atc5 Posted May 29, 2009 Share Posted May 29, 2009 check your grounds...you just had the motor in and out...might explain the intermittent occurance. Link to comment Share on other sites More sharing options...
mccorry Posted May 29, 2009 Share Posted May 29, 2009 If I had to guess..... since I don't have anything here... I'd say a bad / failing crank position sensor.... Link to comment Share on other sites More sharing options...
suberman Posted June 30, 2009 Share Posted June 30, 2009 I have an 05 Leg GT, Man/Automatic. I'm running an 07 WRX engine in it. Everything has been perfect until yesterday, I got CEL P0700 (trans control system, MIL request) and P0725 (Engine speed input circuit). There was no difference in how the car drove or performed though. I read elsewhere that P0700 just means there is a MIL (malfunction indicator light) that needs to be read. I assume it is referring to the P0725?? But I wouldn't think P0725 is referring to a Crank Sensor since there are plenty of codes specific to the crank sensor. Seems like you'd get a "crank sensor" code if it was the crank sensor (p0335 and p0336). The "700 series" codes all have to do with the transmission. I cleared the codes and they haven't yet come back after going another 200 miles since then. Just to be sure though I think I might flush the tranny fluid and change the filter. I don't think that has ever been done yet so it couldn't hurt. Link to comment Share on other sites More sharing options...
red_suby Posted May 17, 2010 Share Posted May 17, 2010 Did you see get this code (P0725) again? Link to comment Share on other sites More sharing options...
suberman Posted May 17, 2010 Share Posted May 17, 2010 no, it never came back, at least not that I know of. It was a customer's car. Link to comment Share on other sites More sharing options...

BuiltLGT Posted August 1, 2012 Share Posted August 1, 2012 Anything on this ,I have this code now and car is shifting bad /slipping in 3/4/5...car does have excessive amount of tranny fluid it is high ass hell when hot and cold and I mean half way up the dipstick ..any thoughts ..I have an IPT Valvebody mod .

bmx045 Posted August 1, 2012 Share Posted August 1, 2012 BuiltLGT: you CANNOT overfill the transmission, drain the fluid until the level is at the top hole while hot idling on the dipstick. overfilling is detrimental to the 5eat. Link to comment Share on other sites More sharing options...
Scooby-ru Posted December 17, 2012 Share Posted December 17, 2012 I am getting p0700 on mine as well but I just replaced the engine. Didn't touch the tranny. Transmission shop owned by a friend told me to check all my connections but i find nothing. Gonna let him check it with a better than auto zone diag. Tool. Just that he's an hour away. And i hate to drive her that far with the mil on. Link to comment Share on other sites More sharing options...
Pmaltby Posted June 20, 2018 Share Posted June 20, 2018 I am getting p0700 on mine as well but I just replaced the engine. Didn't touch the tranny.

And i hate to drive her that far with the mil on. P0700 just let's you know the fault has to do with the driveline, it's a code used to refer people to the transmission section of the scan tool. Says something like "MIL on requested by AT" or something I have 2 codes related to p0700, they are p1706 and p0725 I'm pretty sure it's a wheel speed sensor but can anyone confirm? I work at a honda shop and sometimes they have the same issue. Link to comment Share on other sites More sharing options...
relative4 Posted June 20, 2018 Share Posted June 20, 2018 P0725 is typically caused by a bad cam or crank sensor preventing the ECU from sending a reliable engine speed signal to the TCU. I would address that first and see if fixing that also fixes the P1706. In general, it's helpful to know your year and model. Link to comment Share on other sites More sharing options...

mygtlegacy Posted August 6, 2018 Share Posted August 6, 2018 Bump! Just had this code showed on my car also today. P0725 and P0700. I recently installed an aftermarket grimmspeed uppipe on it 2 months ago and did a ohm resistor mod. Last week I heard some knocking sound on the engine and I really thought its something internal, but it seems its just the Timing Idler pulley(13033AA042). I drove the car almost 30 miles all the way to the shop and I noticed I started losing power and then finally the engine stalls and that's when the CEL came on and everything. Any advise? Thank you!

relative4 Posted August 6, 2018 Share Posted August 6, 2018 Typically the P0725 is the result of bad cam or crank sensors, but when driving with a bad timing tensioner, more worrisome things may have happened. Since it's almost to the shop, just have them look. Link to comment Share on other sites More sharing options...

mygtlegacy Posted August 18, 2018 Share Posted August 18, 2018 Bump! Finally had the chance to replace the TB Tensioner pulley, buy that wasn't the problem. The noise still present and it's idling rough. So definitely needs to be torn the engine and see what's going on unless you any of have better suggestions, or if there's any thread out there about my problem. I'm leaning towards engine rebuild or just direct swap. Link to comment Share on other sites More sharing options...
relative4 Posted August 18, 2018 Share Posted August 18, 2018 Did you replace the tensioner or just the tensioner pulley? Video? Link to comment Share on other sites More sharing options...
mygtlegacy Posted August 18, 2018 Share Posted August 18, 2018 Did you replace the tensioner or just the tensioner pulley? Video? It's the whole Timing belt Tensioner pulley assembly(hydro pin). Sorry but I got no videos. Link to comment Share on other sites More sharing options...
