I've attached a picture of the sticker on the underside of the hood. Also, when I switched out the MAF I had removed the keys, and disconnected the negative lead on the battery. After swapping it, I drove it down the street and back and those were the new errors.
To make matters a bit more complicated, we have seen California cars here with stickers that do not say California. Having California on this sticker just proves that the car is CA. Not having California on the sticker does not prove that the car is not California. Anyway, it takes a while for the ECU to cycle for new codes. Normally about 10 minutes driving at 50 miles an hour, then letting off of gas and coasting to a stop. Again, I would (IMHO) start over, as you are getting codes from the different components you are putting in, taking out, etc. I would put in what actually belongs in the car, then pull the dome fuse for 60 seconds, go out and drive for 10 minutes and 50 mph, let the car heat up properly, foot off gas, coast to stop, then pull your codes and see what is really there. Then the ECU will give you proper direction. So far all the codes that you have pulled indicate a high voltage issue of some sort, going to various sensors. It is possible that this is a voltage issue from the ECU. Going back to the original code 53, you may just want to check on the engine block by the distributor, to see if you have that ground circuit from the ECU that attaches there. It should be a brown/black wire, a ground, easy to see.
ok progress, a FED car, so it has nag light. and switch.
good, you did the parts switching correcty. few do here, but you did.
as you know i cant see you ,, LOL good !!!!
YOU must not have the CALIF ECU. as shown above. what tranny you got.
3sp, 4sp or 5sp?
if those are FRESH codes then they are real.
only 2 possibles for all 3 to go high like that.
1: the ground wire to sensors stated is open.
2: 02 shorted as stated from heater side to CELL minus side (a gross short)
3: ECU bad, most likely bad CAPS.
unplug the o2 and drive. if you get those 3 fails then its not 02 shorted in side
THANKS for photo it will be added this PM to my TAG page.
Bex is trying to get 51s,,
the reason i need the ECU pn is simple.
if its the correct ECU and it throws 53s then the ecu is bad or you have
a bad ground to ECU or a bad power to ecu.
or a short from 12vdc to the ECU that is ILLEGAL.
like 02 internal short. like i said,that is a very very bad short to have.
and it amazes me the many that report , oh my the o2 wires are all melted.
funny stuff. fixing cars and not inspecting all wires at sensors and ECU.
that stuff is easy, and if not corrected ,diagnosis is not going to get far.
