If you have a distributor it would be the little sensor near the protruding blades.

I got this free Pdf manual from reliable-store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 years

The link below is a good resource to find the meaning of your codes. The E41 code is listed here as P041 or (E041).

code 91 does not exist

Hello: Here is a breakdown of the codes you have: 888 is the segment check which tells you the system can display all codes, E-52 tells you the battery has been disconnected. It tells you that an idle learn should be performed. This idle learn is a very long procedure, you need a Service manual to perform it. The F-31 means there is a communication problem between the fuel data panel and the BCM (body control module). Most likely a Fuel Data Panel, but it could be wiring and/or a intermittent BCM. It would require intensive trouble shooting. 7.0 means the self diagnostic system is ready to go to the next step. If you go to Auto Zone or Advance Auto Parts you can buy a manual for your car (about 20.00 Dollars) I would like to be of more help but what you have requires hands on troubleshooting.
