Whats That? (New 3/20 - ANSWERS POSTED)

[Jeremy airjer W]

Last week was pretty easy so I thought I would throw in a few that are a little harder. I post the answers in a couple of days.

Part A

Part B

Part C

Part D

Part E

[Scott K]

I know them all except E, I have an idea, but dont know for sure.

[Shack]

Airjer is getting good . Ya, the "E" one I know what it is (I think), but make model and year, no way!!! "C" image makes that thing look huge, but it is small (looks like the size of an EGR valve).

Good luck folks

[Jeremy airjer W]

The only V-8 that has one would be the Tundra.

[BoxMN]

I have no idea on any of them...

Now if ya'd start slow like say a screwdriver,pliers,wiper blade,muffler,ingntion key, I'd play,but I'm taking screwdriver home and wont play your game.

[GAP]

Ha Ha i'm with sparcebag on that

[Jeremy airjer W]

LOL! Stick with it guys. I'll give you a full explanation of what they are and what they do. You might even be surprised that to find out that you have had one of these replaced in the past.

On a side note, I plan on throwing in a few specialty tools every once and a while.

[Dozer]

I guess I will have to be the first to post some guesses.

A No idea

B Throttle position sensor?

C Fuel pressure regulator (for a 3.1 Gm?)

D Coolant temp sensor

E Hyd clutch cylinder?

[Sandmannd]

I'm a mental midget when it comes to mechanice. Through some computer parts up there so I can show off airjer.

[Black_Bay]

Hmm These are a bit, ok a lot, tougher for this shadetree mechanic.

Part A - MAF

Part B - ??

Part C - Something vacuum operated

Part D - Temp sensor. I'll guess it's a GM product because it looks cheap and plastic.

Part E - ?? By the look of that I hope it's off an older model Tundra and not a new one.

[lotsofish]

A is a mass airflow sensor?

B I know for sure. It's a pressure sensor from a GM 3.8L that connects to the PCV housing on the uim.

C is it a fuel regulator?

D I agree with temperature sensor, but it might also be a coolant level sensor.

E Dunno??

A cracked block?

Sorry, I couldn't resist. Great game. You stumped me on this round.

Seriously, on the last round about the camshaft....did you run into a lot of these? Do you work for a Toyota dealer? Just curious on how many camshaft issues there were. Based on the recall it sounded fairly widespread. I read that one of the higher ups commented on how disappointed he was in the quality of Toyota and said that their large growth wasn't an excuse....quality control needed to be addressed. Pretty big for him to say that.

[muc33]

They all look like the spark plugs in my diesel! I just didn't know they came in so many varieties.

That is why I pay mechanics.... cuz I is dum!

[Scoot]

A: Widget

B: Pito

C: Thingy

D: Whatchamacallit

E: Thingamajiggy

How'd I do?

Scoot, so your the guy that comes to the parts counter and asks for parts! I swear those are the most comonly asked for parts

[Surface Tension]

Nice game.

I wish I would've taken pictures over the years of wee parts.

Do you parts counter guys get any one in looking for a "johnson rod"?

[Scott K]

Im really not a parts counter guy, I am the one who repairs them. I just have heard them terms, and know that I have used them many times! No johnson rod talk for me!

[PierBridge]

I'm going with hydraulic timing belt tensioner for E.

It's the new EJS on Tundras.

[Tom7227]

How about tossing in a part from a car that was built back in the old days when a guy had a chance to do something more than change his own oil? I think it's been nearly illegal for a back yard kind of guy to even open the hood of a car built since 1990.

[Jeremy airjer W]

Hang in there Tom, I have some parts from the old days! (Even though I'm not old enough to know what they are )

Valv, What's an EJS?

Limit, I know that it was/is a pretty big problem as far as Toyota's momentary lapse of reasoning goes. All of these have been dealt with by the dealer. From what I understand if the cam broke the engine (long block) was replaced. I am lucky enough to work for an independent shop.

[Jeremy airjer W]

This was a little tougher but still a few good guesses. Here are the correct answers.

A. This is a Mass Air Flow (MAF) sensor out of a 99 Ford Explorer. A similar looking sensor can be found in many vehicles while others MAF sensor may look entirely different. Its primary function is to figure out how much air is going into the engine. I picked this sensor partly because of its susceptibility to contamination which will cause all kinds of issues. Poor idle, no idle, poor acceleration and no power are a few of the complaints caused by these sensors not functioning as intended. More often than not a quick cleaning is all that is needed to cure the problem.

B. The MAP sensor which is often confused with the MAF sensor has come a long ways. Older Chryslers where notorious for the start and stall symptom that these sensors would have when they failed. The function of the MAP is to measure the difference of pressure between the atmosphere and the intake manifold. This information along with other info is then used to calculate air density which is one of the calculations used to determine correct fuel delivery. It can also be used to test whether or not the EGR is functioning. This particular one fits a variety of GM V-6 and V-8 from 95 to 01 and a few Isuzu engines as well.

C. The fuel pressure regulator is one of the most common repairs that I deal with. This style of regulator operates off from engine vacuum. When vacuum is high (engine idling) the fuel pressure goes down. When vacuum is low (engine accelerating) the fuel pressure goes up. The most common problem with these types of regulators is fuel leaking out the vacuum side of the regulator. When this happens fuel pressure drops and excessive fuel ends up in the intake. The drop in fuel pressure along with a hot engine causes the fuel to boil in the fuel rail (vapor lock) the excessive fuel in the intake causes flooding. That’s why the extended crank is typically more noticeable after a hot soak rather than first thing in the morning.

D. This is one of the famous speed sensor twins out of late model Chrysler transmissions. This particular one is an output speed sensor out of a 99 Caravan. This sensor is responsible for the signal that helps calculate gear shifting and the speed reading on the speedometer. If this sensor fails the speedometer stops working and the transmission defaults into second gear. I keep spares in our Town & Country!

E. This is a hydraulic timing belt tensioner out of a late model Honda V-6. These aren’t that common to replace but every once and a while you will run into one that is leaking.
