Something is fishy. I was not able to find a 202 code for an OBD2 compliant engine. So I would assume it was p0202. When I google p0202 code it came ups"
"Code P0202 sets when the Power Train Control Module or PCM sees an open or short in the #2 cylinder injector circuit."
Did the shop tell you the code and what it was related to? You need to get the correct code. If it is an injector circuit code, they should be looking at the wiring. If the motohome set where rodent could chew the wiring, wiring repairs would be necessary.
If you have an Android phone or tablet you can buy a "ELM 327" OBD2 reader module (with
Bluetooth) from Amazon for between $10 and $100. Once you have the module download the "Torque" app (free or $5) and read/clear codes. Plug the module into the OBD2 port and Bluetooth pair it to your phone/tablet and read the codes and system information. It makes a really inexpensive reader.
Spend the $5 for the app and you can build a dash. Almost anything the PCM (Powertrain Control Module) has data on can be displayed with the app.
