Hey what’s up fellow ranger dudes my name is Tim I’m new here. I don’t exactly know how this works so I’m just gonna state what my issue is. I got a 2001 ranger 2.5l about 6 months ago I dropped a new used motor (2.5l with 87,000 miles) in my truck. After putting everything back together the truck runs great, but my. Check engine light is on I hook up the obd and it spits out 5 codes
1. P1451- Evaporative Emissions system vent control circuit.
2. P1506- (IAC) valve duty cycle higher than expected (I replaced the IAC)
3. P0135- O2 heater circuit bank 1 sensor 1 (I replaced this sensor)
4. P0141- O2 heater circuit (bank 1 sensor 2) (I replaced this sensor too.
5. P1409- egr vacuum regulator solenoid circuit.

i replaced 2,3,and 4 and check engine light is still on spitting out the same codes but the truck runs great. Has anyone encountered these challenges while working on ur ranger. Any feed would be greatly appreciated. Thank you guys.
