i follwed this https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/how-pull-cel-d4-srs-abs-codes-code-lists-1901557/ , and i got a code 13 ,atmospheric pressure sensor. What is that????

 

Also it idles like at 1.5k and when i give it some gas it acts like if it was gonna shut off , could this be because of the cel?

 

To my knowledge, in all USDM ecus, there is the PA sensor which measures the ambient barometric pressure in order to compensate your fuel mixture accordingly (if say you live in the Colorado mountains, you can't likely use the same mixture as living at the sea level beach of florida).

I'm not sure, but this may be the sensor you are referring to.

 

i restarted the ecu and im not sure if its a code 10 or a 20

 

Code 10 is one long blink in a continual repeating pattern. Code 20 is two long blinks with a longer interval between each double blink. I am assuming that you have code 10 for the IAT sensor. Check whether it is unplugged.

 

Everything is plugged in but now it idles around 300 rpm's , i extended some wires on the engine harness but i carefully did it one by one , could this be the problem?

 

Do you have code 10? What wires did you extend? Did they happen to be for the IAT sensor?

 

if thats the one on the intake mani then yes

 

Bump for some answers

 

The IAT sensor is inserted into the intake pipe. It has two wires that are Red/Yel and Grn/Blk.

 

Well if he has a z6, its on the back of the intake manifold. I believe its a two wire sensor.

 

This is making me believe you are reffering to the MAP sensor. Manifold Absolute Pressure sensor. This is the sensor on your intake mani right after the throttle body. I believe its a three wire sensor.

 

EJ8 = D16Y8 engine, unless he has a swap. Did i miss that he has a D16Z6 engine?

 

the car is an EJ8 but im running a b18c but there no plug on the intake pipe like other cars , it was running fine before that. maybe a bad conection when i extended the wires?

 

Heres a video of the cel

Your video is private. The IAT sensor is attached to the IM of the B18C engine:

 

this is y i thought he had a z6....but anyway, the vid is private.

 

video fixed , yeah that was the sensor i was talking about , its in a diff place cause im running a skunk2 mani but anyway i think i did extended the wires fot it , could this be the problem?

 

The code is 10 for the IAT. There's a problem with the extended wires.

You should put these details about your car and engine into your signature.

 

^ x2 ...how did you connect the wires? i.e. twisting them together & electrical tape, butt connectors w/ shrink wrap? double check your connections.

 

cut/soldered/heatshrinked

 

It seems that this may have been covered by the others but I'll add this anyway...

, if you extended the IAT wires (which is located on the intake manifold), that seems to point towards your code 10 issue. Check your wiring extension soldering/splicing handiwork. Issues can sometimes occur if say... you used organic core solder to splice the wires instead of rosin core solder (this can lead to problems down the road figuratively). Another possibility is during the rework, the wires were flexed enough to cause fraying (possibly even within the insulation). Another possibility is if you used the soldering irons like 'cold heat', these irons use electricity to melt the low resistance solder which could damage circuitry within the ecu or IAT. I guess the more promising option is that the solder didn't 'wick' up the stranded wire well enough and just snapped under low tension stress.

Take all these as you will, all I'm saying is I think you have found the most likely location of the problem at hand.

Good luck!

 

Use a multimeter to test the two wires for a short or open. If the wires are fine, check whether the IAT connector is receiving 5 reference volts from the ECU.

 

I will take a look into that tomorrow , Thank you

 

Alright , will do
