what code is minor exhaust leak?

Question

minor exhaust leak on a 2001 ford explorer sport. fuse was blown for CEL.. same fuse for cig lighter. had 3 codes.. exhaust leak.. don't remember what code number but never noticed because CEL didn't work. P0731 for first gear ratio wrong but I just had the tranny replaced 6000 miles ago. should I change fluid and filter? P1000 for a test not completed for emissions

Answer 1

An exhaust leak can caused many codes, is better if you check with a scanner what the code is so you don't guess what the problem is.

Answer 2

P0731 incorrect gear ratio first

P0731 this can be a internal transmission failure or friction material, 6000 miles this is still a young transmission,Fluid and filter may not help with this condition, internal condition can just be a stuck off shift solenoid,or a non working shift solenoid, As for the exhaust leak, The code you might have is a lean bank code,P0171 or a 02 heater circuit code, rarely are these cause by a minor exhaust leak, As for monitor not completing with these 2 hard codes you will just code up unless corrected.
