2001 Mazda Protégé 2L 4 cylinder. I did a search but didn’t find an answer. When I did a scan this morning there were no codes but some systems showed “Not Ready”. The engine was cold.
If I check my system with my OBDII scanner is it necessary to check with the engine at normal operating temperature or can I check it when it is cold?
Right now no CEL and all seem fine but I just want to see the readings. Thanks.
