How many crankshaft sensors are there on a Cadillac CTS 2007?

One crank sensor. It needs to go on a scanner. Both sensors are probably OK. Your problem is most likely the timing chains or guides. If ti were the crank sensor, it wouldn't start. Cam sensor would throw a cam code. Correlation means the crank and cam are not in sync. If you have VVT, it could be the actuator.

Replace crank shaft sensor

how to? who can, where is it? ask a real question.
Ill answer how can it tell , its bad.
these cars can have 2 or 3 engine options, to work on any
cars engine, you first need to find out, what engine it is?
mine is 2.5L V6, my last one , was 2.0 I4 .

why do you think its bad? is the ECU sending trouble codes, DTCs
for this sensor? either running or cranking, if not ,its not bad.
easy huh?
here is the scan list P0355 is the CKP sensor (crank)
got 335's? is that it?
The fact is the ECU is real adept at reporting this sensor bad.
even if it misfires 1 in 10 times. really

2004 nissan altima S service engine light is on again after having crank sensor and cam sensor replaced along with 4 coil boots and 4 spark plugs. This service was performed about 2 months ago. Sometimes...

Have the vehicle scanned again to see what codes you get. Its possibly either mismatch firing order with the coil boots or hairline cracks in one or more of the spark plugs. I'd remove them and closely inspect the ceramic for damage, even the most minute crack can cause an arc. Then there is always the possibility of faulty sensors.

I have a 2004 nissan altima, i have the my check engine light is on and i had the code checked which was a P0340 camshaft position sensor. i had both the cam and crank replaced and had the light reset so...

I doubt very much that you are looking at a faulty mass airflow sensor. I can tell you from my 25+ years of experience that the most common cause unless the camshaft position sensor is bad is there is a bad ground. Below is a pictire of the plug for the sensor. What you need to do, with an ohm meter is check for continuity between terminal 1 and the engine ground. If you do not have continuity this would be the problem of why the code is setting and the wire needs to be repaired. Like I said this is the most common that I have come across. There are many different reasons as well as many different tests that can be done but I would start there. The bad thing is that many of the tests are going to require the proper equipment which most people do not have in thier tool box. If you are in need of more testing procedures or any other information on this code which basically says it's a fault in the camshaft position circuit, feel free to email me at with detailed questions so i am sure to send you the right information. I hope this helps and good luck.

There are so many sensors on cars now a days its hard to say, i can take a guess,you may need cam and crank sensors and the other sensors may be the oxygen sensors, this car is a 2005 this many sensors going bad at once is crazy, even with 100,000 miles on it, i would have a second reapair shop or dealer look at it,

My check engine light is on and I've been told it is the cam sensor, but I can't find one. It's a 2005 nissan altima. Do they have a cam sensor and a crank sensor?

This engine has both. Nissan recommends replacing them at the same time, I think your local Nissan dealer will tell you the same thing.The cam and crank sensors are in the rear of the engine.Looking from the drivers fender find the right rear corner of the valve cover and look straight down the back of the head. the cam sensor is 3-4 inches down from the valve cover gasket surface.the crank sensor is basically straight down from the cam sensor but much harder to see. it is just above the oil pan gasket surface...
