I'm receiving the codes in the Title^^^^. (06 Scion tC**) I recently had someone replace my clutch, but it was ok until I ran it through 2 ft tall water. I could feel a lack of power/ jumping while accelerating afterwards. The car died and wouldn't start until the next day. My engine also rattles a bit when the ac is on but I think this is due to bad motor mounts.

I really don't think its a leak, but maybe the O2 sensors got wet? Could the O2 sensor alone trigger all these codes? (I replaced spark plugs recently)

Can someone advise where I should begin?

It's showing too high voltage on your MAF sensor. Do you have a cold air intake that goes to the ground? Maybe it sucked up some water and shorted out the sensor. Also check your air filter.

It shows you are running lean, that could be linked to your MAF sensor or it could be linked to your vacuum leak due to your EVAP leak. EVAP uses vacuum to suck fumes from the gas tank into the engine, if a line breaks then the sealed system is openly sucking in air that it may be unable to monitor. This usually effects our idle and could cause your lean issue which may also be why you are getting random misfires. Not only are you sucking in unmonitored air, but if your MAF sensor is shorted then it's not reading the monitored air. Also your Intake Air Temperature sensor is showing high voltage. I would check the connections of everything before replacing it. If you are lowered, 2 ft of water is a huge bit that could have splashed around on different electrical components, and as we all know electronics and water do not mix.

I can't thank you enough for the insight! I replaced o2 bank 1 sensor & sparks plugs. Check engine light hasn't came on sense. Does this seem strange or could my replacements really resolve all the codes I posted above?

I don't see how that would fix an evap code. Unless the O2 sensor shorted, but I wouldn't know how that would short the other sensors.

Hmmm, gotcha. So well after 50-100 miles the check engine has came on today.... again. I'll have to look into the MAF. Will post here if I'm lost again!

Update: Changed spark plugs, o2 sensor, and bought a new gas cap. Before the gas cap I was only reading evap codes(p0455, p0441, p0456) but I haven't drove it much since the new cap. I think this will resolve the most recent codes but I may need some new exhaust tubing? TY to everyone!
