SOURCE: service engine soon & brake light stays on

the service engine light is prob due to the oxygen sensor being damaged, not replace or you having the catalytic converter taken off---just messing with you. start at auto zone and have then do a free code read then go from there. you should troubleshoot the low fluid level switch for your brake fluid. unplug it and see if the light goes off and if it doesn't jump the two terminals on the harness. oh the car will have to be running. Let me know MrRodneyLong@gmail.com

SOURCE: trouble code P0325 and P1444

Nissan code:
P1444 Canister Purge Volume Control Solenoid Valve

Generic OBD II code:
DTC Codes - P0300-P0399 – Ignition System or Misfire
P0325 Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor)

I hopes this helps you.
Replace or fix these two items should do the trick.
It's hard to diagnose a car over a computer.

SOURCE: service engine soon light came on and stays on

The warranty company was able to find a used transmission for $900 which was still under warranty and it will cost 11.5 hours for the install, plus shop supplies and diagnostic. Total cost about $2000. I drove the car for probably at least 10,000 miles and it was leaking a small amount of transmission fluid even after I fixed a seal (waste of money) before getting it fixed. I didn't see the fluid though on my garage floor though as there is something that would catch it.

Cadillac dealer stated this is a known problem with the clutch assembly and that there is a bulletin out on it. The reason the car stalls is due to the transmission not the engine. When the car is at a light or the like there is apparently too much strain from the tranny and it stalls the engine. My car didn't get that far, but after reading a bunch of stuff and looking up the codes it appears to be the case. Of course you could get lucky and the solenoid is just bad, probably not though due to the bulletin.

You can read the codes and clear the codes easy enough. If you don't know how there are many posts on the net.

SOURCE: service engine soon light stays on how do i turn this off?

you will need to take it in for a diagnosis scan. this Will scan for trouble codes that will direct you and your mechanic to the issue at hand. it will also tell you how to fix this issue as well. once this problem is fixed, the light will shut off.

In most cases, it a failed sensor of some sort. most auto zones will scan the ecm for free.

Service engine soon light


A service engine soon light that flashes generally results form an ignition problem with the engine. A service engine soon light that stays on constant results from an emission control system malfunction. A diagnostic scan from the local parts store can determine which emission system is faulty.

Airbag light and service soon light


You need to take this to a shop and have the airbag system repaired as that light is indicating a fault in the airbag deployment system. The service Engine soon light could be nothing more that a reminder to change the oil but is most likely an Oxygen sensor that needs replaced.

Service Engine soon light stays on but car runs


Probably needs an oil change (if it already hasn't had one) and the light reset. If that doesn't help, take it and have a code scanner hooked up to it, to find out why the light is on.
If there is an autozone or advanced auto near you, go there, and tell them you have an engine light on and need to read the code.
They usually don't charge, other places do.
