Hi all, My first post in car forum and it aint a good one. We all have those pesky SES (service engine soon ) lights on our cars & trucks, that is if
your vehicle is 97 or newer. My wife drives a 2003 Nissan Pathfinder. A great car, you can't kill em, trust me my wife has tried.
Here in N.C. our inspection is directly tied to registering our vehicles. If your car fails inspection, you do not get your registration & tags. If
your SES light is on the folks who you took it to for inspection want touch it, until the SES light is not on. Or problem is corrected.
So every year we go thru same thing, getting the car to pass inspection. Get the SES light out. I own a code scanner with erase ability. So I check
code, po1130 a (swirl valve sensor). So I correct that problem, simple fix of cleaning out the vacum lines in this system and lubricating the
mechanism on the intake. I erase the codes, drive the car 63 miles, no SES light.
So wife takes car for inspection. Wife calls says call failed because of exhaust leak at catalytic converter. I asked to speak to mechanic. He tells
me the car has bad CC and needs re-placing both sides and quotes a price of $1,200. I asked which code came up? He said there were no codes in
computer. I said then car passed inspection. He said no, it was a judgment call on his part.
I sais to my wife, leave, take the car to another place for inspection. She calls ma bout 20 minutes later and tells me the SES light just came on, 6
miles away from 1st inspection place. So that evening when she came home I checked the SES codes and low & behold I have two new codes, both dealing
with low oxygen at sensor bank one & two. I pull the car on the ramps to see this leak & bad CC. What I found was two loose oxygen sensors, I could
literally turn them with my hands. I feel the mechanic at inspection place did this so the SES light would come on, he knew she was going somewhere
else for inspect.
I tighten sensors, check the CC which arent really CC, this car has direct fit CC right off the exhaust manifold, the ones in question come to find
are called, Non California Compliant Catalytic Converter and they do zero for the performance of the car.
So this is what I have came to the conclusion of. SES lights are a good idea, except they now cause a monetary problem for a lot of folks come
inspection time. Most big mechanics shops want work, so they'll do as the arse hole did with my wifes car. No telling how much revenue this generates
for car shops. I found, take it to Jiffy Lube type place, they want a sale, normally they tell you your car needs wiper blades before it will pass, so
you purchase a $17 pair of wiper blades, they get a warm & fuzzy you get a warm & fuzzy and your car is legal.
Versus the $1,200 CC fix of two items that arent really CC. Summation. Be damn carefull who you get to inspect your car come inspection time. Get
comfortable with your car, learn about the sensors and their locations on vehicle and what they do. It saves time & money. Hope this helps some one
