#17 of 47 Nissan Sentra ECM O2 Sensor error code P057
Nov 02, 2007 (4:25 pm)
I have a 2002 Sentra which has a reoccurring error code P057 translates to Bank 2 Sensor 2 Heater element low. This was first diagnosed at around 40,000 miles. I replaced the O2 sensor and cleared the code seamed to be fixed. After about a month error code came back. So I replaced the O2 Sensor again. Again it lasted for about a month before the error code came back. At this point knowing that this would not affect performance I decided to forgo replacing it again. Now at 115,000 Miles I needed to get the emissions inspection done and returned to the dealer to have the error code checked out. They informed me that the cat and O2 Sensor needed to replace. So I decided to let them do it costing me over $1,300. Got the emissions inspection done 3 days later and that evening the error code reappeared. Returned to the dealer and now they tell me the ECM is defective. Which I suspected all along. So here I am good for 2 years on the inspection and still have the error code. Not sure what I will do in 2 years maybe trade it in or spend more money to replace the ECM. Any body know of a cheap ECM for a 2002 Sentra GXE 1.8L?
#18 of 47 2002 Sentra SE-R running rough sometimes
Nov 09, 2007 (9:45 am)
Car seems to run rough but only sometimes. After car is run for longer than 15 or 20 minutes seems to be fine. I've already replaced both oxygen sensors,car has 120,000 miles on it . Does anyone have an idea to what else might be wrong.After replacing both oxygen sensors seemed to be OK for approx. 2 weeks.Any help would be greatly appreciated......Thanks

Hi. I just recently purchased a "01" nissan sentra and it recently started actin up as in hesitating to stall. Eventually it got a lil worse and so on. My "check engine soon" light is on and itll stall as im at a red light or in "park" idling. if i quick throw it in "N" it wont hesitate to stall. I purchased an OBD decoder to clear the warnin signal. but this did not fix the problem. I did read the codes and only one come up sayng "O2 circuit sensors - bank 2 sensor 2- no activity". I take this that the sensor in that location is no good and not reading with the cars ECM. I plan to replace this sensor myself and save me some bux and headache from a mechaninc tryin to swindle me possibly. My question is.... Where are these O2 sensors the decoder is talking about? Where is Bank 1 & 2 - Sensor 1 & 2. To me it sounds like 4 sensors all together... 2 rows (banks). I found a location behind the radiator, in front of the engine by the dip stick with 4 what looks like spark plugs but i think they are sensors. 2 on top (right to left) 2 below them (right to left) are these the 2 banks and if so... does 1 & 2 run left to right, eg. sensor 1 (left) sensor 2 (right) ... bank 1 (top row) bank 2 (bottom row). Please help?

hey, save all those problem first, if you have the machine to check, see if one of ur cylender has mis fire going on. I had that problem after I had a big rebuild engin. and it was having the same problem like you said, and guess what thsoe dealer want to do? they want to reserve my engin and charge me again, but after I took to my friend's shop, then he found out is one of the cylender has mis fire problem, and when he check the spark plug, the head was bend. After he bend it back, the problem was gone.. So, have ur guy check if one of ur spark pulg has bended. that will need an experienced guy to see, because just by half inch, the engin can still stall.
That, my friend, save me another thousand dollar there.

thanks for the info. After reading up Alot was saying to check hoses for cracks or loose conections and probe plugs to see if any current would be flowin through, I discovered a hose connecting from throttle to engine where the clamp was in the wrong position and not keeping it secure. so i moved it up to where it should be and now it doesnt slide any more. I noticed that the car hesitates but doesnt stall. The "check engine soon came back on after clearing it . Im going to check for more simple lil things like that but Im thinking the sensor still needs to be replaced. Im still unsure of its location, at least not 100% that is, just an idea. still need a hint to where its/theyre located (see my original messege). Thanks for that tip. that will also be checked out if all else fails before i go to spend 100s maybe thousands on the lil stinker, hehe

I have similar O2 sensor issues, replacing them again, but after ecm change they will last about 80,000.
Here is a company I used http://www.ecudirect.com
You send them your ECM and they repair or replace the faulty parts and send it back to you or you can just buy a new one. I had mine repaired and they did a great job. Great prices and decent helpful staff. Give them a call and good luck

I have a 2002 Nissan Pathfinder and am having problems with the check engine light coming on. I just had the 02 sensor replaced and the light went off for a couple of days, then came back on. The mechanic said that a nissan mechanic would have to go in and re-set the computer to make the check engine light stay off. My brother has a 2001 Nisan Pathfinder that has the exact same problem and my sister has a 2002 Nissan pick up truck that has the same problem.
The mechanic said that the manufacturer should have done a re-call on these models because they were aware of the problem. Now I have to pay someone else to go in a re-set a computer on my car.
Is anyone else with a Nissan Pathfinder having this type of problem?

i sounds like a wireharness problem. theres definetely a wire cut some where and because of the car moving it short circuits.
#25 of 47 2001 Nissan Sentra GXE error code P0430
Mar 30, 2009 (3:40 pm)
Check engine light on, had it checked by service center. Was told the catalytic was bad. Had it replaced. Light was cleared but came on again. I bought an OBD ll tester. I got a P0430 code. "Catalyst efficiency below threshold (Bank 2). the vehicle has 4 sensors 2 top and 2 bottom. Bank 2, I am assuming, are the 2 located on the bottom. Can anyone help me to determine which sensor is the culprit? I need all the help I can get. Thanks
