I am just about at wits end here;

2005 Base
5spd
swapped in used motor with 60k miles
Throwing knock sensor code
p0328

Replaced with original ks from my original motor, code still thrown
New plugs, new wires, coils from old motor ( worked fine before it blew)

I will add that the sensor on the OMP had broken off one of its screw holes. Took to mazda to see about a replacement, they do not sell just the sensor but told me It would be fine epoxying the wing back on.

Will a KS code, cause the engine to go into limp mode?

Symptoms;
wont go over 5k rpm in neutral or during drive
can not go faster then 15-20 mph

My cat is not clogged, I unbolted it and tried to drive quick, same results.
Did the NVRAM and KAM resets
I have searched and searched, maybe im not using the right keywords or something.

Does anyone have any idea?

It probably has nothing to do with being so disorganized and unprepared that you can't even report the code or condition properly

The engine is in limp mode any way so that is probably the least of your issues

A service manual would help, you clearly don't have one or aren't using it. You can always spend more money to play the unnecessarily replace more good parts guessing game.

i have not paid for any of the parts i have swapped over so you my friend have no place telling me that I am spending money on parts. When I did say i swapped the parts from my blown motor. Thank you for you help, please do not respond again.

The fuel injectors were connected on the new engine, did not mess with anything.

If someone can be KIND enough to give me a few keywords, I will do the research on my own. If you would like to be a DICK, end yourself, and do not post here. Thanks.

OH by the way, the code is P0328

Found this thread and copied the fix.

Here's the problem. Looks like I had a rodent eat through one of the OMP stepper motor wires while I was on vacation.

Now, anyone know how where I can pick up a new connector or splice this wire?

ok after some more research.

I have found the the OMP position sensor can cause a limp mode problem. Correct?

I did remove this sensor as it had a broken wing, which mazda told me would be fine to glue back together and re-install. Assuming I did not put this sensor back in correctly, that would be a cause for the engine to go into limp mode. Am I correct?

So the solution to the problem would be to adjust the OMP Posistion sensor?
And another question would be, does the knock sensor code (p0328) throw the car into limp mode.

Before anyone (teamrx8) decides to be a dick, the reason I am asking this question is because I do not have the time around my 60+ hour work schedule to tear down the motor to replace the wiring harness if it is not causing the car to go into limp mode.
MY MAIN concern is why the car is in limp mode. If the knock sensor does not put the car into limp mode then I will fix that problem when I have the time. I think i remember reading that the KS in our cars does very little to the engine. Hence why i would rather spend the little time I have adjusting something that can get the car out of limp mode, rather then swapping the harness only to find out that it wasnt the reason the car was in limp mode. Yes the harness will get swapped out, as I believe that is the reason the KS isnt working ( and for that I THANK you teamrx8) its just that the KS not working properly isnt my main concern if it isnt causing limp mode.

hope that makes sense.

You only get to choose who responds to your problems by keeping them private.

Search: limp+mode

Get a service manual, either in paper or online

Read, read, and read some more

P0328 is high input voltage to the knock sensor. If it is not the sensor itself then the only way you can have high voltage is if there is either a wiring problem or there is a PCM problem

Change your attitude. I am not your enemy unless you make me one in your head, and even then it is only in your head. I am no more a dick than you are a clueless muffinhead. Losing focus will not solve anything.

wow u just bitched at Team .... he is probably one of the most knowledgeable member here ...

He is as welcome to his opinion as anyone else. It doesn't make any difference to me one way or the other. I've been on forums a long time and have seen the same situation over and over. My comments are not just for him, but for anyone who may follow in his footsteps. There are steps and procedures to follow on a modern car. The hillbilly wing it parts swapping method will likely yield little or no results. Not communicating properly already sets your asking for help down the wrong path. Not having a service manual or access to one means chasing your tail and a forum full of pointless replies that solve nothing.

I am a dick; a dick with a purpose. A drill seargent is a dick who wants to keep your *** alive in a combat situation. Did you learn that the stove top burner is hot because somebody told you or because you burned the crap out of your hand? Just like the puppy that needs to have its nose rubbed in its own poop to be house trained we are all no different. Some people can learn the nice and easy way, but by and large most of us learn the hard way, including me. I gave up on the nice easy way a long time ago because by and large people just stay weak and helpless by having stuff handed to them free and easy.

You can educate people without being a dick. It just takes a thing called "finesse". You might not have finesse, though, if you really did learn the stove burner was hot by touching it.

Thank you! And Team as I said in the post before hand, I THANK you, i looked through the service manual, noticed this and hence why I said, the harness will be getting swapped out when I have the time to do so. I just want to get it out of limp mode. If the KS isnt causing it to go into limp mode then that is not my main concern.

My main concern is why it is in limp mode, and from researching, again THANKS to you, I have a good reason to believe it is in fact the OMP position sensor, because I did remove this sensor to repair the broken wing.

Yes, you may be very knowledgeable, you may know and understand these engines more then I do, but unless you change your attitude, none of that really matters. Since your only replies have been overcast with hints of "I am way better then you sarcasm." Again I still thank you somewhat, but would appreciate it if instead of telling me I am hillbilly replacing perfectly good parts when indeed you really have no idea that that isnt what I am doing, rather you could just say, "Search this and this, or try this keyword. Instead you decided to reply with this.

"It probably has nothing to do with being so disorganized and unprepared that you can't even report the code or condition properly

The engine is in limp mode any way so that is probably the least of your issues

A service manual would help, you clearly don't have one or aren't using it. You can always spend more money to play the unnecessarily replace more good parts guessing game."

You could have easily left out the first line and the last sentence of the last line and gotten your point across without sounding like a dick. Still I will say I am sorry, and again thank you...

And indeed the OMP position sensor was the problem. Car is out of Limp dick mode, and running great. Minus the KS CEL, which I do believe the wire harness is the culprit. I assume the car is Ok to drive for a little bit with the KS CEL on, granted I put nothing but 91 or higher octane in the car. If someone can confirm or deny that it will be okay to drive for a week or so until I can get a spare moment to tear it down and swap out the harness. Until then I will search for an answer.

TO Team, although you were a dick, in the end it was you who had helped me with my problem. SO to you personally, THANK YOU. And please do not take offense to my comments. I will quote one of my favorite movies in regards to you being a dick.

Please if you have a small child in the room ask them kindly to leave
