Without this you might either use too much fuel or run your engine too lean. Some cars Volvo 6-cylinder have a higher fuel pressure of 2. There are two independent injector circuits they fire in pairs and if you look in the switch a single contact slides up between a sort of interlocking zipper sort pattern of contacts, so as the contact slides up it first hits one side, then the other. Pin 2 is no longer used and is not even part of the plug. You can just do the basic test of verifying their power supply, their sensors and vibration of all injectors. These values are good enough for most service and troubleshooting work.
There is a tab that keeps the terminal in place when you push it on a male connector. You can also measure the nose on your trigger point's cams. I found missing voltage on fuel pump but could not see any loose wire there. Verify the operation of each injection valve by disconnecting the electrical supply to each injection valve, one at a Fuel Injection Valves time and determine if the engine speed drops when the valve is disconnected. K-Jet fuel pumps do not fit without pressure limiting valve! The book contains theory of operation, development, and practical troubleshooting information. The sales sheet gives you a basic idea of what the unit does but it's not very descriptive.
It can be pin 12, pin 13 or even just ground. Pressure is set and regulated by the Fuel Pressure Regulator. Therefore it should always be mounted on rubber feet and in 90° to drinving direction. Check the air-flow sensor function by removing the connection on the back of the sensor. Also there is a deadzone or Hysterisis between the connection of the two directions.
Check for engine hesitations caused by loose contacts by moving the wiring harnesses and watching for changes in Connectors and Wiring the rpms. This is only input signal. Some mechanics consider it a good trick, to reomove air temperature sensor when idle-run is not perfect. Bus Boys sells a tool to remove the terminals from the connectors. Only happens at steady rpm under load.
Only then can I be sure that no one has misadjusted it, that aneroid cells and springs are still okay and that full-load transition starts at right vacuum pressure. The Bosch connectors only come in black so you'll loose your color coding unless you repaint the connectors to match. No shipping fee, No waiting nervously for the postal delivery, you can start doing your repairs right away! I recently came across a Bosch L-Jetronic tester. It's not that we're about to take the information and make competition for them, but sometimes we need to know details for service and troubleshooting purposes! It is more important not to see a 0 and that all groups show similiar values. When you have enough fuel in glasses, put them on a board and compare levels in each glass. Braking and accelerating enforces too much stress on diaphragms and aneroid cells.
Anders has modeled these in pSpice and presents this on his site: ----------------------- Sheet 2. Sometimes you can loose that voltage quicker than you might think. These manuals are your number one source for repair and service information and specifically written for the do-it-yourself as well as the experienced mechanics worldwide used to use this factory manual to fix your vehicle. I have repaired several ones on water cooled engines by replacing expansion element and holder. However, some variations in the system exist, including by model year.
That is why you first have to verify all component no. I'll try to get an even better picture: Comb contact, showing evidence of wiping contact, but practically no wear. It should be only a few Ohms. The width of these pulses is independent of engine speed and load, and from Kerfoot's schematic, they are about 1. And for the rest you have Bosch Classic Center or this forum.
The original wiring was labelled with numbers so you'll be able to rewire without too much confusion unless they've rubbed off or your harness is so dirty you can't read it. It is fully sufficient and you save hundreds of Euros. Do not do this, you now know better. The voltage regulator and the injection resistors are collocated with this component. When new, they have 2,5 to 2,6 mm.
Der Schließwinkel der Auslösekontakte unten im Verteiler ebenfalls. If not, test trigger contacts first. . Originally, Volkswagen adapted the L-Jetronic for the Type 4 air cooled 411 engines sold in the United States due to more stringent emissions and fuel consumption regulations. I do know cheaper soruces as you can read in.
Diameter of the slider contact which sweeps comb conductors is smaller than the spacing between comb conductive teeth. With closed contact record d the teeth of the two edge contacts in the change are connected electrically with the continuous pickup shoe path. If it fails, there are 2 options: Either you ask Günter user althase for new cams and replace them. It is most often easier to isolate. Personally, I think a two prong tool would work much better for obvious reasons. If it isn't working the engine will run just about as well as with it working, in fact you can totally unplug the throttle switch plug and barely tell the difference. If you notice a change in engine speed, you have a vacuum leak.
