look behind the glove box, there should be a sticker with the code on it. or in the owners manual if you have one.

SOURCE: Emmission codes, Mass air flow sensor

The P0101 code is indeed a code indicating an issue with the MAF sensor. It could be something as simple as cleaning the sensor, or it could be faulty and in need of replacement.

Now, the P1870 code refers to the transmission, and a condition in which the PCM is detecting excessive slipping. That is to say it perceives the transmission slipping as it compares engine speed (RPM) and vehicle speed (MPH) and should a ratio be exceeded then the PCM will set code P1870. I would expect that you would notice a bit harsher shifting in response to this code, particularly on the 1-2 shift as the PCM will command higher fluid pressure to combat the slipping.

Now, it is possible that the an issue with the MAF would cause signals to the PCM to change significantly and to such an extent that the PCM would think something is off with the transmission, so I would start there, with the MAF sensor and see if that helps as it appears you were already thinking.

Let go with your theory

You get a PO102 MAF code.( Mass Air Flow Sensor)
Lets say the sensor is somehow not working correctly,and as you say,it has spark and fuel

I would guess, you think, the engine would be happy, having no idea how much air it is getting. Kind off like the computer will somehow overlook it is controlling an air pump in the first place.

CODE PO102 after Mass Air Flow Sensor replaced


Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.

Whenever the engine light still comes back on after that, there probably still is some (other) problem ...

P1298 Code Fuel/Air Metering


Are you sure you wrote the correct code. According to Honda, P1298 is a high ELD circuit voltage. If what I just put is correct, Honda has a service bulletin as this is a common problem( it could be another fault, but this is the most likely choice).
The ELD has a bad solder joint. I have done several of these, you will need to replace the ELD, and this is how.

1 D/C the negative battery cable (make sure you know your radio code, it will be needed to use the radio again)
2 Unbolt the fuse box that is in the engine bay.
3 Attached to the fuse box underneath there is a plastic cover, remove this cover.
4 There is a 3 pin connector under this cover. Remove it
5 Flip the fuse box back over, there are 2 big fuses bolted down, a 40 A and a 80A
6 Under these fuses is the ELD, remove it and pull the bar that sticks out of it.
7 Stick the bar in the new ELD
8 Put everything back together. Do the idle learn (just idle the car for 10 minutes with no loads on such as radio, headlights etc..)


This is probably the first thing they will do if you bring it to Honda assuming the code you have is P1298.
