To start off the weekend i took my evo to Altered Atmosphere Motorsports to have their new intake installed and do a couple dyno pulls. Everything went well, the intake sounds awesome, and boy so does that stock BOV. Drove it all day sunday, and it was flawless, but at around 9 pm on sunday night the car stalled in the middle of a turn at around 15 mph. The engine completely died, but everything else in the car remained on and working properly.i tried starting it again, and no dice. the starter motor cranked and turned over the engine, but it didnt fire up. After checking over the distributors, plug caps, and fuses, i was stumped as to what the problem was. So i got it towed this morning to Altered and they checked the car over, nothing seemed out of place...then they brought out the diagnostic scanner. They told me my crank angle sensor is not working, and i need a new one . $75 for the sensor and $225 for install. I didnt want to take my car to the dealership in fear of my warranty being blown over this sensor. I asked Alex at the shop whos got a sweet evo with 368whp, and he said he hasnt had this problem and niether has anyone else he'd talked to.

So i guess this blown sensor is just a defective piece, but has anyone experienced this yet?


Thanks

 

Why does it cost so much in labor to replace this sensor? It is easily accessible on the front of the engine....

SC~

 

This same issue happened to someone else on this board.. there engine stalled and
Like MalibuJack says in here.. it is possible that this sensor is knocked when installing anything from the intake side (intake, upper i/c pipes, etc.)

 

Hope someone pays for it - good luck

 

Buy the sensor and replace it yourself. A couple bolts, some grey RTV and you are done.

 

I broke mine when I took out the SSQV. The BOV was too big and rested on the sensor. I got a replacement from my dealer for under 50 bux.

 

so it's not really that hard to install the new sensor? would i have to lift the car to do it?...because this is the thing...the car is at altered and the part is on order...this isn't a how-to thread on this is there

 

Its pretty easy, the sensor itself basically held on by one bolt.. if the entire shutter wheel is damaged, then its kinda time consuming to do since the cover where the sensor is mounted would need to be removed.. But its all accessible from the top of the engine.

The car does not need to be jacked up to access.. if you look at the valve cover, its the wiring connector on the bottom right-corner of the valve cover (more or less) It has a weatherpack plug, and it sticks up slightly, the plug has 2 or 3 wires, and additional 1 wire (looks to be a ground wire)

if you look at your exhaust manifold head shield, the sensor is about 1" to the right, but on the side of the head, near the hose for your breather on the valve cover..


FWIW if the shop does it, its not more than 2 hours of labor, at the standard rate, 2 hours should not be more than $150 in labor. Parts should cost from $50 to $100 depending on if just the sensor is defective. If its just the sensor itself, it really should take about 25 minutes at most to install.

 

Hi,

I broke mine when adjusting my bov. Got a replacement from a dealer, but there was no way to plug the harness in, so I ended up splicing it. Another member recently posted a similar thing.

Anyway, I don't think it should be $225 to install, it easy except for the lack of harness plugging in. You can just kind of slide the 3 wires on and solder it...

Here are a couple of pics of my broken one:





See where the brown piece looks like you could unplug it and plug in the replacement? It doesn't really come apart, so I had to kind of hack at it. Ugly, but it works. I'm kind of surprised after reading how sensitive the thing is.

Take care,

hmmm...i might have to cancel the apointment for service and just get the part.

 

OK, I'm confused the thread title says cam angle sensor and your first post lists the crank angle sensor.

If it's the crank angle sensor, it's located behind the timing belt and balance shaft pullies (I think). There have been a couple of threads about problems with the crank angle sensor, but both were probably caused by debris getting down by the base of the timing belt.

If it's just the cam angle sensor it will be much easier.

 

He said camshaft angle sensor which si the one pictured above. Buy a replacement and screw it back into place. If they charge u 225 for install tell them to screw themselves. Takes less than 1 min to install

 

Yeah, I just went back and reread his post.. the title says camshaft, but the body says crankshaft.. A world of difference in the labor to replace the crank angle sensor.

 

woooops you guys are right...i meant CRANK angle sensor (stupid mistake) as i said in the body of my post (if there's any way to fix the thread title that'd be greatly appreciated).. but yeah the one that's located towards the bottom of the engine by the pulleys is shot...

 

Yeah, thats gonna take a bit more effort to fix.. about 3-4 hours labor..

I guess something somehow got in there and thrashed it... its really rare to have the crank sensor (even the cam sensor) fail for no reason..

BTW, Either of those sensors going bad will result in a no-start symptom.. thats why doing an OBD-II scan is important.. Probably the most important "tool" you can get if you like working on your own Evo..
