These cars do get to be a bit of a money pit after they get old but then again what car isn't. After driving it for a few miles and parked it the car wouldn't stay on after starting. The currently selected is for the Volvo makes. Deathjam4 answered 2 years ago This is most likely a cat issue. I reset the codes and it comes back about 2 days later. I'm in Florida so passing emissions isn't a problem.
The car doesn't drive any different when it throws the code, so I'm at a loss as to what it could be. I like my car running correctly in closed loop when it's supposed to, and by resetting readyness every week that doesn't happen. I never once got it in the winter. They didn't flag me for my aftermarket intake either, although this might be more dependent on which dealership you go to. Also the timing chain tensioner is leaking slightly which is pending a fix shortly. In addition, they should make sure that the direct ozone reduction catalyst is not under a manufacturer's warranty before beginning diagnosis. So I'm stuck and unhappy about it.
I've looked for the sensor alone, and haven't found anything. I can't find any info online as to what can be causing this or how to fix it. Came home, did a pressure test and couldn't find anything, I was stumped. I'm surprised there's not an easy fix for a stupid pointless sensor. At the time I really didn't worry about it as I only got the code about twice a summer. Bones, I've checked the gas cap too, but thats not it either.
Hello all, new to the forum. Contributing factors in direct ozone reduction catalyst converter failure may include incorrect fuel usage, excessive fuel being dumped into the exhaust system due to a faulty coolant temperature sensor, mass air flow sensor, manifold air pressure sensor, fuel pressure regulator, or fuel injection component, an ignition misfire, retarded spark timing, or oil contamination. It wasn't too difficult, but certainly wasn't easy either. Thanks, The other thread posted in the first post the guy did the same thing. I would replace the fuel filter as well as this can some times cause this issue as well if it is full of crap. I never once got it in the winter.
I reset the codes and it comes back about 2 days later. If the codes no longer match for example, due to tampering , a fault will be indicated. My other thoughts are, the sensor probably isn't reading stuff all the time. We are not responsible for any actions you take on your vehicle. I copied my post over from this thread to maybe combine information and solve this issue.
Technicians report that repeated direct ozone reduction catalyst failure occurs when other codes are present and left unattended for long periods of time. I would clear it and it would usually never come back. What causes the P2571 code? There'e enough room, you just have to space to radiator back with some washers. I pulled the code and it is P2570 Direct Ozone Reduction Catalyst Temperature Sensor Circuit High. He was able to just take everything back apart and put the sensor back where it was with no problems. I guess it could be. I reset the codes and it comes back about 2 days later.
I put my intercooler in back in 2011 and never had any issues, and it wasn't even spaced. It's only a 2 wire sensor, so it shouldn't really be overly difficult to trick it. Bad oxygen sensors are also a possibility but if this is the case an oxygen sensor code will usually accompany the direct ozone reduction catalyst temperature code. I've had to replace the radiator. Common Misdiagnosis The most common misdiagnosis is caused by not thoroughly investigating what led to direct ozone reduction catalyst failure. It's supposed to be a one use thing as a set with the radiator. I'm probably not out of the clear yet, but I'm hoping I am.
Luckily it was still under warranty. Common Causes The most common cause of this code is due to a faulty direct ozone reduction catalyst temperature sensor. How does a mechanic diagnose the P2571 code? The next most common misdiagnosis comes from oxygen sensor replacement. I have purchased the new rad, just haven't taken the time to get it installed yet. Like on the Unitronic website you'll see their intercooler is compatible with the Ozone sensor. Since the direct ozone reduction catalyst converter is not designed to wear out, its failure is normally associated with some contributing malfunction.
The car doesn't drive any different when it throws the code, so I'm at a loss as to what it could be. By just replacing a faulty direct ozone reduction catalyst temperature sensor and not fixing what caused the sensor to go bad in the first place means that the replacement sensor will more than likely go out again with the code reappearing. I can't find any info online as to what can be causing this or how to fix it. The mechanic should compare their findings to the manufacturer's specifications. I would clear it and it would usually never come back. Does anyone know what this is? The temperature sensor has an attachment for attaching the temperature sensor to the attachment point of the catalytic motor vehicle radiator, and includes an electrical identification unit for identifying the catalytic motor vehicle radiator.
I have one engine code P2570. Wouldn't the O2 sensors throw a code? Summer time rolled around this year and I got the code, cleared it and kept coming back every 2 weeks or so. Which makes no sense in my opinion. I hope someone can help shed light on a problem. Engine misfires are known to deteriorate the platinum element of the converter, as is excessively rich exhaust. This is a safeguard to ensure that all attempts at tampering will be detected. There's fairly frequent discussion of what you should consider.
