I've observed some symptoms in my Volvo 740,..whet I take the hall sensor for the hand and I've moved them, the hall sensor isn't stiff,but I can move it for all sides. It's normal or something is broken?? I've got same problems with start hot engine and I think, the engin is in good condition,but it haven't got enough power and accelerate beyond 120 km/h is very hard.
I've got B230F with LH 2.2 system form 1988 year.
all the best....

Any one know something about it or not??? Please give me some answer,..because I can't find anything about this in net.
I'm a little confused by your description, the hall sensor is either screwed down in the distributor, or screwed into the bellhousing, I forget which but '88 is right around the transition. What do you mean by it not being stiff?
OK,..sorry,..is my mistake. Now I know that it isn't hall sensor, but only conector of hall sensor, which is inside the ignition distributor. This black connector, is not stiff,....but I can move them for all sides. It's plastic thnik and I've heard that sometimes this connector have broken,..but it isn't hall sensor - sensor is inside the ignition distributor.
Tell me,..because mechnics said that in this engine (B230F) the ignition is ONLY controlled by EZK module, but most of people said that in this engine I can set the ignition by the hand (use a stroboscope lamp). The ignition is controlled by: knock sensor, hall sensor, EZK module and underpressure,..but the main set ignition I must put by the hand (manual set in the ignition distributor) and then all the sensor and underpressure set the ignition in detail.
Sorry for my english :))
That connector breaks fairly often, it's quite fragile. If it sticks in the hole then it's ok, if it's dangling by wires then the connector needs to be replaced. You can order it separately, they refer to it as an insulator, the electrical pins in it can be removed and transferred to the new piece.
The EZK module is the brain, it uses the knock sensor, hall sensor, and load signal from the Jettronic ECU to adjust the timing. You set the static timing with a stroboscope by rotating the distributor, assuming this car has the hall sensor there rather than the later crankshaft sensor which is not adjustable.

In this car I think I've got hall sensor in ignition distributor (because I've got this broke connector in the distributor,...is connctor from hall sensor, isn't it?). So in this system, the main set of ignition is made by stroboscope, and the sensors adapt the ignition in detail?? Am I right or not??
In this system is connected the underpression to EZK to stering ignition??
My problem with start the hot engine can be, because of bad ignition set?? or the hall sensor is going to damage??
Thenks so much for answers and help me.
all the best...

What is diffrent between EZK 116 and EZK 117?? How can I check which system I've got?
Yes, that's correct, the ignition control box adjusts the timing from the base setting, advancing or retarding it in response to knocking, engine load (vacuum), and other factors.
It can be, if the hall sensor is not working, the fuel pumps won't run when you crank the engine. If the pumps do come on then the sensor is good.

I've got LPG Gas in my car,...this symptoms is in the both fuel - NoPb and LPG, so in the LPG the fuel pump is not working.
Well all I'm saying is that if you're set to petrol, and you crank the engine, and the fuel pump runs, then the hall sensor is working.
How's your engine wiring harness? When my '87 died it had no spark, I thought it was the hall sensor, but it turned out to be rotted wiring insulation in the bundle of ignition and injector wires under the intake manifold.
OK,.in the patrol NoPb car starts,so the fuel pump is OK.
The wiring and the spark plug are new.
