Suggest to purchase a relatively inexpensive scan tool that works w/your car. That will read the diagnostic codes. And you’ll have it to read any codes posted in the future. I think simple aftermarket code reading tools are priced less than $100. If you plan on doing your own diagnostics, or asking for help on computer forums like this you’ll have to have access to the diagnostic codes to make much progress. There’s 8 sensors plus the battery to replace otherwise. And that might not solve your problem.
