---- '''Navigation''' * Main MembersPage/KoabiBrooks * Idle MembersPage/KoabiBrooks/Idle * Ignition MembersPage/KoabiBrooks/Ignition * Injection MembersPage/KoabiBrooks/Injection * Trigger MembersPage/KoabiBrooks/Trigger * Wiring MembersPage/KoabiBrooks/Wiring * Q&A MembersPage/KoabiBrooks/Questions ---- '''TRIGGER PAGE''' ''at the request of Marcell :)'' I plan to use a VR crank position sensor from a Jetta (ABA engine code). I am getting rid of the distributor and placing a coilpack in its place, so the Hall sender won't be used as it's integrated to the distributor. The ABA crank position sensor part # is: 021 907 319B The ABA trigger wheel on the crank is a 60-2 wheel. Here is a tool to help get some variables about your trigger wheel. PHP by me, the math by MembersPage/GrmRacer. http://www.starshadow.com/~koabi/carstuff/cranktriggers.php ---- The connection has 3 pins - * ECU signal * Signal Ground * Shield Ground Here are some notes from Marcell about determining the correct pins moved from another page: * one goes to ground (resistance to other 2 pins > 2 MOhm) => this is shield (connect to GND) * two pins go to the ECU. Resistance between the latter two is 540 Ohm in both directions => VR confirmed. (VR is usually 450..900 Ohm). http://www.80tq.com/~wiz/gallery2/d/35-2/Sensor+-+VR.png ---- Misc Notes: *Checking for wheel errors: Manmlp04mll mll to refresh, bye to end session (try until BYE is echoed back from term). *Perform resistance check from shield pin to engine with the sensor unplugged from harness - if there is continuity, the shield should NOT be connected to ground on the ECU side. Otherwise, the shield should be grounded at the ECU side. *Sometimes shield not connected to a ground works, as well *note to self: "Fuel pump on after inactivity" was 0.5 - now set to 2.0
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
