    Where Is The Starter Relay?

    I just confirmed my starter was shot (probably the solenoid, not motor) by placing an alligator lead jmpr to the honking big 12v wire terminal on it and connecting to my meter. Put other lead to gnd to makes sure 12v at input to starter. Then I took the lead I had put to gnd and used another jumper with a pin inserted into the female control cable that goes to the flat blade connector terminal on starter and other end of that jumper to other meter lead. If the 12v direct wire from battery to starter has no op1ens you will see 12v on the meter. When you turn key to start, if the ignition and the transaxle switch closes properly, 12v is routed from battery to the female control line connector and you will see about 0v on the meter as the control line is now at 12v and the starter input has the battery 12v on it, so 2 12v leads on the meter l gives a delta of zero, meaning the starter is feed proper control signal and proper power input. See jpg mark up schematic below, its alot clearer. This is true for 2001 626 ATX, others I do'nt know. Also can't understand why the schematic shows an input from cruise control going into control line of the starter...anyone know. Don't mean to hi jack the thread. Quick test although a pain to get leads on from topside even after taking out complete air intake system. Bottom may be easier if you can get under. This is a good quick test to see if the ignition and transaxle switch work, I did it this way because I could not find the stinkin' transaxle switch. You can take the air intake tube, filter box and air intake tube to throttle body as one complete unit by loosening three nuts 2 bolts and loosen the hose strap at throttle body. Thanks for the other info too, I liked your transmission line quick fix, thats DIY engineering and thinking with available parts in your garage, bravo!

    Crankshaft Bolt Size

    Working on timing belt right now. Crankcase pulley bolt is 21 mm on 2001 626 2.0L FS Engine !

    On 98+ What Does The Camshaft Sensor Read

    Low Cost Scope. This may be late but someone wil see it eventually. http://www.amazon.com/1008C-Automotive-Diagnostic-Oscilloscope-Programmable/dp/B00BSR98KW/ref=sr_1_1?ie=UTF8&qid=1456189706&sr=8-1&keywords=automotive+oscilloscope about $88 bucks and has presets for screen and trigger setup for the various sensors in your car, which may or may not apply to the actual sensors in your car. I have a higher end scope I use for hardware design I do at home, I use it on my car as well.

    Replacement Parts

    In reply to question 3 on "if bolt taken off with 10mm socket, is that the size?" The bolt head socket size is not what describes a metric bolt. The size of a metric screw or bolt, is comprised of 3 specs all in units of mm. -diameter, -thread pitch -length, If you saw a spec saying in parts diagram calling out a M8 you need: M8-1.25 x 20 or M8 x1.25 x 20 M = Metric thread 8 = This is the Nominal diameter, in millimeters of thread width 1.25 = Pitch or the distance between thread centers, in millimeters 20 = Length, in millimeters of the bolt, threads only. This is for coarse and fine threads. If its coarse then the pitch may not be stated because its a standard, that is for an M8 coarse thread pitch is ALWAYS 1.25 (unless marked as fine thread and fine threads are standard values with respect to the diameter as well). You won't see 10 different thread pitches or types as with SAE NON METRIC threads and bolts/screws. Search for "metric thread size" and you'll get a zillion hits detailing the above and more. These specs are covered by ISO 261 and 262.
  5. Want to replace Torx screw as its a pain and worn out and will be removing Phillips screws for first time. Need to have replacement bolt/screws for these before I start job. Have seen members talk about replacing with hex or Allen heads but can't find size/length on mazda estores, here or elsewhere. Have 2001 2.0l 626 would appreciate if someone replaced these let me know. Thanks in advance. -Don
  6. I'm a newbie, posted this in "others 626" forum. Reposting. Sorry ! I just got got an OTC 3111 Pro scanner works fine in my 03 Impala, 04 Pacific, Cadillac's, Toyotas, Fords...just about everything, but....my '01 Mazda 626. It gets powered up so my ODB2 port has power and I also visually checked and measured the power and GND and ohmed GND and chassis GND pins to actual body and PCM GND . Scanner states starting to connect, then 30 seconds later reports "Link Error". I've tried Auto, Manual and just plain old ODBII settings a zillion times, won't work. After that I had my mechanic test to make sure my ODB port was okay, he read verified its working at this particular moment and pulled a P1506 off it. Anyway I called OTC tech support, knowing that my port works looking to work with them on solving this problem, I don't want to stretch this out but they instantly blamed my 626 port saying its broke even though its running with another scanner. Told me they use Pin 3 as a GND. (Really, dont think so). Started taunting me when I advised pin 3 is reserved, and would provide no more help. Want to say more about that conversation but won't. I've looked at the port to see what pins are hooked up, so I can see what protocol is used, didn't check with my mechanic at that time because I believed there would be just one protocol pin setup on the port. I see pins 2, 4, 5, 7, 10, 16. So 4 and 5 are chassis GND and GND, pins 2,10 would be for J1850 implying PWM which is usually Ford and some Mazda. Pin 7 is ISO 9141 or ISO14230-4 also used by Mazda. Pin 16 is power of course. I've also tried with my scanners batteries in, but it probably still sucks power from the port. So I thought perhaps the OTC scanner was confused by 2 protocols and choosing the wrong one even though and ELM 327 is smart enough to figure that out, what chip OTC uses I don't know. So I got a nifty ODB cable that 16 individual wires and I cut pin 7, hoping the J1850 PWM would work...nope, soldered pin 7 back and cut 2,10 hoping 9141 would work, nope, Haven't tried just a pin 2 but that's GM VPW. Anybody know what the protocol should be. I know Ford used the Mazda 626 so maybe thats why it had pins 2,10 hooked up and maybe Mazda uses pin 7. I found obdclearinghouse.com stated the protocol for 2001 626 2.0L is J1850 PWM, and on pinoutsgudie.com they said 2001 626 was ISO9141 although its just a very short collection of individual write in's. So if anyone knows or has connected to a 2001 or even 2002 or 2003 please let me know your scanners type, if anyone has an OTC 3111pro and it worked please let me know (doubtful on that). I plan on getting another scanner, I'll never get any help out of OTC, they have made that all to clear, again I'll just keep that conversation and opinion to my self. I did search before I asked, under "ODBIi Connectivity Problem" which was caused by a fuse, member 2016626 who has a 01 626 said he/she brought there's to an Autozone and they read the port so it seems it has worked on an '01. Can't do that here in CA. our gov't has made a law, because they know better then we do as always and will not allow auto stores to read your ODB port because that's dangerous. But selling you parts to rebuild your engine isn't...mhhhh haven't figured that out. Thanks much ladies and gentlemen....... now if this newbie can figure out how to delete that other post.

    Odbii Protocol For 2001 626 2.0L V4

    I just got got an OTC 3111 Pro scanner works fine in my 03 Impala, 04 Pacific, Cadillac's, Toyotas, Fords...just about everything, but....my '01 626.

It starts to connect and states that , then 30 seconds later reports "Link Error". I've tried Auto, Manual and just plain old ODBII settings a zillion times, won't work. I had my mechanic test to make sure my ODB port was okay, wife drove it down and he read verified its working at this particular moment and pulled a P1506 off it. Anyway I called OTC tech support, knowing that my port works looking to work with them on solving this problem, I don't want to stretch this out but they instantly blamed my 626 port saying its broke even though its running with another scanner.

Pin 16 is power of course. I've also tried with my units power on, it has batteries but it probably still sucks power from the port. So I thought perhaps the OTC scanner was confused by 2 protocols and choosing the wrong one even though and ELM 327 is smart enough to figure that out, what OTC uses I don't know.
