Code 23-Idle switch (throttel valve switch) Signal circut open
Code 34- Knock sensor
Code 45- Injector fule leak
Code 51 Fule injector circut open
Okay so code 34 is obvious, swap out knock sensors and done deal
but what is all this circut bs????
and open circuts?
fule injector leak? that means open injector right? But how would i be able to find out which one? And how is the circut open? ugh im so lost
Are you sure its giving you code 34? Your buying a MAFs, TPS, an injector and I'm assuming o-rings for $50? That's a damn good deal, lol.
Oh, btw. I just double checked the codes. Code 13 is not the MAFs, its the CTS. Recheck the codes and see if you get a 34 again. My guess would be you got a 33 and just mistook it for a 34. 33 is the o2 sensor.
Your correct on all the codes except the Code 13, which is the Coolant Temp Sensor not the MAFs. What I would do first is make sure everything is plugged in. Make sure nothing accidentally came loose throwing a code. Once you do that, clear the ECU. Supposedly you can clear the codes just cycling from Mode 1, 2, 3, 4, 5 and back to Mode 1 but sometimes it doesn't work. I would disconnect the negative batt terminal, press the brake pedal a couple times and let it set for at least 5 minutes. This should clear your ECU of any fault codes.
After 5 min, reconnect the batt terminal and start the engine. Let it idle for 1 minute on the first start, don't rev it or anything. Go for a test drive and if the check engine light comes on, see what codes pop up.
Just for reference, he's a list of SOHC ECU codes take directly from the FSM. I honestly have no idea how your getting 23, 34, and 51. Is it the stock ECU?
Look at the sticker on front and match the numbers to this chart. For example the ECU in the picture is a A11-B44-G70 and goes to a 91 Manual / Federal (non cali) 240sx KA24DE
i was too busy to re write numbers but illl try to do it tomrrrow.
i want the CEL gone already.
Weird thing is that every since i sea foamed my car the check engine light comes on and off atleast 15 times a day (not exsaterating) depending on how much i drive it comes on and off
here is a video

So aft swaping ECUs. Getting code 55. Resting then i finally get a code that makes sense.
Code 32. Because before i ever sea foamed my car the light was constantly on. Now it goes on and off. So....How to fix this problem? I was thinking of just sea foaming again. But thats not good. But im going to the junk yard tommorrow. I know i need something to swap it out but idk what?
With the engine running, reach behind the intake plenum and push the EGR diaphragm up (careful, it'll be hot if the engines warmed up). If the EGR is function correctly the engine will choke a little bit and start to stall. Also, make sure your EGR solenoid is plugged in, and check the vac lines as well. Here's a pic of the EGR solenoid.
everything is plugged in and nothing happenes when i push any of the lines, and none are cracked or anything. So do you think you could find me one sitting around?
EGR thingy does not function. Just tested. Have any for my single cam?
