I've tried other places with no real answers... So I come here in hopes of less sarcasim and more knowledge.

So after getting my b16 in the car and starting it I got a swamp of codes.
code 3: Map
code 6 Water Temp Sensor
code 7: TPS
code10: Intake Air Temp

Everything is pluged in and it all worked fine before replacing the bottom end. Now all of a sudden I get all these code. I replaced the Water temp sensor in the thermostat houseing and nothing happened, And the gauge still doesnt work. When I unplugged the MAP the Car still ran, Same when I unplugged the TPS (With car running)

Ideas please?

 

what kind of car, what engine harness are you using and is the b16 jdm or usdm?

 

Make sure you didnt put the wrong plug on any of them. I'm not sure about MAP and TPS use the same connector, but ECT and the VTEC solenoid do, and they are very close.

If in doubt check the wrie color.

 

MAP and TPS do have the same connector i believe. try swaping them.

 

Since you did the thermostat...did you re-connect the grounds?

 

You talking about the string of wires going to one eye hole crimp the bolts too the housing using one 10mm bolt?
If so then yes, I even took a peice of sand paper and cleaned the surfaces on both and reconnected them

 

Well is there any chance that you broke any wires or smashed them?

If not then you need to check to see if you are getting voltage to the sensor and then check the output. You see where I am going......

 

I do see what your saying, I just need to find a multi meeter now

 

Could a Leak at the intake manifold cause all these problems?

 

thesmogman is probably right. It's common for multiple sensors to share the same power feed so if something is wrong with that wire, all the sensors are effected.

 

Anyone know where the splice be in the harness where they all connect?

 

Check the helms, its possible there is not a splice but that they all come from the same powerstage in the ECU. See if the ECU has individual pins for each sensor supply.

Did you make sure you had the correct connector on the sensors? I've seen this 100 times.

 

Well its time for an update, And lol oh boy is this a funny one.

So I went over everything that everyone explained to try to find the problems, And with no luck.. Nothing worked. So as I sat there staring at my engine trying to think what in the hell it could be, Little so I see a wire kind just sticking up.. So Im wtf took a closer look and guess what. the wire to the Intake Temp sensor is broken. So I get a new connector and repin it, connect it, dis-connect the battery for 10 mins, re-connect, Start and to my suprise no CEL!

for some reason thats all that it was.. Maybe you were right and its all circuted? Idk but there gone now.

Thanks all that help

 

Still doesnt make snese unless it was broken and grounded on a bolt or the tranny or something.

 

Noop, wasnt touching anything. It was just sticking upward... The harness Im using is from a 95 Cx if that makes any difference IDK But thats all it was.

 

Good eye

As for the other sensors the only thing that I can come up with is with it disconnected the other sensors might have been getting too much voltage from the 5v feed and their output voltages were not what the ECU was expecting.

I hate it, and like it when it is something simple!

 

Thanks bro!

As though its still weirod to me how one sensor can threw off others unless there circuted? Idk lol
