i just got a call from the dealer and they said i need an ecu, evap canister, and new O2 sensor to get the CEL to shut off. They want to charge me 409$ for labor and part for the evap canister, which is a 209$ part. 1200$ to replace the ECU and O2 sensor. i decided im gonna do it all myself. i have a 99 LS, stock motor. i need to know the exact ecu number i should look at buying. i looked in the marketplace but couldn't figure it out. any ideas on these problems, the prices, or anything else?

 

could i use this to replace the ecu? is this the correct one

come on guys i need some fast help here.

 

what's the actual trouble codes? dealers can say alot of shiets to make money.

 

What's the CEL code exactly ? That'll be a lot of help.

 

p1457 p0171 are the codes. this is exactly what the mechanics notes were:

two codes, p0171, fuel system lean. p1457, evap system leak. p1457 tested solonoids in evap system, heard all clicking. tested system for leaks, traced leak to evap canister. needs to be replaced. evidence of previous repair attempt. p0171 checked operation of primary O2 sensor, found sensor operating lazily. checked data list for O2 sensor input to ECM. found voltage values shown by ECM to be out of the operating range. often showing values in excess of 3.5 volts, operated engine while monitoring both O2 sensor voltage at the sensor and displayed voltage at the ECM and found values did not correspond. faulty ECM, needs to be replaced.

thats the entire note they left me on there. what do you make of it

 

bump, need analysis on this

 

if its the Evap you're worried about, can't that be taken care of by way of an OBD1 ECU? If so, you're looking at like $250 rather than the stupid amount of money they want.....dont do ANYTHING until you hear from people on this site....the last thing we need is more people getting ripped off....

 

yea they told me those amounts and i almost laughed at the guy. i've already bought the evap canister because i know the top was eaten away by battery acid. i got a new direct fit O2 sensor because i wired up the one thats on there and i want to make sure its correct. the ECU im waiting on until i get some more responses.


is this what im looking for an that would be a direct fit for the one i have now?

look here...i've spoken with 93turbo16 many times and bought a few ECUs from him....he'll help you out and take the guess work out of your purchase.....

Dealer BS
Thieves

 

ok i PM'ed him, thanks a lot. what is involved in switching the ecu. is it just take out the old one and plug in the new one? is it that simple?

 

change everything yourself....they really easy to do and you should do the ECU last because it very rare for an ECU to cause a CEL but it can happen(especially with a dealer).

 

yea im gonna do that last i think. does a chipped ecu do anything for power or HP on an otherwise stock setup? forgive my ignorance on this

i also work at a dealership and ASE certified with most of my work doing drivability complaints. it sounds like a legit diagnosis. according to the repair order, it sounds like the tech took the correct steps in diagnosing both fault codes. if you are familiar with oem diagnositic flow charts they are very similar (OBDII) with emissions and o2 sensor DTC's. if i were to have the same codes i would probably take the same steps diagnosing the problems. now what the tech wrote down compared to what he did is a totally different story. but according to the tech's story, it makes sense. if you doubt the technicians diagnosis you should attempt your own.

 

i have this po171 code as well... changed the primary o2 sensor checked for vacuum leaks. fuel pressure is ok.. i'm stumped as well

if your concerned about the canister, i got one to sell i removed it from my car, and i didnt think a ecu gave itself a code, if it was bad. Hows that possible??? look at your ecu numbers and match it with the same, its that simple if for some reason it is bad which i doubt

very true i hate when dumb ***** talk **** about dealers! those ***** should fix their own car themselves.

 

i took the part out myself and put it back in, in 15 minutes. they wanted 200$ for doing exactly what i did. no. i am doing it myself because i WAS getting ripped off. at the service counter they said the evap canister was 209$. at the parts counter 15 feet away, i bought it for 174$. i was getting ripped off. thats why im doing it all myself now

 

hows the car drive now with the evap re done ?

Dealer BS Never fair prices, ever.

 

the evap canister isnt done yet i have to pick it up from them on monday. although after the dealer reset the ecu the CEL hasnt come back on yet. its been about 85 miles or so. so whatever the problem is, it has to be a very small one.

ok most people dont realize Acura has put them selves away from honda and way up into the luxury line. thats why most people with older acura's think its unfair pricing for labor and well most of the parts. Most of the integra's parts are still made in japan thus more expensive parts and our labor rate down here is in FL is like $95/hr. it used to be 80$. I think i happen to be a fair person when quoting labor time's for cars like ours stock modded etc. i think suzawa94 agrees with me on that. to the OP if your going to sit here and bitch about the dealer so much why did you even go there in the first place. to find out codes that you could of pulled yourself and looked up on here to save you time andride to the dealer?

 

when you cel light turns on does it put your car into limp mode.. when my cel 45/p0171 turns on the car still drives fine. ie ( normal redline vtec xover etc) just runs pig rich due to the ecu trying to compensate.
