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]

this could acually be the end to this thread, mmm i took a closer inspection and the wires that hook to the coil packs at the bottom, i took all of the old electrical tape off and found that 2 wires where either melted or chopped a little and where barley hanging on, so i fixed it drove it and no CEL drove fine so im now going to see about getting a new fuel filter and get the timeing done.

now for a quick question on the thermostat houseing there are 3 connectors on it, the one with the 2 little hoses comeing off of it, a green thing with a wire comeing off it of, and at the bottom there is a blue one with a wire.

what is the blue one? cold start?

[IHateHacks]

The blue one on the bottom is the auxiliary fan sensor switch.

The one in the middle (mine isn't green) is the A/C coolant temp sensor.

The one on top is the BVSV. Bimetallic Vacuum Switching Valve.

The cold start injector time switch is on the water outlet housing, its the one on top with the brown connector. The water outlet housing is what the thermostat housing bolts to. Then from there the middle one on the water outlet housing with the green connector is the ECT sensor (Engine Coolant Temperature for the EFI). Then the one on the bottom of the water outlet housing is the sensor for the stock temp gauge on the dash.

hmm do i need the blue one connected because its hanging on 1 little wire to, needs to be redone.

If you want your aux. fan to work then you need it.
