STOP ENGINE light. N14 Celect. Most common causes?

Red flashing lights mean active faults, yellow mean inactive.

If the sensor wire plug has a jumper wire connecting the two ends of the plug to complete the loop then your fine, but if the wire plug doesn't have a jumper wire at the end then that's your engine code because the wiring isn't completing the loop therefore it thinks there is no coolant

 

Engine position sensor is between the top of the oil pump and the block, under the air compressor. It has a flat four wire plug. If it's been replaced usually the sensor wires will be white black red and green. It takes a special socket to remove and install.
I had one a few years ago that would not start unless it was ethered and wouldn't idle under 11/1200 rpm. They will do odd things.

 

Plug is right at the sensor maybe 4/5" of wire. The plug is above or near the front of the power steering pump

 

If the lights are not blinking after you use the diagnostics switch you have no codes. You reset the ecm by removing the power from the ecm.

The three critical errors stop the engine but reset after the problem is corrected.

The engine position sensor cannot be disconnected and have the engine run. The Celect is a primitive ECM but it won't fire the injectors without the timing signals.

If you were having position sensor problems you would have both 115 and 121 codes and maybe a 111 code.

More than likely what happened is the wiring where the low coolant sensor was bypassed has a problem and wiggling it made the connection.
The longer term solution is to spend the 20 bucks and five minutes to fix it correctly.

Also, there should be a fused cable going directly from the batteries to the ECM. Removing the fuse will reset the ECM without disconnecting and reconnecting the cables.

 

If you unhooked the battery, you reset the codes. So now you won't have any until you drive it for a bit.... Checking wiring for things that don't make sense will be a headache, my n14 had a few wires that just seemed to sit there and be for nothing..... Take it for a drive and see if you can get the code back.

As was stated it can't hurt to buy a new coolant level sensor and pop it in. For the couple bucks it costs, may as well do it.

 

Engine position sensor will fail with out logging a code. I have had this happen several times. If you have access to an ohm meter I would run it until it shuts down then test it.
