The P507 code shows up frequently when someone sets the BISS for a higher than stock idle, and the Idle Control Stepper valve no longer has enough adjustment to bring a high idle down to a target idle...

Another possibility its the ICSV is "Frozen" (siezed or damaged) and it can no longer properly adjust, and its stuck at a higher than target RPM (1500 or so)

on rare occasions, addon devices such as turbo timers or piggybacks can trigger this code, but that doesn't happen often.

 

i got this and started to freak it was teh p0304 misfire on cylinder 4. calle my tuner and asked me what the weatehr is like. -3 outside at the time.

went down reset the code. and hasnt come back yet. after about 200 miles. i dont drive my ix that much.

 

looks like it came back

 

im P0710
that it is the problem?
what is dangerous to drive?
thank

 

The usual reason the “Service Engine Soon” light illuminates is due to something related to emissions on the engine failing. The insufficient EGR flow will cause higher tail pipe emissions. The P0300 random misfire (if real) may allow raw gas to go to the exhaust and raise the level of emissions. So, a SES light is usually not something to be panicky about unless you face an emissions check that allows no codes.

However, let’s say the engine temperature sensor fails and indicates to ECU that the engine temperature is -40 degrees and you live in Key West. The engine may not start because the starting mixture will be way too rich. The P0300 code also sometimes causes the ECU to go into a funky mode that anyone who has experienced it does not like. However, Mitsubishi says this is not a problem.

 

I have the code P0133 come on ( I week earlier I had code P0139 and code P0171). The only code that comes on now is P0133.

 

Hi guys, i have the same problem, today I install the injen UICP, injen intake pipe and the Gredddy EBC, i start the engine after i hook up everything and the Service Soon Light came out, what could be the problem?
I clean the MAF with a CRC contact cleaner from the inside because was dirty, did i mess up the MAF with the conctact cleaner? i did that before and didn't have any issues.

Can someone help me

Mod are:
Nesei LICP
Still have the stock ECU without a flash
Apexi Intake

thanks
