My car was running fine till I clicked on the security it went to hell from here..
It was idling like it was on LSD hehe. I loaded the greddy setup at 7psi.

my car is showing 3 codes they are here:

ELD CIRCUIT HIGH VOLTAGE P1289
SERIAL COMMUNICATION LINK MALFUNCTION P0600
SECONDARY O2 CIRCUIT HEATER CIRCUIT MALFUNCTION P0141

please advise on what to do. my car is a 92 civic vx TYPE S Swap with a Rev Hard Turbo Kit Stage 2. http://www.wiredspeed.com/itemdesc.asp? ... HK-20KCIV1

I have 3" piping and 550cc injectors.

please help a newbie

Disable OBDII functions and the multiplexor to remove your codes.

thanks a lot admin.

anyways I have a new check engine light engine is over heating code.

maybe I should raise the temp on the setting to slove this problem..??

let me know Hondata.

thanks a lot.

Datalog and see what temperature you are seeing, both cold and hot. It could be that you just need to bleed the cooling system.

Please tell me you did not swap out the K20 coolant sensor for the civic sensor.

it was not overheating before. it goes on and off.
yes I am using the correct sensors from the k20.

223.5 F

what can be causing it..??
please find out for me ..

You've got the car - time to work it out. if the car is actually overheating and then 2. what is causing the high ECT reading or why the engine is overheating.

Bleed the coolant right on the outlet from the cylinder head (I put a little bleed screw in mine). Check the ECT sensor in ice water and almost boiling water to check 32 and 212 degree readings. If your engine actually is overheating, better find out why fairly quick.

well the funny thing is the temp guage on my cluster is normal!!

and but the ecu throws the check engine light

what you think... is their a option on the kmanager options to raise the temp..??

If you are seeing 232 degrees, there is a problem. Either the engine is over heating, or the reading is false, but you need to fix the problem. I have outlined what areas to look in above, but you do need to address this. Raising the overheating threshold in KManager is not the right solution.

yes I don't know the reading might be false. why I think this is because my cluster themp guage is reading normal. I am not trying to fuck up my motor nor my turbo, today I did the following bought two gallon of Type 2 coolant from dealer. Flushed the system like this. Opened the drain valve ran tap water through the radiator. Filled that baby up with Coolant like the helms says. Turn on the car with the cap not on tight. Let the fan go on for two times. shut of the car then add coolant. This looks like didn't solve the problem. I am stumped. Why is the ecu reading its over heating and my guage is reading normal..??

anyone know what is the normal operating temperature. because before I didn't have this problem with this engine over heating...

what you think Hondata. maybe I should try it your way...??

max temp was 228 degrees on the log. what does this indiciate false perharps?

thanks a lot man for your help

You're not very good at following instructions. Ok, my last attempt.

1. Test the ECT sensor with ice water and boiling water.

2. Bleed the cooling system (which is different from flushing it). Make sure the cylinder head is bleed from the exit on the flywheel end and that no air remains in the system.

3. Datalog and post the results here.

Normal operating temperature for a K is 180-190 degrees.

yea I know I tested the ECT sensor its fucked soo will be changing it tomorrow. sorry but I followed the helms manual to change coolant and bleed the coolant system acroding to the helms. anyways I test the sensor the ECT its bad. I will be changing it tomorrow and report back.

thanks much data.

now the temp is between 190-203.

I think it has been fixed.

thanks a lot data

looks like we used the old sensor from the 256,000 mile civic

it looked fucked up lol. thanks much bro

same problem again

this is with a k24a2 swap in a DC2 the fan is not working thus causing it to over heat. but read on..

the temp guage on the cluster is reading normal but the computer is reading temp 223 with the laptop connected.

hondata why is the temp reading normal "on the cluster" this is both with my eg and my dc2. If anyone doesn't know their car is overheating.

say this happens the user doesn't know his throwing the code P0217 he keeps driving the car his guage will stay normal until ban blown headgasket!!!!!!!!!!!!

please advise!!!

How are both the ECU and gauge temp sensors wired? What is the actual temperature of the engine compared to the datalogging?
