2004 Acura MDX, check engine light came on. Got code checked: P0741, supposed to be switch or torque converter. My mechanic won't do transmission work, so took to dealer. They drained fluid, no metal shavings. Now they want to replace transmission, said it has internal damage. It wasn't running badly, a little slippage here and there. Don't think it really needs replaced.
View 7 RepliesI bought a 2007 Toyota Matrix new, and it now has 41,800-something miles on it. At 38K miles the check engine light came on while I was on vacation out of state. The nearest Toyota dealer checked it out, told me the check engine light code was P0741 - problem with the torque converter - but they didn't see any obvious problem and the car drove fine for them and for me. They turned the light off but it went back on before very long. The car has now been to 2 different Toyota dealerships near my home because the check engine light keeps turning on. They also report seeing the same code, also seeing nothing obviously amiss,and tell me I need my transmission replaced. This seems preposterous to me for such a low mileage Toyota.
In December, when the check engine light went on again, I discovered it would turn off if I filled the car with gas. It still comes back on; if I either fill the car with gas, or simply open and close the gas cap, the check engine light will turn off after 3 - 4 trips with the car. What does the gas cap have to do with the torque converter?
What's really weird is that the light always comes on under the same conditions. Most of my driving is short trips, a couple of miles in town at around 30 mph. The light never comes on during "town" driving. My highway driving consists of trips of about 1 hour; parking for an hour or two; then returning home -- again, about an hour's drive. The check engine light always comes on when I'm doing highway driving on the trip home. I've clocked the mileage for the last 3 times the light came on. It came on after highway driving a total of 48, 51, and 48 miles, respectively.
I have a new to me 07 MDX with 82k miles. Exactly at 1 mile over the 30day/1200 mile used car warranty the Check Engine Light illuminated along. The NAV screen showed an emissions code P0401. I really don't notice any symptoms in running at all. Anyway a few drives (on/off) and it turns off for four days. It happened again with same code. Again few drives it went off. It seems to happen when driving easy. It gets great MPG in mixed driving on average (20MPG) which is far better than its rating. Should I wait till it stays on steady before I address this?
View 3 RepliesI driving 2011 Sonata. Check engine light was ON while driving, which are fault P0741, TORQUE CON CLUTH ABNORMAL. The light sometimes ON, and sometime will OFF while driving, is it any problem?
View 5 RepliesI have had a check engine light go on and off with P0700 and P0741 but since the flush day 3 it hasnt come back on and it was chucking with rpm doing small jumps... but now it does it in the mornings after sitting all night after a few chucks its fine for the rest of the day til the next day no check engine light so far, but transmission flush has worked a lot not as bad as before the flush.. So what else could be causing it? Its a 2006 hyundai santa fe with 274,000 kms.
View 24 RepliesI have Acura 1996 3.2 and its a great car but about 2 months ago the Check engine light is on and when i try to accelerate on highway or just on high speed it wont go in the next gear at the moment but when I am gonna press the pedal harder suddenly it will accelerate in a second. Also when I am standing on the traffic light the dashboard starts shaking and its a feeling like a car is going to turn off. Its an automatic. And this happens more frequently when the tank is full.
View 8 RepliesThe check engine light on my 1997 Integra (LS, 119K miles) has come on for the second time. Including background below.
Incident #1: Carin mid-June, the car sputtered or shook a bit when starting and the check engine light came on.The car had been sitting in the garage only about a day. Codes were P0303 (Cyl 3), 0304 (Cyl 4), P1399 (multiple misfire), P1300 (random Cyl misfiring). The p0303 code set at 1600 rpm & at 75F degrees. Misfire code set during warm-up. The shop performed block test (came negative). Compression tests show 1, 2, 4 at 200 psi & 3 at 190 psi. The shop replaced spark plugs & inspected plug wires & connectors as well. Valve clearance adjustments also were done. The shop cleared the engine light code.
