It's the blower motor resistor BECK/ARNLEY2040019 {#GE6R61B15B} www.rockauto.com/en/catalog/mazda,2001,protege,2.0l+l4,1374072,heat+&+air+conditioning,blower+motor+control+module+/+resistor,6557.
Thank you guys for your suggestions. I know is a PITA to remove that sensor because I've done it once, years ago and now I guess it's time to have fun again 🙂.
Thanks pcb! You think the Ultrapower brand will do it for a DD (not a long commute, 50-60 km only) and do you remember the size and where to get that insert you have to use to keep p0420 away?
Hi guys. I got this code p0140. I know what this is and does not seem to change anything in engine’s performance. Now my question is: what is the easy(cheapest) way to get rid off check engine light?
Any help is appreciated.
