Pulse Generator ?

[m-dtech]

ETK Part No 12141710668 (item no1 in diagram)



is there any way to test this part ??

No spark from the car and everything is new..

[mrLEE30]

crank sensor knackered will give same symptoms.

not sure about pulse generator. where does it go to or from in the engine?

gearbox to ecu, its early motronic system

there are two, speed sensor and crank sensor iirc.

Don't think theres a way to test it, substitute another and try.....

[dazleeds]

pulse sensor wont make any diff to the running at all

its only used for the diagnostics

have taken them off totaly before and all runs perfect

Intresting.

Isn't the picture of the crank sensor?

The pulse sensor is attached to one of the HT leads (No.1 I think)

They both connect at the bracket holding the diagnostics plug.

the early cars had the two sensors on the gearbox..

the latter cars had on the ht lead and front pully.

regardless...

all i need to know is is there any way to test with a multimeter ?

one sends a pulse to the ecu which in turn pulses the coil to give spark.
(so im told)

is yours the earlier or later model?

resistance between terminal 1 (yellow wire) and terminal 2 (black wire) on sensor side should be 860 to 1060 ohms. resistance between terminal 3 and either 1 or 2 should be 100 000 ohms.

on the later models resistance between 1 and 2 should be 500 to 600 ohms

on the later models resistance between 1 and 2 should be 500 to 600 ohms

Actual measured value I use is 540 ohms between the two pins nearest to the lead.

pmsl, i posted the part i was querying even the ETK part number

so basicaly im looking for 500 ish ohms failing that its fecked.