Incident #2: Last week (early Aug), the car again sputtered & shook when trying to start (had been sitting in the garage for about 2.5 days). Showed signs of low or dead battery but started after cranking a few times. The check engine light came on again. Codes (checked at home using the jump method) indicate Cyl 1 & 3 misfire.
Will be taking to the shop for the diagnosis again but wondering if it is battery or ignition related; shop doesn't suspect the battery, however, I do sense that the battery 'feels' weak esp. when starting. New battery put in May. What could be going on?
08 RX350 with ~100K miles. Two weeks ago the Check Engine/TRAC light were on, VSC light blinks, so I tightened the gas cap, and pull the negative and cleared the code. Hoping this is just a gas cap issue.
2 weeks later all those lights are back again, so my mechanic pulled the code and came up with P0128. He told me it should be the problem with the Coolant Temperature Sensor. The water pump, thermostat was replaced last year and coolant level is OK. No issue with coolant temperature and the car drives like normal. My mechanic cleared the code and told me to drive it again until the lights come back and he will pull the code again.

My 2004 Lexus RX 330 with 116,000 miles has a check engine light on. The code was P2198, the problem: Bank2 Sensor1. I replaced the O2 sensor myself, easy, at $180. I erased the code and the check engine was back on the next day. Not sure what to do next.
View 9 RepliesI have a Mazda Tribute 2006 2.3. The O/D light would come on, drove it to a friends to scan the check engine light code, and the car almost made it there and then wouldn't remove in reverse, forward, or anything. Turn it off then start it up still wouldn't, then turned it off let it cool and it worked again for a little while.
The code was P0741, just the one code. Took it to a shop to have further tests, they seemed to think it was the clutch was worn and when the fluid heated it lost friction.
Pulled the transmission and thought why not do a Transmission rebuild? I have never done one but there was an awesome video on youtube of the guy doing it so I figured it couldn't be too hard and was just going to try my first rebuild.
According to the guy in the video you always need all new bushing, and we will get a rebuild kit with new clutch packs and the other stuff that comes with those, and sounds like it's a good idea to replace the torque converter.
The car is only at 85K and it looks like the transmission was rebuilt once before he got it at 80K. Maybe a bad rebuild?
Here are some pictures .....
The Input Sprag bearing was shredded and the bushing looks terrible. Can I just replace the bearing and the bushing? Is there any other damage I should be looking for because of this?
The forward planet you can so some eaten metal on the edge and 2 gears spin super smooth and the other 2 you have to push pretty hard to get them to turn. So new forward planet?
The shell's corners look a little rounded I wasn't sure how much was to much, can you tell from the picture if it looks like too much?

Finally got my first check engine light at 108k miles. Pulled my codes with an OBD reader from Oreilley auto parts.
P1117 is Coolant temperature sensor circuit, low for coolant heat storage system.
Coolant heat storage tank outlet temperature sensor.
Short in temperature sensor circuit
ECM
I just wanted to make sure I had the right piece before I buy it. I did check the levels of my coolant and they are perfect, so I'm sure the sensor must be bad. I believe it'll just be a water temp sensor. I just want to make sure it's this, and not some random sensor I'm missing.
we have a Prius from 2004.
We have had problems with the starter battery. This is because the car is so rarely driven. So to fix this I have charged the battery several times. But have not disconnected the battery cables before. I don't know if thats the reason why we have problems though. But you can suspect that.
One morning when we should drive the car we saw that the "check engine light" came up on the dashboard. And other warnings also.
I bought an OBD scanner and hooked it up. P3030..
So I took the hybrid battery out of the car and cleaned all poles and connections. I measured each battery cell to approx 7,6 V.
I also bought a new starter battery. Now, I have put all together again. But P3030 is still the case.
Is it possible to measure the voltages from the busbar module by measure on the contact to the ECU? I have tried that but don't get stable results. The voltages goes up and down all time..
My last hope is that a wire between battery busbar and ECU is broken. But I couldn't recognize that when I had the battery out of the car.
My check engine light came on with a p1116 on my 2008 with 138k. I replaced the sensor, but the p1116 came back. How to fix. I'm going to replace the coolant today, I read somewhere there might be a clog.
