Sensor a crankshaft


A crank sensor is an electronic device used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.
The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the pistons and valves in the engine, which is particularly important in engines with variable valve timing. This method is also used to "synchronise" a four stroke engine upon starting, allowing the management system to know when to inject the fuel. It is also commonly used as the primary source for the measurement of engine speed in revolutions per minute.
Common mounting locations include the main crank pulley, the flywheel, the camshaft or on the crankshaft itself. This sensor is the most important sensor in modern day engines. When it fails, there is a chance the engine will not start, or cut

How do I set injection pump timing


you haven't given which make , model,year of engine type of fuel pump, make of fuel pump and the only clue is the flywheel
the injection timing mark is normally denoted as a lightning symbol and you will find it anywhere between 14 degrees btdc to 22 degrees btdc
or it will be set at the degrees btdc r recommended by the manufacturer
It has to be exact because after that mark will be down on power and too far advanced will melt pistons

1984 300 ZX. what would cause the right bank not to fire. I have spark at the plugs, 150 psi of compression, fuel pressure, I can pull all 3 plug wires on rightside and it will run


Multi port injection or throttle body? If it is multiport, maybe right bank injectors are not pulsing. That could be an open in your injector wiring circuit. That's all I can think of. All cylinders on right bank have a strong, blue spark? Anything else exotic, like variable valve timing?

Hi guys. I have a 91 pajero 2.5ltr turbo diesel. Looking for the safest but best way to get a bit more grunt out of it.any serious answers will be greatly appreciated. Cheers. D.


check that the turbo is operating as it should be Variable vanes actually moving -actuator connected and hose in good condition. Have the fuel pump serviced and have it recalibrated to a couple of % over specs. Have the injector tips replaced and the pressure set .
Check for dragging brakes pads rusted on the calliper slides. Consider the tyre sizes that you have . Have the fuel pump timing professionally set to get the correct ignition/injection point

Transit pump code p0216 how can i fix this


P0216 DTC - Injection Timing Control Circuit Malfunction and this means the diesel fuel injection pump has a timing failure. This could be that the injection pump timing needs adjusted OR the failure is internal to the injection pump and therefore non-adjustable.

NOTE: If your vehicle is a Dodge Ram with Cummins engine then be aware that fuel delivery problems frequently cause this code. Prolonged fuel delivery problems can cause injection pump failure!

Symptoms of a P0216 DTC may include:
Low power
Crank, but no start
Hard start
Displays an intermittent stumble or miss
Engine may start and then stall
Engine may appear to drive fine but surge at idle


The most frequent cause of this code is a bad injection pump due to poor fuel delivery. Fuel delivery problems could be:
A plugged diesel fuel filter
An in-tank blockage
Air in the fuel due to a cracked in-tank fuel ine above the fuel level
Bad transfer (lift) pump
Injection pump out of time


Possible Solutions: First, simply check if your injection pump timing is adjustable. If so, check the timing and adjust if necessary.

If you think that you may have a fuel delivery problem, then check the lift pump operation. On Dodge Ram with the Cummins engine, the lift pump should produce about 45 oz of diesel in 25 seconds of operation. This can be performed by disconnecting the fuel hose from the injection pump and pumping the fuel into an approved container. Bump the engine over but do not start it. Then the lift pump will operate for 25 seconds. If the fuel is aerated, then check/repair fuel line and recheck.

With the fuel hose connected the fuel pressure should be 10psi. If the fuel delivery tests fail, replace the diesel fuel filter and recheck.

If it still fails then verify there are no restrictions in the fuel tank

Then replace the lift (transfer) pump. IT SHOULD BE NOTED that if this code surfaced after a routine fuel filter replacement or if you have any of the above symptoms after routine fuel filter replacement, then suspect the fuel transfer pump. This occurs because even a weak transfer pump can still provide enough fuel for the engine to run. But when the fuel system\'s prime is lost due to fuel filter replacement, it may not restart again without fixing the fuel delivery problem.

If you found your injection pump to be bad, the lift pump should be checked for operation to protect the new injection pump. This is because weak or low output from lift pump are common cause of injection pump failure. There are some aftermarket kits that can be purchased to warn the operator when the fuel pressure/volume drops to level that could damage the injection pump.

Hope this helps (remember to rating this free answer and leave a testimonial comments).

How the ECT SENSOR WORKS


The ECT (Engine Coolant Temperature) sensor is a thermal variable resistor (also known as a "thermistor"). The ECT delivers a signal to the THW terminal of the Engine Control Module (ECM) which varies with engine coolant temperature. The ECM uses this signal to control the fuel injection system, the overdrive operation on vehicles equipped with electronically controlled overdrive transmissions, spark timing control, idle speed control, fuel pressure control system (if equipped), heated oxygen sensor system (if equipped) and EGR systen (if equipped)
