How long it took to relearn the pressures? I pulled the ECU today to take some readings and reburn the chip. When I reset everything the tire pressure monitor went into learn mode. I have driven it around for 20 miles and the unit still has not cleared. My wife is not so sure she likes me doing development work on her Reg. The books are worthless on this subject.
View 9 RepliesOkay, my newly delivered Treg came with Continentals, and are 225/55 R18s. The dealer had them all inflated to 45psi, however, the sticker in the door indicated that the fronts should be at 39psi and the rears at 45psi. Seems odd to me that the same size tire would have two different standard inflation levels, especially given that the car has the Air Suspension which would level out any unbalance in the ride height fron to rear that they may be trying to compensate for. What pressure are folks running front and rear?
View 5 RepliesThe temps drop enough this time of the year to necessitate adding air to the tires. Last week, got a low pressure warning, and pumped up all my tires to the desired PSI. On the road today, and decided to check to make sure they were all even. I noticed the right rear tire on the MFI icon was grey, and where the pressure is was a grey dash. Was driving for some time, and it never came back on. Then, when I exited and restarted, the right rear showed up, but now the left rear was gone. Then, after driving a few miles, all four showed up?? Never noticed this before. Could this be due to a low battery in the TPS, or some other weird gremlin.
View 1 RepliesI purchased a set of Scion FRS wheels. I assume these have TPMS sensors installed. I found the reset button under the dash and followed the directions in the manual. The light still hasn't gone off.
Is there a different method to get the TPMS sensors to relearn? Or did I make the wrong assumption that stock FRS wheels have sensors.
When the idle control valve is replaced does the ECU have to relearn the settings?
View 2 RepliesI've got the single zone a/c system -- On a hot day (here in VA a hot day is greater than 90 with high humitity), after the T has sat in the sun all day, it takes 10 or so minutes for the cabin to reach a comfortable temp, 69-70. By the way, I have the midnight blue with tan interior -- This could be a factor, you know, the dark car holds more heat scenerio.
I took it in last summer to ensure that the system was charged and operating at a normal level and I was told it was. A recent passenger questioned me as to why it took so long to cool off (and of course she mentioned that her 4runner cooled off way faster), I had no answer besides telling them to just be cool and the T will eventually will too.
I should have set a poll up, oh well, general comments are just as good. Side note -- Posting pictures, you do this through iServer? Or is the Insert Image icon just broken today?
I was curious as to how ambitious a project this would be and if special tools are needed.

2005 V8, 50k miles
Driving my '05 V8 around yesterday, I noticed a driveline bind like I get when making a long, accelerating left turn. Only this time, it was when I was going straight. It mostly happens when accelerating, right at a gear change. I find myself having to steer to the right to correct, then the bind, and the truck snaps to the left. I read up on the stepper motor issue on the FAQ's and it sounds like this could be a transfer case issue as well. I don't have a VAG-COM, so I can't scan for a code. I have checked all air pressures, and they're good. I have not noticed any abnormal tire wear, either.
I'm still getting a vibration/noise in the driver's foot well when feathering the throttle between 2500-3000 RPM, right at highway speeds, and it's enough to make you crazy. Dealership had the truck for over 30 days investigating this and blamed it on a bad tire. Two tires were replaced and put on the front. The noise is still there.
I'm also still getting what can best be described as a chain dragging noise coming out of the left side of the truck, apparently from the front end. I can hear it when driving with the windows down, up to about 35 mph, when wind noise masks it. The noise does not change at all with speed - it doesn't get louder, faster, or change pitch.
08 ES 350 with 53k miles. Started getting a low-tire indication last winter and air pressures all around were ok. Drove from Ohio to Florida in Feb and low-tire light went off. This fall, the light came back on, again the pressures were ok so the sensor must be sensitive to temp. What corrective action is suggested ?
View 5 RepliesI was driving doen the road and and all of a sudden I get a message to check the tires and the TPMS light was on. So I pulled over looked at the tires none looked flat. So I continued to a gas station to check the pressure. The pressures were fine, I had just installed my steel wheels and winter tires on Friday. What could have caused this and how do I reset it?
View 5 RepliesIn all fairness, this isn't for my SD, but there aren't really any forums for my '94 Villager and all A/C systems work pretty close to the same, so I thought I'd at least throw my question up here and see what comes of it. It's a bit of a hodge podge of manufacturers (Mercury, Nissan, Ford, Mitsubishi), but it's a Mercury, so technically a Ford.....ish.
