    Exclamation I have 10 CELs, NEED HELP

    Hey, okay so I went to Meineke to get my car diagnosed with a genesis since I had a cel, followed by major problems: 1) Car struggled to turn on, 2) When finally turned on I pressed the gas pedal and it turned off [when turned on again I waited for the engine to heat up and pressing the pedal didn't cause it to turn off] 3) It had an 1.5-1.7ish idle, 4) when I put it in first to drive off it had a hard time to accelerate properly even with me pressing it all the way, it felt like I was lightly pushing the pedal [i shifted before 5k rpm because at the point it gave a scary jump, in second gear it still lagged until it hit 3k rpm and the car ran normally from there on (driving normally of course), 4) when driving fast the car choked off and on, and 5) while driving the car turns off sometimes. Well I believe that's all the problems

    My car was diagnosed with 10 cels, idk about you guys but thats ALOT for me. These are the codes:

    -P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input

    -P0118 Engine Coolant Temperature Circuit High Input

    -P0122 Throttle/Petal Position Sensor/Switch A Circuit Low Input

    -P0123 Throttle/Petal Position Sensor/Switch A Circuit High Input

    -P0508 Idle control system circuit low input

    -P1086 Tumble generator valve #2 (LH) position sensor circuit low input

    -P1087 Tumble generator valve #2 (LH) position sensor circuit high input

    -P1088 Tumble generator valve #1 (RH) position sensor circuit low input

    -P1094 Tumble generator valve circuit #1 (opencircuit)

    -P1096 Tumble generator valve circuit #2 (opencircuit)


    The specialist from Meineke said that the cel p1086 might be causing the erroneous idling, the engine stall, and the poor driving performance. He also said to replace the TGVs and position sensors, while I was in the process of doing that (had an extra used manifold in trunk with the one TGV(the other one is broken) and 2 position sensors), so as I took the IC off I noticed I had a hose(short) that wasn't connected, I tried to find for a good 15 minutes where it would connect to but nothing, then I noticed that the hose was connected to the TGV on the right, so maybe that could be the problem, but I really don't have the slightest clue where it goes, maybe i'm missing something. Btw this is a used engine I bought, the mechanic put some parts of the old engine(which explains why I had an extra manifold [belonging to the bought engine] in my trunk) that we're better than the one I bought, well thats what the mechanic said. But maybe I just need to connect that hose, or replace the TGVs and sensors, idk, thats why I seek constructive help here. And yes I did my research, none was help I needed, or maybe I didn't understand thoroughly. Okay so here are some pics I took of the hose, one of the tgvs, one of the position sensors, and the tps I replaced(hoping it'll fix cel p0122). Click on pics to enlarge.









    Oh and my mods are: Custom Catback Hi-Flo Race Exhaust (3" piping + 4'5" tip tilted upward left), Blitz SUS Power Air Intake Filter. F1 Racing Stage 3 Clutch Kit, Blitz Dual Turbo Timer DC IV, and Blitz Super Sound Dual Drive BOV. So please help me, thanks.

    He was the one that told me the problem, I then later discovered it, he put in my engine for free, and you know ej20s are a hassle, but he doesn't know where the hose goes either.

    Almost sounds like the manifold harness is disconnected.

    Yeah, and did you verify that the manifold harness is connected?

    Alright look, for you to have 10 CEL codes either all of these sensors have failed, or they are not getting a signal to the ECU. Find a few of these sensors and verify that they are actually connected back into the wiring harness that goes back to the ECU. I would bet that whoever installed your replacement motor failed to plug in a connector.

    Start educating yourself on how your car works and learn how to troubleshoot it the thing, or take it to a COMPETENT mechanic who can. There are many people on this forum that can add insight and guidance, but to expect someone to trouble shoot your busted car over the internet is quite a bit far fetched.

    Well I'm not expecting anyone to trouble shoot my car over the net, I'm expecting that they already understand what I obviously don't.

    It's most likely an electrical problem. Check all of your connections, make sure everything is crimped, latched, or otherwise fastened tight with the appropriate connectors. Trace all wiring away from the intake manifold to their end points and make sure nothing came undone or was burnt up.

    You're ECU is recieving signal from somethings, but not from others. The rough idle and accelaration is the computer trying to compensate.

    Okay, basically what others have said, so I'm outnumbered, I'l try that. But how do I know if my mechanic plugged the things right, how do I know if its burnt? will it be black is that just a figure of speech? Since it's most likely an electrical problem, does that mean that the unconnected hose connected to one of the tgv's is meaningless (if confused refer to pic)?

    Sorry, I can't view the pic while I'm at work, but I'll try to check it out later.

    The TGV's are actuated using the motors on the side of the tumbler housings. I'm not sure where that hose is supposed to go off the top of my head, and without actually being able to see it. I'm looking in the service manual right now, to try to track it down for you.

    As for a burnt wire, it would be charred black and broken. If your car ran correctly for a long time, it's pretty indicative of a correctly swapped car. Something just broke or became disconnected, and now it's time to track it down.

    I'll post again when I find what I'm looking for in the manual.

    Here is an exploded view of what should be connected to your TGV's, this is from the manual for the 02-03 WRX's.
