Hi there guys. Sadly, my 96 Accord pop up it's first CEL. P0715; Input/Turbine speed sensor malfunction. Problems listed below.

I need more insight to this. I've read the threads and some of them say, your tranny is toast or just replace that sensor.

Today, like 67 degrees, went to school, reached 20 mph, and didn't shift. Then accelerating again, the shifting sounded like it was slipping. I will try to get a video later. Then the car was warmed up, it got little better, but still not too good of a shifting.

I need more insight on this. PLEASE! I have very little money, this is my car until i finish college. IF you can guide me through the process, it will be GREATLY GREATLY appreciated.

So sad right now..... =((

 

Honda issued a Service Bulletin 01-012 on May 15, 2001 for the issue. Honda's description for this is "The MIL comes on, and A/T DTC P0715 (problem in the mainshaft speed sensor circuit) is set." The repair procedures are to check the sensor circuit wiring. If the wiring is ok replace PCM and flush transmisison fluid completely, meaning all 12 quarts. If the flush and PCM does not repair the problem, the transmission will have to be replaced. Before you do anything I would take it to a Honda dealership to get it checked out before you dump a ton of money into it. It will not be covered under warranty so you will have to at least pay the 1 hour check out charge.

 

P0175 Front Bank (Bank 2) Fuel System Too Rich

Did you type it in correctly, transmission series codes start with P07xx ???

P0713 Open in ATF Temperature Sensor Circuit
P0715 NOT LISTED IN MY SOURCE

P0751 Shift Solenoid Valve A Stuck OFF

If it is a rich condition the first thing I would do is measure the voltage back to the computer from the MAP sensor, it needs to be extremely close to 1 volt DC at fully warmed up idle with no fans on or no accessories on either.

Which engine do you have in this thing? Get that MAP voltage please.

 

O sorry! P0715.

 

Just to make things a little more detailed...
D4 light is not blinking
Car is shifting little better when warm. Not much difference
My speedo is working just fine.
Transmission fluid doesn't smell burnt

Hope that helps narrow it down. Anyone please help!

I'll try to do the flush this weekend. and check the wiring.

EDIT DID THE SCS connector. The CEL did 7 longs. The D4 light blink 1 long and 5 short. Not sure if that's right. Maybe it was just 5 short blinks. Weird. I cross reference with the service manual. Faulty AT gear position switch.

 

In addition to my last 2 post, can you guys help me decode the D4 blinking lights? Is it 5 or 15? http://video.google.com/videoplay?do...83805502&hl=en

Thanks!

Also I've check the mainshaft sensor, and it was reading 511 ohms. The specified resistance.

 

Looks like code 5 to me...the first long blink always occurs, somewhat like a pause between codes.
However as you have OBD2 on your 96, why don't you pull the ashtray and get the REAL code, with a scan tool.
FWIW the pulse counters/sensors can get particulate build up on them and cause mis-counts of the shaft speeds.

 

I did get the real code with an OBD II scanner. P0715, as the first post says. I thought the SCS connector hook up would be more specific on what problem I have.

I did find the PDF for the one that Jas9848 suggested. I'm going to try to do some test, as my old high school autoshop teacher MAY have those readers to test the ECM. But I will take out the sensor and clean it and also flush the tranny.

Keeping hope... =((

 

I would recommend an OBDII Enhanced scanner, not sure if yours is enhanced or not. That means its the same info as a dealer scanner, not one that most of us guys buy here on these forums.

Thanks for the chart Yamada-san.

 

K guys so far, I have test the resistance of all the sensors and solenoid. And it's looking good. Which sucks, which doesn't mean its not the problem.

I took out the lock up solenoid just to be sure, and it's good, not clogged.

I am going to see if the solenoid works in the coming weekend. And I will see if the shift control solenoid is not clogged and working. Since it did pop up a code 5, which is the gear position switch, I am going to test that whole switch also. Wish me luck!

Any other suggestions? I really appreciate the help for those who have replied already.

EDIT!
Well after more hours of research, I think I know how to fix my problem. Bring it in to a Honda Dealer. *GASP* Yes, its true. The problem that I have is covered under emissions warranty. As you know, 96-97 Honda's Emission warranty is extended to 14 years! And if you look in the warranty manual, it's covered!

WHOO HOO!!!! I'm so happy! Thank-you God! =P

 

Brought it in to Honda dealer this morning. Check it out. They found the same code as I did. But all the sensors was good. Told me I needed a new tranny. Wanting to charge me around $3K to rebuild, I went back home, tranny failed in the middle of road. And that was that.