My A/C crapped out last summer, so I finally got around to rebuilding it earlier this summer. I replaced absolutely everything except the rear expansion valves and the evaporators, which I flushed out with A/C flush and compressed air real good. Then I blew a line on a dirt road because I didn't get a line all the way clipped in. I got a bit paranoid about grit in the line, so I went ahead and replaced the line and dropped in a new dryer, sucked it all out good again, put a splash of POG oil in there, and filled it up with 134a.
According to the specs I could find, the capacity of my system is 52oz, or 4.3 of the standard 12oz cans. I always bleed the lines between cans to rid the lines of air and moisture as much as I can, so 4.5 cans usually gets about 52oz in the system. Anyways, it was 90 outside, so my readings should be 45-55 and 250-270. After adding 4.5 cans, and letting it run for a bit, my readings were still a bit low and my vent temp was only 60, so I went ahead and finished off the can. They were still reading low, so I sorta reluctantly hooked up another can and started filling. It sucked the whole can right up any my readings were 45 over 220 with vent temp at about 57. The low side is about on the low end of the acceptable range, but the high side still isn't quite up to the desired range and I don't want to stick another can in even though my readings indicate I'm not over-filled. I'm wondering if something's not right in there, or if maybe I'm just expecting too much from a 23 year old A/C design...?
Strolling into work today at 35-45 mph, it was a touch over 80 outside and my vent temp was a smudge over 40, so I guess that's not too bad. My radiator fans works fine, but they don't move a bunch of air. I usually drop an additional ~15 degrees when I'm on the move as opposed to sitting at idle.
Finally got the hpop in my 03 done, got it fired up and runs great. The longer crank times seem to be getting better, however I am a bit concerned when I really get into her I am seeing pressures of 3400 psi......seems high to me. I guess I don't know for sure what the IPR was reading, will have to check that. Truck runs great, nice and smooth, but I am afraid I am going to blow something.
What is normal and what is not? Is there a way this pump will dump excessive pressures if needed? Or is it just a matter of time before I blow an oring out somewhere? I'm not sure how much the pump is capable of putting out. At idle it's sitting right around 630 after warmed up, maybe a bit lower.
The light has been coming on for the last couple of weeks. I can reset the light by pushing the dash button. On a 700 mile trip last weekend, I probably reset it half a dozen times. The tires are all at 30 PSIg. Two tire gauges agree. I don't know how the system works. I don't think there is a sensor in each wheel like some later cars have. I suspect it works off of ABS sensors and wheel revolutions. The ABS light is not on, nor has it been.
The right rear tire has been replaced with one of the same size, but a different brand. This issue started a month after that. Can that tire have a different revolution length per rotation and cause this issue?
This is the 1.8, manual trans. Was involved in a moderate front collision. Car starts and runs, but not for long. What to check?
View 1 RepliesHow long should I expect my 2006 Prius (bought new in early 2007) battery to last? Right now I am at 52K miles after 3 years driving.
View 9 RepliesSo here is my delima. i currently own a prius and looking to replace my wife's vehicle. I thought maybe a EV would be great for a commuter. Problem is i have a long commute
45 miles to work.
i could probably charge at work all day(8am-5:30pm)
then leave from there to school and then home. which is 69-71 miles. <-- yikes.
Have a 2003 gmc truck 1500hd. When i come to a stop or at idle , my ac blows warm air out. At cursing speed it blows cold air.
View 5 RepliesI have a 2002 v8 lse with 92000. When i go to start it after it has been sitting for 20 minutes or more it cranks for a long tome before starting. When it does start it idles fine but has a strong fuel smell. There are no codes and no problems once it starts. However it starts up right away in cold weather. It seems like a flooding issue. The fuel pressure is within range but it does seem to bleed off quicker than most cars i work on when the engine is no longer running..
Unfortunately I don't have the specs on on fuel pressure runoff. I suspect the fuel pressure sensor/regulator. I don't believe it would be an injector due to the fact it never runs rough or misses once started and if it was the pump it wouldn't give off a fuel smell in the exhaust once started.
How long should 12V battery last in accessory mode?
View 19 RepliesMy AC went out the other day. My wife said it took about 10 to 20 mins to finally start working and blowing cold and the next day it would never ever kick in anymore. Vents are blowing but just a outside temp air, also the a/c light comes on and i hear slightly different idle when ac engaged, however i dont really hear anything happening with the compressor.
