S40 will not run. Over 5 MPH after recranking, is this a bad crankshaft. Sensor

Had a bad crankshaft sensor go out while driving. Would come back in 5-10 seconds and drive fine. Everything else still worked but no throttle when it went haywire. This went on about 10 different times going about 50 mph. Ran codes at autozone that help narrow things down. It had 5-6 codes at the time. Picked that because I got lucky

Could be crankshaft sensor or cam.

If it's stalling out at times did you check the crankshaft position sensor? That usually happens to Jeep vehicles a lot for some reason or another.

Two items to check. The crankshaft sensor will reduce fuel pump pressure if it miscounts the RPM. The plastic strainer in the fuel tank can break apart and clog the pump intake in the tank. When the engine quits, the fuel pump is stopped and the loose particles are returned to the tank bottom.

In either case, try checking the fuel pressure at the test tap on the fuelrail.

Bad sensor. Also check crankshaft sensor.

overheating? low oil in crank case?low coolant ,maybe have catalytic converter checked if smells like rotten eggs!!!

Check the codes, you should find that you need to replace the crankshaft position sensor and/or the camshaft position sensor. You can take it to most auto parts stores and they will put it on a meter and run the code test for you.

It surely sounds like you are confronted with a damaged cat converter. The o2 sensor is what triggers your ck eng ligh and it is located both up and downstream of the Converter. Won't hurt to have it chk'd. If there is a sulphur odor coming from the exhaust, The cat conv is bad. Good Luck, Ned

Code 42 is the (asd) automatic shutdown driver,there is an open or a short in the relay circuit, and I don't have my manual to tell you where to look, have it checked.
Code 11 is no distributor signal during engine cranking.
Code 12 is battery power to computor disconnected in last 50 to a 100 cycles; memory standby power lost.
Code 55 is end of code output. These are what my code manual is showing. That shutdown driver should be checked. Hope this helps.

I would replace the TFI ignition module and or the stator, these are the most common issues, you didn't say whether it had a loss of spark or fuel pressure, so just going on my 20 years of Ford dealer background.
