And the repair manual was extremely important - I couldn't have done the job without it. The original multi-displacement system turned off opposite pairs of cylinders, allowing the engine to have three different configurations and displacements. They say they do these often. Since it is unlikely that 2 sensors would go bad at the same time, it is more likely an intake problem. It shifts beautifully and the gas mileage is back up 26-27 mpg in easy touring drives vs about 23-24 before. I know this isn't the correct forum, but exact same issues, hoping for some insight. If the code returns or there is a noticeable misfire, the first step is to fill the fuel tank.
Now I gotta figure out how much it'll cost to fix it. My guess is it might be the pre cat's or the plugs, I didn't get around to checking that yet. Time to check out your repair manual. Not fully convinced because the car drove soooo smooth I took it to a reputable indy who re-set the the error code and told me to complete a drive cycle of about 50 miles which if the code didn't return I was good to go get a smog test. I am very methodical and slow and it took me over 30 hours to do this job.
Basically this is telling you that the torque converter lock up feature is not working. You have to reach them from the rear using about 2+ ft of socket extension, and the bolts are external torx sockets. I have the same problem. First had Autozone run the codes and reset, they were back on same day. Car averaged just over 27 mpg while cruising at least 5 over all the speed limits. Hopefully it'll run for awhile now.
Basically this is telling you that the torque converter lock up feature is not working. If the condition is still present, the mechanic may begin to swap components on the system with another cylinder to determine which one is faulty. How serious is the P0313 code? Figure my next target would be the coils and plugs. Today I rec'd my Peake decoder and my Bentley manuals. A misfire can cause poor fuel consumption, higher emissions, and a rough-running engine, though usually it will continue to operate reliably. Just got back from a 3000 mile trip to Colorado.
The modular engine family uses gasoline and diesel engines that share common components and architecture. Otherwise, misdiagnosis can occur if parts are replaced before a thorough diagnosis is performed. Once the car cools down then the car has to clear 1 of 2 more codes before the code re-sets and off to the smog station. I plan on changing the plugs this weekend and getting to the pre cats hopefully at the same time. When I read the codes this time it had both P0171 and P0174. Hopefully I don't have to do this again but if I do it will be much easier.
Definitely make a thorough check before you dismiss it. With a fuel tank filled above the minimum level, a mechanic will continue to diagnose the concern by checking connections to the affected cylinder. I plan on changing the plugs this weekend and getting to the pre cats hopefully at the same time. How does a mechanic diagnose the P0313 code? With revisions and updates over the years it's unlikely that parts will simply interchange so knowing the specific engine type can be very helpful when sourcing parts. Have the plugs ever been changed? I hope that fixes it. Overall the car performed quite well over the ~800-mile round trip to the in-laws' house, and averaged about 28mpg. No other known issues since taking ownership at 32K.
You have to reach them from the rear using about 2+ ft of socket extension, and the bolts are external torx sockets. The yellow arrow is one of the two hose clamps that were the hardest part of the job. As suggested, the intake boot was decayed and torn open on the elbow leading into the idle control valve. There should be a slight vac, but if it's a very strong vac. I was wondering if anybody else had these codes and could lead me in the right direction to avoid the dealer. The solinoid was sending fluid the the clutch plates but the seal was letting the fluid pressure leak back.
The code is often associated with diagnostic codes P0300, P0301, P0302, P0303, P0304, P0305, and P0306. Here is some info that may help others: - The issue is the torque converter internal clutch seal failing. If I had the special tools needed I would repair myself Question is. My biggest issue was the starter removal. A tranny and torgue convertor will probably cost 3 grand. Man does it drive nice. If this problem is left without repair will it: 1.
Vacuum is created entirely separately by a belt-driven vacuum pump. This means that 2 O2 sensors are reporting too lean. At some point, since it is slipping the clutch material will be gone and it will be metal on metal. That's great that you were able to fix it! When I replaced them I put them right-side-up so I can get to them again when the replacement parts arrive. In some cases, fouled spark plugs in cold weather or worn spark plug electrodes can cause a misfire code. The signal is used as an input for various systems in the vehicle. With your engine running, try to slowly and slighty remove your oil cap.
I too recently got this code which prevented me from passing a smog test. Lots of work but worth it. For example, the inline-6 cylinder engines in the E34, E36, E39, E46, E53, Z3 and Z4 can all trace their origin to the M50 introduced in 1991. Second photo is the big-ass hole in the intake boot. You have to be careful not to strip the torx heads during removal or the game is over. Quick search and this thread is the first result.
