Hi there,

(From Kansas City, MO)

I've had my baby (2005 Dodge Magnum RT) since day 1, 0 miles. Brand spankin' new. Paid off last summer. She's been pretty good to us besides a few things... Just looked on a forum here to find out how to fix the sunroof that isn't flushing right... also need to dig around to see how I can get the damn windshield washer fluid error to stop coming on, even when there's enough fluid. BTW, anyone ever experience all the lights and gages turning off while driving? It's done it a few times, but not in a while... it's scary not knowing how fast you are going on the highway. Eeeek. Most expensive fix was probably when my tie rods went out and some ball bearing stuff, at the time they were factory only... OH, and my emergency break doesn't work... heh.

Here's my most recent headache though:

Got code P0521 and bought replacement oil pressure sensor from dealership ($68 with tax). Replaced in rain. Fun. Fun. Started her up, no check engine light all day. Thought she was fixed. Next day, check engine light came on again. Ran codes and same one popped up. Called around and dealership said after you replace oil pressure sensor you have to get the computer flashed. Is this right? Resetting computer at dealership cost $85. Ugh. One thing I did notice is that the first time I ran the code before replacing the oil pressure sensor, it said something about oil viscosity. The second time I ran codes after replacing sensor, P0521 came up, but nothing about oil viscosity.

So, everyone who has replaced the oil pressure sensor... have you had to "flash" the computer afterwards to get the check engine light to come off?

Is there anyway the new sensor could be bad?

Is the dealership the only one who can reset the computer?

(I've also got a '92 RS Chevy Camaro (candy apple red w/black stripes T-top) in the garage. When she kept overheating, I got pissed and bought the Magnum and haven't touched her since.)

Welcome from south Alabama!! We were just talking bout codes on here... After a code pops up, and you fix whatever it is, it's my understanding that the code will stay through 3 drive cycles before it clears itself. I'm not exactly what a drive cycle is, rumor has it it's getting the engine up to temp and driving 50 to 100 miles..

I never flashed my computer but i had my battery disconnected during this repair (to reset my code once completed). I actually had to do it twice as the first OPS installed began to leak- jacked up threads... New one works great, no more codes.
And you're running 5w20 always ?

My daily commute to work is about 20 miles. So, I have to drive 50-100 miles non-stop 3 times for the thing to reset? Dang, that's a lot of gas.

Yes, the battery was disconnected during the OPS installation. The check engine light did go off afterwards, and I drove around to run errands etc. But it came back on the next morning with same error code. Called parts center and they said with OPS replacement you had to "flash" the computer for the check engine light to go off. I assume "flash" means reset.

There's about 125,000 miles on her now. We use the really expensive Mobil 1 extended performance oil when we change it. Yep, 5w20.

Check the sensor connection. The dealership is full of sh*t there's no need to flash the computer after changing the oil pressure sensor.
Pull fuse #11 in the under hood fuse block to reset the PCM.

i just changed mine this saturday, however i never got a cel, just the flashing oil light when the car was at normal operating temp. and idling, it would flash and ding then stay solid, soon as i drove , the light went off...one thing i read its important to do is clean out the connector with contact cleaner, busted oil sensors weep oil into the connector, giving the computer a false reading..

btw i didnt disconnect the battery or get a flash, it still flashed for a good day and a half then reset it self..all is well now..

Thanks Fireman2118! I pulled fuse #11 and ... no light! Well that saved me $85. Also, thanks DirtyPana for the link, before I took off to go home I did the sunroof fix in the parking lot in about 5 min.

bookeem, my oil light never came on, just the check engine light with code P0521. (I just run up to Advanced Auto Parts and they run the code for me for free.)

Dang, I should put some pics up or somethin. I'll be sure to check back here. Impressive site. I hate to break it to you guys... but I really really wanna get a new Camaro... Not sure how I can part with the Magnum though.
