My check engine light flashes 13 times. and stops then flashes 72 times and stays on for a long period then it does it again. I just changed the oil and i washed the engine compartment. I know my tranny is going out but still shifts pretty good, Could i've messed it by washing the engine compartment?
Code 13 Barometric pressure sensor

If you brought your car to Honda for service, they probably forgot to reset the maintenance reminder. If you took it to another shop, they probably did not know how to reset it. Anyway, the reset procedure is:
Put your key in the ignition
Turn the key to the II position for a couple of seconds
Then turn the key to the off position
Now push and hold in the odometer reset button
While still holding the odometer reset button, turn the key back to the II position
Hold for I think 10 seconds or so and your maintenance reminder light should reset it self.

it is the Transmission Control Unit. you have to find the reason why the TCU is flashing the D4 fault code. not replace the unit. have your vehicle scanned for another code. your transmission or transaxle is giving you a warning that something is wrong .
SOURCE: code PO131
Code PO131 is O2 sensor circuit low voltage , bank 1, sensor 1. That sensor I would say is the one in the exhaust manifold. I would check voltage to the sensor from the computer. If the voltage is not 5 volts, then it could be a computer problem or a wiring problem. I have seen factory wiring and connectors give a voltage problem. Check for a damaged or burnt, pinched wire. You need to know for sure that the voltage is correct to the sensor. Intermittent problems are hard to trace , but patience and knowledge helps.

You have a bad transmission control module (TCM). It is under the passenger side front floor mat. You can get rebuilt units off Ebay, whatever you do, don't get a used one! They are all bad. If you know anybody that does electronic repairs, you can have them replace the big 220 uf capacitor on the PC board in the TCM. It's a two dollar part and a ten minute job but you have to know what you're doing.

P0740 is a Torque Converter Clutch Circuit Malfunction, you will need to have just this circuit tested, it is mostly just a defective Torque converter clutch solenoid in the trans or a defective connection to the trans, u do not need another overhaul.
