Ask the Toyota mechanic!

Thanks for the help and advice Ruggy, I didn't pull them out I just checked coil packs which the boots were fine it was just the hard plastic bodies that had full length cracks down them. Do I need to replace the plugs when I replace the coils as well? If I cant get this code to go away am I going to hurt my engine if I keep driving it with a lean code?

 

My only concern with the coils is that they could cause the surging you were feeling. Half throttle in humid weather can cause this. I don't think its responsible for the lean code. Pulling the spark plugs could help identify which cylinder or cylinders could be causing the issue. The spark plug will appear very white and clean compared to the others. If your absolutley sure that the lean isn't from a intake manifold leak then look at the injectors. The plugs may be able to tell you which injector or injectors are running lean. When you have them out replace them. No worth putting used plugs back in.

The problem with leaving it run lean is eventually it will probably turn to a misfire. Lean conditions cause higher heat in the cylinder which can lead to detonation.

 

Ok just drove the truck into town and now coming up the hill to my house it started surging every time I gave it 25% throttle. It has never done this before on this particular hill. Starting to think I might have low fuel pressure.

 

Toyota fuel pumps are very reliable. If the pump was the problem it wouldn't care if it was on a hill. If you can't replicate the surge on flat ground then it may be water in the fuel tank. Water settle in the bottom of the tank and when you get the truck off level the pump can pick up the water causing the surge. Run some isopropyl in the tank and see if it improves.

 

Why does my transmission only shift to S only. shifter cable is working normally, but car only goes into gear in S(1st gear). The gauges only light up when in S, and do not light up for the rest p,r,n,d,2, nothing s only lights up. it will not go in reverse.

 

Had a shop try to install the westcott lift on my brand new TRD PRO. They beat the living heck out of the shocks. Anything to worry about here??? There might be a small hairline fracture. Hard to tell. I hope Its just cosmetic.

 

I've put in a lot of Tundra struts and I've never had to do that. Structurally it's probably OK but I won't be happy with it.

 

Go in and raise a fuss. Tell them you don't feel right about the damage and you simply dont trust it. The weight of the truck goes through the struts and it could be a safety issue if it fails.

 

Yeah the whole experience with this shop was a mess. I will probably get some new eyes on it. I can live with cosmetic stuff but they were beat up so bad I just dont want one to fail on me. Only 600 miles on them. Major bummer.

 

If the shock is cracked, I would expect them to replace the shock.

You can use a dye penetrant test kit to confirm the existence of a hairline crack. Unfortunately, complete dye penetrant test kits will cost around $70. If you already have some brake cleaner, you can probably buy individual cans of penetrant and developer, and skip the cleaner, for about $50.

The way it works is you spray on the red dye penetrant which flows down into any hairline cracks. You clean the part with the cleaner, removing all traces of penetrant from the part surface. Then you spray on the developer, which is a white powder. If there's a hairline crack, the penetrant that remains in the cracks will bleed out onto the developer, leaving a trace that's easily visible.

Hi,

Got a tpms dash light flashing after new tires were installed. The error code is this. Any suggestions before i take it back to the shop that did the tire install. Thank You !
C2144 - Transmitter ID 4 Error

 

Oops, looks like they may have broke the sensor. How did you retrieve the code? Do you have Techstream?

 

DAMN!! I installed mine and did not put a mark on it. Those shocks came out and went in easily.

 

Yes i do have TS. Is there a way to see if it's broken. I just removed the valve stim cap to check the little pin, see if they are bent and tugged on each stem. All look ok and were tight, no wiggle.

 

No way you can tell unless you break the tire down. The sensor will break off the valve stem so everything looks fine from the outside.

Open up techstream and go to the TPMS module. Choose the data stream. You should be able to see four sensor with their ID numbers and the tire pressure.

 

All the tire pressures and ID's are there. Is the code still there? Clear it if it is and see if it comes back

 

Yes, it's there off to the right on that pic.

I will try and clear it and see if it comes back

 

Yep, cleared it and went for a drive and about 5 minutes same code on same tpms id 4.

 

Let try something. Connect techstream and go back to the data list. Air down one tire at a time and watch the data list and see if they all react.

 

Ok - I will give that a try tomorrow and report findings. My laptop is about to die. Need to plug it in for a bit.

Thanks for the help. I really appreciate it.

 

NP. I'm kind of curious which of the sensor is not going to respond. When you figure out which wheel doesn't respond you could take the wheel off and roll it around and see if you can hear the broken sensor in the tire.

 

Limited slip differential

Hi,

My name is John and I drive a 2007 Tundra with a limited slip differential (not sure if this is an option or standard). So my question is regarding a deceleration type feeling (like when you are going down hill in 2nd gear, but not quite that much) that I get while the LSD is on. I thought it was normal but when I turned it off I feel like the truck rolls more freely on straightaways and down hill.

Is this normal or would this maybe be signaling something. No noises or anything like that so far. And the slow down feeling is not strong at all just a slight, more controlled feel, which I had thought has to do nothing with limited slip but I know very little.

Thank you

 

Hello John

The LSD on you truck uses the braking system to control wheel slip by applying brakes on the rear wheel that doesn't have traction. The differential is open and locking one side transfers the power to the opposite side thought the spider gears. I don't believe it comes into play in deceleration conditions and it is only active at slower speeds. Forgive me but I can't recall the exact speed.

It's probably the 2nd gear deceleration that your feeling but not sure why your LSD button would make it feel different.

 

Ohh

 

Well - the laptop took a dump on me the other night, guess it was more than just a low battery. Good thing I work in the I.T. field. Getting fixed today..

Quick question - The tires were just put on the wife RAV4 this past weekend and we never had any issues with the sensors prior.
How often do those TPMS sensors go bad? Ive never experienced one being bad and we've had Toyota's for 10 years now.

I know thats a very open ended question, just curious. The car is going back to the shop Friday evening for drop off, with a copy of the TS error I posted.

Be interesting on how they respond.

 

The battery in the tpms lasts a very long time. The dead ones that I have change out were more than five years old.

I suspect the sensor broken because your issue didnt start happening until after the tires were installed.

 

Thats what im thinking as well. Ive been going to the same shop for a long time, so im hoping this gets resolved in my favor.

I'll will report back... Thanks. I appreciate all your assistance.

 

Hi I went to the dealership today to do a transmission fluid change and they did the multiple point inspection and the only thing they said in the comments was that the “Rims too small for vehicle and causing wheel weights to rub against rotors” in those exact words. My tires are slightly oversized so when I turn the wheel too far right or left when I back out they do rub against the front part of the wheel wells. However I am having trouble understanding what the wheel weights are and how they are causing rub on the rotors, I inspected the rotors and they seem to be ok. Was wondering if you could help me decipher the message. I should have asked at the shop but left without really reading the packet since they said everything looked good.

 

So they did rotate the tires. So the truck has the TRD big brake kit on the front. Do you think they mean once they swapped the rear wheels to the front, the wheel weights on there rubbed and therefore removed them? I did notice that something small on the inner lip of the rims looked like it was taken off now that I think about it.
