Fwiw EGR probes are almost always run-of-the-mill Type K thermocouples. Readily available from hundreds of places in dozens of configurations. Omega Engineering is one source with a good selection...

As I've said many times here don't do load dumps!

Geared mainly to OBD-II but Chapter 8 is worth reading because it's applicable to any system. Rather simple knowledge compared to what's needed in California though...

Where on that schematic do you not have power? Does the power seat work? Does the window operate if both driver and pax switches are held down at the same time?

L is just what it says, for the charge warning indicator. The regulator grounds L to light the lamp. B is, as you surmised, the alternator's output to the battery positive terminal. S is the Sense wire. It's used by the regulator as feedback so the regulator can adjust alternator output as...

Probably a lot more than you wanted to know but: http://tinyurl.com/2clm6wj

When the difference in pressure *across* the filter media exceeds the bypass valve rating it will open, allowing oil to bypass the media. That can happen for reasons other than the media becoming restricted. And a larger filter does nothing except increase holding capacity...

I'm afraid you're confusing the air bleed idle-up feature with PPS. Different systems with different functions. Not solenoid. Proportional control valve. Close enough for this gang though...

People can do as they wish but Toyota put it there for a reason and I'd personally rather not be inhaling CO should an exhaust leak develop. I suppose the argument could also be made that removal cuts airflow over the bell housing and transmission (assuming the undercover is in place) but I'm...

It can be messed with on a GTE (although it shouldn't be) but don't do it on a GE. It serves a different purpose on that engine, which is why the screw position is coded onto the housing of N/A flow meters but not on the Karman.

It won't do much other than allow engine stink into the fresh air vents. Keep up on maintenance and there's no need for worry. In 22 years of driving under all sorts of conditions the Sonalert wired to the #2 water temp switch on my car never once sounded. That means the coolant never went...

He's predictable, I'll give him that :)

Clear the codes and see what comes back. It's likely the 51 will. If it does you'll have to check the TPS. See the TRSM for details. If you don't have one ask member JStoked to look in his...

I applaud his thoughtfulness but without solid metrology it's just that. Me thinks he thinks too much. Crisp: Too much instrumentation and data, or having it presented in wrong way, can be more hindrance than help. Even when it's installed and displayed correctly it can show all sorts of...

The radiator is likely at fault. I say likely because since you didn't say how the fan clutch was determined to be working properly we have nothing but your word to go on.

But it's OK others spent the $70 (which it doesn't really cost) so you could suck on their teat? How enlightening...

Rather than go off on a tangent about how cooling systems work I'll point out a couple of things: 1) You have a history of over "anal-yzing" stuff, to your own detriment. Even when something is understood that's a bad approach but analysis on any level without knowledge to back it up leads...

Why do so many think CFM is all important? It's not. In fact too much is a bad thing. And assuming his fan clutch is working this guy's problem doesn't involve airflow through the radiator anyway. He already proved that in a prior post...
