MIL on code PO452 set. Clear with scan tool and it resets immediately. Evap sensor replaced with fuel pump, no better. What needs to be done next. -
Answer 1
clearing code never fixes it. you need a diag from a shop that knows what to look for. you need a scanner tool, vaccuum pump, meter and voltage source to properly test to find defective part Roy -
