Knock sensor, code P0330

Hello Danny,

I decided to take it to a reputable shop to have them further diagnose and fix that trouble code and/or sensor, once they scanned it with a tool they said code P0330 didn't show up, instead it's a P1521 with the other 3 codes I already knew about. Is it possible that the car is showing a code that isn't there? I just went ahead and rolled away but should I go ahead and assume that the sensor is okay? Thanks!

Hi!

Yeah, I usually take my car to my nearest Dodge dealership for my oil changes because it's almost the same price if I did it myself with oil and a filter and it's much quicker. I'm pretty sure they're using the right velocity of oil at least it's what it shows on the sticker they put on my windshield, they don't ask what oil type I want but I just figured being a dealership they'd know what to do, someone said I should be using full synthetic oil because of the age and mileage but I'm not sure.
As for the o2's and catalytic converters the person that owned it before me messed with the catalytic converters and the whole exhaust system and messed up one of the o2 sensors post cat on the driver side, the catalytic converters are also messed with pretty bad and welding was very bad, I think it has a slight exhaust leak but I've already had it looked at by a performance car expert and he said I'm definitely losing some power but until I can afford to deal with it I should be fine, I'm planning on having the entire exhaust system redone soon, from new headers to exhaust tips.
As for the knock sensor the code came up on the dash like in the video, but when I took it to a shop they said they didn't see the code on their scanner, the engine runs and drives and idles very smooth and there's only the roar of the engine, not really any other noise, except when it's cold it'll vibrate slightly but it goes away, my acceleration is funny at times and I just had the transmission rebuilt recently so I'm not sure if it's from one of the trouble codes or something else.
I appreciate all your help guys, let me know what you think! Thanks!

Yeah, he did look at them for a good minute. He seems to think that maybe they've been gutted, they both look like they've been taken off and put back on. He said they should be fine until I can get something done on them. The 02 sensor on the driver's side was messed with pretty bad, the bong port for it has another one brazed on top of it and he said that's going to keep it from getting a good reading. Hence the one code and the other code because of the cats possibly being gutted or whatever was done to them, he said the 02 that's throwing the code shouldn't effect performance it's the pre cat 02's that do, but I think my car is good example of someone messing with the exhaust possibly trying to gain performance and sound but doing more harm than good. He said he's seen worse, but the car does drive good and idles smooth it just has funny acceleration at times, does it sound like it'll be okay just for a few months? Let me know, thanks!

Hi Danny!

Sorry it has been awhile. I still have the trouble code for wrong oil type. I checked with the dealership on the type of oil it's supposed to have (i.E. Conventional, synthetic etc.) And they looked it up and they said it calls for conventional. So what should I do? Could it be a sensor? Thanks!

Thanks Danny,

When I went to have it changed on the 4th I made sure that's what they were putting in it, as far as I know it's running the same as always. I feel the engine vibrate like something is kicking on then off at say a stop light. I figured it's the mds, other than that it runs good.

Hi Danny,

Yes, the check engine light is still on, and the one for the oil type remains.
I recently took it to a shop to have the valve cover gaskets and spark plugs replaced and I talked to the head mechanic there about it, I told him I take it to the Dodge/Chrysler dealership for its oil changes regularly and that I asked them if they were putting the right oil in it and that they did look it up and it called for conventional, he said he's had a couple of car's like mine in there with a wrong oil type and a oil temperature code and he changed their oil with I think he said semi-synthetic and it took both codes away, so maybe I should try that? What do you think?
Thanks for all your help!
