignition is switched on, must never come on when the engine is running.
