code 14 and 52

[west_side_supra]

well hi again everyone, as the subject says i got a code 14 "ignition and ignition coil circute/ignitor and ignition coil/ECU" and code 52 "knock sensor"

could the 14 be setting it off the code 52, say in the case that the coil wasnt working properly and causeing the engine to knock <creating the 52?!?!? if this is the case i have another coil pack

[west_side_supra]

ok well i have put new plugs and replaced the coil pack redid the ground and im still having a code 14 and 52 what the hell is going on

[mrnickleye]

But you haven't given us enough info to really help.

Does the engine run good?

Does it run good on the test drive??

Any stumbling or misfires??

Hows the idle??

it does stumble it drags as if i just lost 100hp ill floor it and the turbo spools the motor makes the wwwaaahhhh noise but it dont the body just dont move very fast. like a spark plug isnt going or like talked about in a previous thread injectors. but if its the coil pack not working properly that would make just as much sense.

that is a random good/bad. sometimes its good and will idle 600-1000rpms but when i run it hard or rev the motor high it will drop to about 200rpms almost die and then recover itself to about 400-600.

im really getting tired of this issue.

oh and one last thing, i have noticed that the cam gears arent at the same possition. one of them is 1 tooth off. should i fix this and how?

[west_side_supra]

was that not enough, go ahead and ask i got answers besides why its doing this to me

[supramacist]

When was the last time you gave the auto a complete tune up???

And checked the timing?

[west_side_supra]

i have been wanting to give it a tuneup since i got it. where should i bring it, just to a dealership or something. or should i just do it myself? the only thing i have done to it tune up wise was plugs and wires and new coil, oil/filter. what else should i do.

i dont understand the how to check the timeing on a DOH im use to working on my old 79 camaro. chain driven. unlike the supra which is a belt.

[supramacist]

Distributor cap and rotor and the air filter also need replacing. You may want to go to your dealer and by a t.s.r.m. toyota supra repair manual. They are engine specific and cost about 75 bucks but it is the same book the techs at the dealer use.

What type of coil are you running and what plugs did you choose?
What wires did you get? I'm just curious.

[IHateHacks]

First of all there are 3 coil packs on the 7MGTE. Did you just replace one or did you replace the igniter? The igniter is not bolted to the engine, it is bolted to the drivers side inner fender, its the aluminum thing with a couple fo harnesses coming out of it.

If the crank pulley notch was lined up with the 0 degree mark on the lower timing belt cover and one of the cam gears matchmarks didn't line up with the notch on the inner timing belt cover, then yes you should fix that asap as it is definatly not running right. You are going to have to take the timing belt off and reinstall it the correct way. Hardest part about that job is getting the crank pulley off. The rest is easy, took me 5 minutes to install my timing belt.

Well you first need a timing light. Hook up the positive cable to the positive on the battery and hook the negative to the engine block where the negative battery cable attaches. Connect the signal clamp to the No. 1 spark plug wire. Then you need to disable the electronic advance by bridgeing terminals T and E1 at the diagnostic connector. Then start the motor. Aim the timing light at the crank pulley and to where the timing marks are on the lower timing belt cover. The notch on the crank pulley should be lined up with the 10 degrees BTDC mark every time the light flashes. If its not, then loosen (don't take it out) the 12mm bolt that holds the cam position sensor on and spin it in whatever direction will make the notch line up with the 10 degree mark. Push down on the cam sensor to advance the timing and pull it up to retard it. But install that timing belt properly FIRST before you set ignition timing because you will be wasting your time with the incorrect valve timing set.

As far as a tune up, the fuel filter is the #1 most overlooked item when performing a tune-up. And a little tip, don't bring your car to a dealer unless you want to get ripped off, period.

7MGTE's use a DIS ignition system, they don't have a distributor only the non-turbo GE's have that crap ass old technology.

i replaced all 3 of them. i got them from my donor engine. the odds are low that the coil packs where broken on that to but it is possible. but highly unlikely. so what check the igniter?
