Mazda 626 Fault Codes

13 posts in this topic

I had the codes on my 2000, Inline 4, Automatic, Mazda 626 checked two came up.

Anyone in here replaced the speed sensor? I need to replace it, Where is it located, inside or outside the Transmission? Where can purchase the speed sensor? Also I have a really rough idle, I mean rough, could the speed sensor be causing this? The other code was for a possible bad CAT Convertor, which of the two is cauing the rough idle, I figure the speed sensor has to do with the shifting characteristics, but what about the rough idle? Anyone here ever had an idle problem?

Anyone out there know where I can find some more information on this speed sensor issue? Any thoughts?

When was the last time you did a tune-up on the car? My 97 was running and idling rough, and I replaced plugs, wires, rotor, and dist. cap, and it fixed the problem tremendously.

According to my program, it's on top of the transaxle. Here is a diagram. It quotes: Measure resistance between both terminals. It should come out to 253-604 ohms. If not, replace it. Good luck...

JonJ, for what year and engine is your diagram for ? I also need to ckeck my P0715 input turbine speed sensor om ny 1997 V6 auto.

Twiggy-

I figured it out. V6's have the G4. Here is the diagram for yours. Same ohms as listed above... I just notced this is for the F4. The G4 is supposedly similar...

Update

In reference to JonJ picture above, here is my update. ( I know this is a 2.0l topic, but anyways...)

On my 1997 V6, I removed the air filter box, the battery and the battery tray to try accessing the turbine speed sensor. Only then, I visually located the sensor: it is in between the fuel filter and the engine/transmission mount. It can be visually seen from above, when the air filter box is removed. I was able to remove the sensor from there. No need to remove the battery and tray. I also unbolted and moved aside ( 2 small nuts) the cruise control unit for better access. I tested the TSS ( turbine speed sensor). The specs calls for 355 ohm impedance at 20 deg celsius. I measured 354 ohms: right on the nose!

I cleaned the contacts, and reinstalled the TSS. Dont know why the CEL was tripped with code P0715. Hope it will not come back.

Transaxle is just a term to describe a transmission that contains both the transmission and differential components etc. all in one case ;) This is common in Front engine - front drive or Rear Engine - Rear Drive applications... Its nice for the mfr because they put together the engine/clutch or TC/transaxle and then drop it into the car and slide in the halfshafts (no need to fuss with a diff and shaft). BUT, the term is used loosely - so if used improperly... no one really cares :P

Just for anyone still curious :P
