My car just throw these two codes, something about the crankshaft positions sensor A circuit. Can someone tell me what's going on??? Thanks in advance...

 

Had mine when Vishnu installed the HKS cams and gears. I reset it using the OBD scanner. I increased the idle. It has not come back and seems to be OK now. I also have the V3 for Xede.

 

Sometimes a non start condition will trip that code. I don't think it is really anything to worry about if the car is ideing ok, but if it keeps stalling out, you may have some problems

 

Well, I had these once, cleared them and they never came back. If you've replaced your cams and/or cam gears, make sure they are dialed in correctly. Read the directions very carefully and follow them. When my gears were installed they were done correctly, went back to the same shop, had 272/272 installed and the cam gears got set 1 tooth off, which is 12deg retard.

Lopey idle, the occassional stall (maybe 5 in the three months I was driving around thinking ... "just need a tune") and only threw the two codes (same to codes) once, about 5 hours after picking my Evo up from the shop.

Bottom line is you have to pay attention to the installation of the cam gears ... if you've got the Vishnu cam gears and your gas mileage bites the big green weenie, you've probably got an install problem on the gears. There were two Evos this weekend with same lobey idle, same gas mileage problem, and Vishnu cam gear installation problems.

Thanks for your replies, I've the stage 1+ for 10k already, never throw these two code before. I had problem starting my car due to low battery (mini battery). After I charged up the battery and get the car started that's when it throws the codes. I cleared the codes and it hasn't come back so far. Hope this is a one time thing...

 

Does your V3 Xede changed the car's startup, I mean it crank a little different...

 

Yes it cranked a little differently compared to the XFLASH stage zero plus, which is the stage I was before. Every morning it starts up with no problems. I can hear the fuel pump humming also. I noticed that it will stall only if you are at stop and try to steer all the way (left or right). It seems like losing the vaccum and the idle. I already have increased the idle by adjusting the idle screw. I also notice the stalling, with all the conditions above, happens when the wheather is hot. Right now it's been raining here in the bay area and so far I have not stalled.