So I need a new tranny. or a rebuild. I live in Southern California and in need of a rebuild tranny. If you know any hook-ups or someone, please refer me. (So sad right now)

 

The Kid - how can i explain to teh honda dealer that this is covered under the emissions warranty ? It looks alike a transmission issue, I have the same problem on a Honda Civic 1997. All all sensors covered under this service bulletin ?

Is this service bulletin covered under warranty ?

'96-97 MIL Comes On With A/T DTC P0715 Transmission 01-012

 

Well, first of all, the warranty is extended to 14 years or 150,000 miles from the original date purchase of the car. http://img.photobucket.com/albums/v2...issionsext.jpg this one is from Acura, but shares the same stuff.

What I did was, I went to the dealer, I told him I had a CEL on and that I found the code and it should be covered by the extended emission warranty. They're going to charge you approx $100 to get it checked. If the problem was really something wrong with the sensors, that $100 is waived and everything is free. In my case, it wasn't the sensor and I lost $100.

What's wrong with the car? If you have the exact same problem as me with slipping and whinning from the tranny, I would replace the tranny cuz it's toast.

 

Thanks

When I am starting the car , it revvs up. I start at lower gear, it moves OK, and then when I move to higher gear, it runs smooth. When I start and try to move ( press gas) at normal gear, it makes a whoosh sound ( I guess it is revving up) and then I get a rocking noise as if the teeth of the gear is missing.

I also got the same code and took it to autozone and they said it is a sensor problem ( that is what the code read)

what is a CEL ? Why would a sensor failure be covered by the emissions warranty ? Is it a part of the emission system ? I am asking these as I have to relay the same info to the dealer

thanks

 

Well if you still have your warranty booklet (small thin book, same size as your owners manual) it will state what's covered and what is not. One of them is the sensor.

CEL is a Check engine light. Also may be called a MIL: Malfunction indicator light. Same light. Well, I guess they cover it because it affects the shifting time. If it slips, it goes to higher RPM and more fuel is used therefore causing more CO2 out of the tail pipe. IDK some stuff I made up. But it's covered. I'll try to find a warranty booklet for your 97 Civic soon, if i can find one.

One thing u could do is test the sensor. You can find procedures in the service manual.

 

Thanks.

My car has 132K miles on it, so I would doubt that anything is covered under warranty now, apart from the emissions. So, I need to understand how to explain that this problem can be related to the emissions. True that the CEL comes on time and again but right now it is reset. Is the history still in the computer ?

 

NOOO!!!! why'd you reset it? Without CEL you won't get anything repaired free from Honda.
Your warranty booklet will explain everything.

 

I did not reset the CEL. The clueless mechanic at the Mobil gas station did. I can wait for the next CEL to show up.

Also the car drives better in the last couple of days - with starting in low gear and then gearing up. Is it dangerous to drive like this ?

Thanks

 

My CEL came on again. Now I need to prepare myself to explain why it falls under that warranty / emissions service bulletin. Any help appreciated.

thanks

 

Did you find the warranty booklet yet? Then show them this letter. http://forums.slickdeals.net/attachm...9&d=1140553277

Sounds good?

 

Yes,I did find the warranty book, on page 14, it describes the emissions warranty and lists the sensors, it lists countershaft speed sensor - is it the same as input shaft speed sensor ( as shown in diag code P0715)

I cannot open the letter from slickdeals. Is it the service bulletin #98-081 ?

thanks

 

You have to right click and click save as or download. or open in a new window. Try again.

The document is for the Emissions extension warranty

 

thanks , it opened up in IE not Firefox

 

ok, here is what happened after I took the car to the dealer, they diagnosed a code P0715 as expected, input shaft sped sensor failure, performed diag tests for input ( mainshaft) shaft speed sensor, found internal resistance out of range, removed sensor frozen in transmission, filled transmission fluid.

and charged me $322

Now the question is whatever they replaced (mainshaft sensor) - is it covered under the emissions warranty ?

Now still I feel the rev up, but it is a little better, I do not get the gear tooth missing sound. They mentioned that trans has slight shift flare at times - what does it mean ?

thanks a bunch

 

I also found a TSB Number: 00-012 related to this problem, if there is a TSB, does that mean that it is recalled and will be fixed without cost to the consumer ?
