Hi, my name is ***** ***** I will be happy to assist with this today.In some cases, I may need more info to assist better.I apologize for any delay.
I am here Sundays through Thursdays from around 5 am to 2 pm Mountain time.If you respond and I do not respond back right away I will do so as soon as I can.

Is the P0102 code still coming up as a current fault code with this issue here?

Is it blowing out black smoke out of the exhaust?

Was anything else checked or tested with this fault at all?

Let me know, thanks, Pete.

Customer reply replied 2 months ago
Still don't have an answer. Gave you all the information I have. Truck won't take gas like it should. Chokes off. New mass flow sensor 2upper and lower oxygen sensor replaced new. OBD codes, p-135 p141 p161 p155 p443
Ford Mechanic: Pete, Auto Service Technician replied 2 months ago

Did you inspect the wiring harnesses leading from the oxygen sensors to see if any wiring was found to be an issue here at all?

Have not taken it back to mechanic
Customer reply replied 2 months ago
What should I do.next
Ford Mechanic: Pete, Auto Service Technician replied 2 months ago

All the codes that are set here indicate a fault with oxygen sensor heater control circuits.If there is an issue with the wiring harness leading from the sensors to the engine computer this will cause this fault and the wiring will need to be checked and repaired to resolve this issue here.

Also, check and make sure all fuses are good in all fuse panels.If a power feed fuse is blown this can cut power to the heater circuit.If you can verify the engine liter size in your vehicle this will help as I may be able to look up what powers the heaters for the oxygen sensors.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service, your 5-star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.I work on delivering the best answer and help here but in some cases, it can be difficult to do without seeing the vehicle.

Thanks Pete