View 1 RepliesI had a check engine light and code 0420, which after researching I decided to replace the cat with an aftermarket - Magnaflow 99205HM. Spent some time driving around today and the light is back on!
View 1 RepliesI was driving when the engine light came on. I always carry my OBD II reader in case this happens. Upon reading the code it gave a reading of PA080. Since I have a spare battery at home and have fixed 3 others for friends and family I was not to worried.
I arrived home and took out the battery to measure the voltages. To my surprise all voltages were good. I figure maybe it was corrosion so i tool the module bus harnesses and cleaned both the copper pieces and screws. After reinstalling all i took it out for a drive and after 20 minutes the check engine light came on. Bummer!
Went back home and disconnected the original HV battery and installed the spare HV battery and took the vehicle for a ride. All seemed good when the engine light came on again after 20 min. Removed that battery and all voltages were also good.
Troubleshooting began first by checking the 12V battery with an ohmmeter and it read 12.4 volts. Thinking this was good I jumped at checking the HV
battery including switching the CPU to no avail. In the process I left the HV battery disconnected which gave me codes indicating loss of communication with CPU scaring me even more.
Finally decided to take a break and look around on here and google when I found a better way to test for a week 12V battery. This test required me to let the car sit, turn lights on and press power button twice. If I got a red triangle and message indicating that the transmission sensor was in an abnormal state a weak 12v battery was to blame. So i went put to the car and tried it to my surprise I got the red triangle with transmission message.
So I went to OReilly and got a 12V battery for $170. Came home installed it and took Prius out for a drive. After 30 minutes no Check Engine Light. So far all good. I drove it to work and back home without an issue. This car has 141k miles and 12V battery was approx 5 years old.
I got an 2009 toyota prius I was driving home one day and car shut off and check engine light came on after 10 mins of the car being off I try to turn it on, it started with the check engine light still on main battery light came off, I ran to AutoZone and got my car scan for codes and P0121 was my code tps my car has 120k miles what should I do clean the throttle body? Replace the sensor? How would I test the sensor if it's bad?
View 4 RepliesI took a one owner 2009 with 100,00 miles for a pre-inspection today. All came back in fairly good shape however the mechanic ( an independent shop ) found this error code P1455. I took the car back to the dealer & said I was interested in the car if they looked into whether the gas tank would need to be replaced. The parts manager gave my husband and I a long speech about how they checked the car before it was traded in and never found this code. He explained that the code has to appear twice for the " check engine light " to come on. He told us he would take the car for a test drive himself & put it thru another diagnostic test to see if he could get another error reading. He will be getting back to us tomorrow. The dealer also said we could discuss in writing a timeline for them to repair it if the check engine light come on & ultimately a repair is needed.
View 3 RepliesI'm guessing that I need to repair or replace the HV battery. But I'm not sure.
Today I drove for about 20 minutes with no issue. 10 minutes later, I got back in the car to drive again. This time, after about 20 seconds into the drive, a string of dash lights came on; Red triangle, VSC, Check engine.
The VSC light went away. But the red triangle and check engine light are still on. So, I had the trouble codes pulled by a mechanic, and the code P0A80 was returned along with a statement reading 'replace hybrid battery'.
Should I take this at face value? Or look for something else first?
2007 Prius - 150,000 miles
I have a 2005 with 206,000 miles and the check engine light came on. The code reads "pedal position" but local mechanics are not knowledgeable to deal with electronics. The check engine light has been sporadic off and on so is this serious?
View 5 RepliesI just got this very nice Elantra 04 with 64k on it. Yesterday suddenly I got the check engine light on. Today I went to Auto zone and they have checked my car and it showed code P2626. But there are more than a few suggestions about what could be. I don't know what to do. See the attachment below.
View 1 RepliesCheck engine light was on solid - so I hooked up a code reader to the OBD2. Went ahead and cleared code -- hasn't come back yet, but wanted to see what it might be indicating if it comes back on.
