In trying to possibly diagnose and finally repair my car. Some of you have mentioned to me I should check my hall effect sensor/wiring/connections.

From everything I have read on here and elsewhere on 1986 Chrysler Lebarons with a 2.5 TBI-non-turbo, the Hall Effect Sensor should be "in" my distributor?????

Dis. Cap off, rotor button out, and the distibutor is "hollow" like the inside of a coke can!!! I wiped down the inside of the distributor, and cleaned off a little carbon on the "new" rotor I put on in May.

Now, granted I am blind as a bat, but exactly where is this Sensor and how small is it? Is it up UNDER the distributor??

I even went and bought a Chilton book for 1981 to 1994 Chryslers front wheel drive 4 cylinders.

It shows exactly where it is for 1981 to 1985 FWD 4 cyl, 2.2 and 2.5L but nothing on a 1986 Lebaron. (My Luck!)

Can anyone help a dumb ole Tennessean. Seems all the info I read contradicts each other. The Chiltons book fault codes for my year of vehicle doesn't match anything on Allpar or Knize or Chrysler K-Car Forum.

I now know why when I take it in to the dealer or a mechanic they can't fix the problem because the info that is out there conflicts.

Any help would be appreciated as always.

Thank you.

Check the link in my signature. Those code descriptions are accurate for sure.

The HEP (Hall Effect Pickup) is under the distributor cap. For the TBI there is one connector at the end of a wire coming from below the cap which connects to the harness. This looks like a black disk. Without the HEP the 'walls' which spin as the distributor turns won't create the signal to fire the ignition and injector.

To detect a totally failed HEP disconnect the battery then once reconnected try to crank the engine. If it doesn't start pull the codes. If code 11 shows up it means that the computer did not receive any signal from the HEP indicating that the HEP is dead.

However, if it does start then the HEP may still be bad as in intermittent. But there is a possibility that it is a connection where the HEP connects to the harness.

Take off the distributor cap, pull the ignition rotor, and this is underneath. This is the Hall effect pickup, and it just lifts out:

Follow Bob's instructions. I had a '86 LeBaron GTS with the 2.5L and yes, it does have a HEP - at least I remember mine having one though I never replaced it. Remove the distributor splash shield, remove the distributor cap, remove the distributor rotor and the HEP is right there - can't miss it. At least it should be right there.......

If it still isn't there, can you post some pics? I don't recall a 2.5L ('86 and newer) ever not having a HEP.

I think I still have a Haynes manual at home for the '86 LeBaron GTS/Lancer. I'll try to remember and see if I can look this up.

Been this way since 81 for 2.2 onwards and 1986 for 2.5L as well. Either carb or TBI.

Note that carbed HEP is smaller diameter than TBI. That what I found out.
