While traveling between New Orleans and LA in west Texas currently. Before leaving Nola emissions system code came on P0175. Couldn’t get part in time. Yesterday on Highway sped up to pass, the truck jerked and started misfiring turns out it was spark plug in cylinder 5 found mechanic they changed the spark plugs. Hours later when getting to San Antonio same code came back. This morning I found a mechanic who changed the O2 Sensor upstream for bank 2 which is what has been reading with this code. Go to pull out of shop truck gives me a keyless starter issue code. After starting and stops g a few times it goes away. Hours into the drive to El Paso I got a warning light for transmission overheated. Stop immediately and let it cool. Call a Honda dealership guys tells me last time he saw that it turned out to be the fuel injectors. It happened once more on the way to El Paso. The transmission has not shifted erratic, it has not showed Overheating on the dash, I do not see any leaking and the radiator fan is running. Here now and talked to Honda dealership going in first thing in morning for diagnostics but wondering if anybody has suggestions.

This sounds like the MAF sensor needs to be replaced. When this sensor starts reading incorrectly it will not give a code for it. Also, I would service the throttle body. Here is a generic guide to help you step by step with instructions in the diagrams below to show you how on your car:

Here is more info on the code:

The P0175 code is a generic diagnostic trouble code (DTC) that indicates a problem with the fuel system in Bank 2 of the engine. More specifically, it points to a rich condition, meaning that the fuel mixture in that bank is too rich (has too much fuel) compared to the ideal air-to-fuel ratio.

Thank you for the advice. Spark plugs changed, upstream O2 sensor bank 2 replaced and diagnostics ran at a Honda dealership for overheating transmission. Nothing wrong with transmission. I was told I was driving too fast, for the amount of weight I had in my truck at the exterior temperature it was. Next day I drove slower with no problem.
