I had my regular Subaru mechanic check the code and it was 0420. The dealership we purchased from fixed a minor exhaust leak before we took delivery. The vss1 goes through one of the two big plugs on the tranny. Should I switch to 89 octane? I am in New Zealand, and have a Dec 2006 Tribeca 3. If the problem continues even after sensor replacement, the issue is either the circuit wiring or the transmission control module. If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes.
At about 157K, I remember hearing a rattle from the bottom of the motor. Today they did not do the test for the emissions only read the code which I was unaware that reading the code and the test you mentioned were 2 different things of until reading your site. Unlike the cheaper Haynes and Chilton manuals that cover multiple year models, leaving the exact information you need to fix your car, these professional manuals cover your exact year, make, model. Other makes are experiencing the exact same issue Subaru Is not alone in this and its he price of clean air. I reset the code and let the wife drive the car normal driving for a week and it will not throw the code. In order for the conversion to work efficiently it needs lots of oxygen. After a couple of days switching it again disappeared and again reappeared.
The catalytic converter would be the last resort but, because of the age of the vehicle, it may be at the end of its life. Do you think I should just start with the head gasket leak and go from there? If it justs flashes in half second bursts continually you have no codes. I may drive the car around a bit at a higher rpm, as was mentioned above. I guess my lesson I learned was to make sure the car is smogged before I buy it: Well, unfortunately the car died before I could even look at it: On the way home from work it had some hesitation that at first I thought was caused by me not shifting correctly however a few miles down the freeway while going 75 the car started losing power and surging. My son is an auto tech, and scanned to find the dreaded P0240 code.
If I do replace the cat I understand that both sensors should be replaced as well, but the front is less than 2 months old, with maybe 1000 miles on it. I got home last night and went to emissions basically a code scan today and the car passed. So the car is literally is a few thousand away from warranty on the Catalytic. In the mean time I would look at buying this so you can periodically scan it your self for codes to make sure nothing has changed. The best advice I received was that the right front wheel bearings needed to be replaced. Did the techs come up with a solid fault? This being an obviously dangerous and scary situation, my short term solution was to cut the wire going to the sensor until I could replace it.
Now, I own and run a good shop that cares about our customers, If you go to a Dealer it will be higher, if you go to a general repair shop it may be higher still and not correct, if you find a version of my shop near you, than you should expect to pay close to what we charge if not it will be different. We had the headgasket done a month before the code appeared. If either circuit is open, it will need to be replaced. The Cerium acts like a sponge and soaks up the oxygen when the system is lean and releases the oxygen when the mixture is rich. After warm up I ran it while parked at about 3000 rpm. If the P0720 code does not return, it likely is an intermittent issue, rather than a problem with the output speed sensor. Keri Hi Keri, The Cat Code post head gasket repair is something that does sometimes come up, we try and advise customers to try and increase exhaust temperature a bit, post repairs to try and avoid this if at all possible.
That was early June of 2016. It looks like two bolts and it will pop right off, but does it plug into the tranny harness before the big multi plug, or do I need to cut wires and solder in another vss1 when I replace it? I then had it towed to a local transmission shop where it is awaiting a new driveshaft from Subaru. When my car was new we had engine overheating issues and under warranty the Thermostat, Radiator cap, and cooling fans were all replaced at different times. Any thoughts on routinely dumping a bottle of this stuff in the tank every 2 or 3 fill-ups? Dealer checked and said that yes, it might need a new converter. My biggest confusion is which cat conv is the problem.
What diagnosis switch are they refering to? Any ideas, did I do it wrong? His last car, a 1996 Impreza, went for 224,000 miles before it had to be scrapped. A reputable technician will start by examining the freeze frame data from the trouble code scanner, which will give them information about the code, and will allow them to search for additional trouble codes that have been detected. I objected by saying that it could be running rich for two reasons: -cat is not doing its job -engine is not doing its job. Any info appreciated and sorry for the lame attempt with the other post about this. Regards, David Hi David, The place to start is the Reflash. If it hasn't been used before or was returned to its original position , B82 and the 'diagnosis terminals' will be taped to the harness.
YourMechanic is an excellent option for your because we come to your home or office. I bought it used so, I have no reference to what may or may not have gone on with for the previous owner. The car is running fine, no problems. As far as what the service writer told you there are some dealers that will scan a code and give you an estimate without doing any real type of diagnosis. What do you think is causing these sounds from the front end? Current and historic fault codes will be displayed as illustrated in the figure below.
The vehicle may also experience a decrease in. The vss1 goes through one of the two big plugs on the tranny. So I had both front bearings replaced. All steps should be followed in order to make sure that the inspection and repair is both thorough and efficient. Failure to follow the trouble code diagnosis protocol can result in the output speed sensor being erroneously replaced when a much simpler issue was the problem.
Howdy Justin,Thanks in advance for reading and advice. If its over 80,000 miles than you should budget for a Catalytic converter Replacement in the Future. After dumping money into these repairs, last thing I want to find is that I now need more expensive repairs. Thanks for any insights you can offer! Its possible after some spirited driving the Catalyst function could improve and light goes out, but under stand its a warning of things to come. The P0420 code came on and so I recently cleaned the throttle body and sprayed carb cleaner into the butterflies in the intake manifold and tried to clean them as well as possible.
