Crankshaft Position Sensor — Snapped Off During Removal (2 Viewers)

[davisfj62]

As the title of this thread says, yup you read this correctly, I snapped off the position sensor (CPS) when trying to remove/replace it on my 1998 LC 100. Even though I was being very gentle the flange literally crumbled in my hands as I was backing out the sensor. This is most likely why I was getting error codes and my rig was running poorly.

Has this happened to anyone else on this forum? I'm trying to put a plan of action together and I figured I would start here. There is zero room to get any type of extractor in place to help remove the remaining main element of the CPS. It looks like I can gain more room by removing the oil filter and oil cooler housing. Can someone DM me with the step-by-step instructions to remove oil cooler housing from the manual?

Any help/insights would be most appreciated.

Thanks,
Jeff

Worth keeping that site around...it's basically every service manual for the 100s.

Edit: kickass design work, by the way.

I don't know how it could be stuck in port (casting bracket that's part oil pump). Since it, has a great deal of space around the CPS in the bracket port.

Be very careful. Bracket CPS is in, is part is oil pump casting. If frozen in, consider pulling lower timing belt cover. Then clean out space around CPS, soaking in P-oil (ATF works well), possible just a little heat and tapping out (very gently). Sometimes the long road, is safest, cheapest and fastest.

Thanks for sending this image and input. The plastic flange (just below where the electrical pigtail connects in your photo) was so worn that it disintegrated when I removed the 10mm bolt that secures the CPS in place resulting in the majority of the CPS being stuck in port.

I was hoping not have to disassemble the front of the engine (I literally just did the timing belt last spring). I recall that to remove the lower timing belt cover I have to remove the fan shroud, fan clutch, serpentine belt, upper covers, etc...

I need to pull up some videos to recall all the steps.

Thanks again

I've never seen one stuck or crumbling.

I don't how yours looks, so can't help much. Other than I'd get creative to remove, without pulling t-belt cover. Perhaps a long wood screw, tap in to get a hold on, pull out.

If doesn't work, pull covers.

It's so tight in that area that I removed the oil filter, oil cooler and brackets to gain better access. Now I have room to work. Later today I plan on drilling a small pilot hole and inserting a small double-side wood screw/bolt. I'll then use an oversized socket (make-shift pulley puller) and back out the broken CPS.

...and if it doesn't work, I'm pulling the covers. Fingers crossed amigo!

Fixed. Thankfully, removing the oil cooler assembly gave me the access needed to drill a small pilot hole. After drilling the pilot hole I inserted a flat head pan srew and pulled out the broken CPS on the first try. I replaced the large O-ring and figure eight o-ring, did an oil change and replaced the coolant. Sure appreciate everyone's help.
