Engine trouble code po1151


Hello, This code indicates you have problems with an O2 sensor. The sensor should be on Bank2 and should be the sensor closest to the exhaust manifold. Causing a lean condition.

Check your wire connector to this sensor and the wires leading from it. The defect is saying the heating circuit in this sensor is defective. This can mean the wires going to the sensor are burned or the connector is dirty. Or the sensor is just plain bad.

You can get your scans free at Autozone, Oreillys, or Advance and you may want to have them clear the code after your repair.

DTC shows up on computer at auto zone as a bad code and i dont know what DTC means so i cant fix it if i dont know what it means so my question to you is what in the world does DTC mean ? Im working on a...


DTC stands for Diagnostic Trouble Code. My question is why did you have the vehicle checked out in the first place? Is the check engine light on? What was the code number and did it start with P0 or P1. If you don't remember then have the code(s) cleared and operate the vehicle until the code(s) reappear. The code or codes can help you to determine where to start looking.

1998 ford 4.7l runs too lean po1151,po171,whats this mean and how too fix,hesitates when i punch it and back fires


Could be a bad mass air flow sensor. with the engine off unplug the sensor then test drive with sensor unplugged.(you can do this with almost all the sensors on this vehicle). It will replace the sensor data with a default parameter. If problem persists check fuel pressure.
