I love my carbureted 86 Mazda, no computerized bs to go wrong. EMP proof too other than the battery.

Magnets are weak on cheap ones, and when you do this clean your connections with electrical cleaner wd40 brand is good, do this with the battery disconnected and give a good 5 minutes and shake it to get any excess out, i hosed mine out pretty good, it dries fast but this is just being safe before you put power back thru. If your having problems not starting afterwards, unhook both your battery cables and touch them together but do not let them touch anything, wrap them with tape if you want, it'll drain residual energy from the electronics and drain capacitors. Let sit few hours or even over night. Also had an issue connectors clicked but didn't Click with a clean sound had grease and grime not letting the lock really set. Can use a multimeter and check your wires, 12v power and around 5-10 on signal wire, middle should be neutral, 3 wires. Should be pretty standard for most cars

I have a replaced the Crankshaft Angle Sensor three times and each time the small magnet approx 1/4 had detached from its glued position with no other physical damage to body of the sensor, each time the magnet was retrievable. The sensors were purchased from the dealer and from Advance Auto Parts, the results were the same lasting one or two years. The installation in very time consuming due to the sensor mounted location to engine behind the timing belt. The vehicle is a Kia Optima 2.4l.

I have a 2007 Chevy equinox and they made this vehicle from 05 to 09 I think. I’ve change the crank sensor and had problems cause wouldn’t start ruff idle and cut off. The point I’m getting at when you change the crank sensor replace it with the exact part manufacturer that came out from the vehicle not all manufacturer wire there crank sensor the same.

I have a 06 Nissan frontier and check engine light indicated cam pos sensor needed changing. Changed all 3of sensors, 2 cam and 1 crank sensor. Unplugging the cam sensor was frustrating and irritating cause we couldn't get it off but finally did. Once all Nissan OEM sensors were installed engine light went off. But now truck takes a long time to crank before it starts

I just replaced the crankshaft position sensor on my 99 Dodge Ram & it’s still having the same issues! I’m so mad cuz that crankshaft sensor was a Bitch!
Hopefully it just needs to relearn or I may need to do camshaft sensor too 🤷‍♀️
