The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors based on the angle of the air vane in the air flow meterwhich in turn is determined by the volume of air passing the vane, and by the control pressure.

When injectors are out, carefully unbolt all jetroinc from injection unit, so that no washers will be lost, and reattach them in a way that lines would go over right wing and injectors would be outside engine compartment – of course, first put some rag over the wing.

Although Mercedes requires that it be removed and discarded, and after the adjustments be replaced by a new one, with care it can be re-used. Useful for testing oxygen sensor and also can be used to test MAF potentiometer better than multimeter can. If you have an oscilloscope to measure this timing, fine.

Upper path is the one that provides variable resistance, lower path is solely for contact. A jetronlc of Except if the price is really expensive, you should buy the right one as it’s already set up.

Voltage gan also be measured directly by prying off connector boot. Your name or email address: I can find the pressure test, but nothing on the system as such.

If the mixture is rich it will read above 0. This lambda signal is not a replica of the voltage from the oxygen sensor. As per L-Jetronic, a vane-type airflow sensor is used. See other items More
