Check engine light refuses to go off after engine replaced

My check engine light has been on since 2014. I'll try to make the story short. In 2014 my oil light and check engine light came on. Got the oil changed & took car to dealer for engine light. They said no oil was in the car & that the other place probably didn't change it. They put oil in the car & reset the lights. About a week later lights back on. That same week engine locks. Tow the car to the dealer. They say engine needs to be replaced due to sludge. They blame me & say I didn't do enough oil changes. I need my car so no time to argue. I get the engine replace

2006 Ford Mustang has check engine light on

ANSWER : There are countless potential causes for your illuminated check engine light. The mechanic manually turned off the light, but it came back on because the problem has not been fixed. The first place to start is retrieval of the stored diagnostic trouble codes (DTCs). These codes serve as a starting point for any further diagnostics a mechanic may perform. Codes will be stored anytime the check engine light is on. Since the first mechanic was unable to fix your concern, I recommend giving the professionals at YourMechanic a call. We offer expert check engine light diagnosis and repair.

ANSWER : It is possible that you could be having an issue with your powertrain control module. This is somewhat of a common problem on many GM vehicles. I would recommend having your vehicle inspected by the dealership to determine if the powertrain control module is functioning properly. If not, a reflash of the powertrain control module may resolve the issue but often times it must be replaced.

check engine light O2 sensor already replaced same codes still popping up after replacing old O2 sensor

ANSWER : Hi there. What you received from the parts store was a code retrieval, not a diagnostic. The codes are set when a fault is detected against normal operating parameter. The computer does not know what caused the fault, only that the fault meets the criteria for this code to set. There could be a problem in the wire harness, converter, or the ECM. The code and data are needed to properly assess the direction that a diagnosis needs. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a check engine light inspection.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light

ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit. For more help with these electrical tests, contact our service department.

Engine replaced, check engine light on again

Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?

Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken.

I recommend replacing the oil pressure sensor then checking to see if the lights will go out.
