Unfortunately, your question is very vague and hard to understand.

16 or 32 cam?
Usually your engine will have twin cams, or single cam.
Overhead cam(s) or not. You could determine if your engine
is a 4 or a 6 cylinder, and then you will generally find out how
many valves the engine has.

If you are in a 4 cylinder car, you probably have 16 valves if you have a twin cam engine.
If you have a single cam, 4 cylinder engine, then you will usually have only 8 valves.

The only way that you could end up with 32 valves, is if you have a dual overhead cam, v-6 engine.
Each head will have two cams, and each cylinder will have 4 valves then.

I hope that this is what you were trying to ask. :)

Which number in gm serial number is engine designation


The following link indicates where these numbers are located.

It includes an example breakdown of what the number means and that should assist in determining what number you are looking for.

The location varies by type of engine. But all are on the cylinder head block on a machined pad.

What does the cam sensor on a 01 malibu do


To answer the first question, "What does the cam sensor on a 01 Malibu do?": A cam sensor is actually a camshaft positioning sensor.

The Camshaft sensor determines which cylinder is firing to establish injector synchronization and coil firing sequence in DIS systems.

There is also a Crankshaft sensor which sets ignition timing, supply the RPM signal, and determines the engine speed.

The Camshaft Position sensor is typically located in the cylinder head of the engine and has a cylindrical portion that inserts into the head.

The Crankshaft Position sensor is normally located in the timing cover or on the side of the block with a cylindrical portion that inserts into the block.

You can read more about it here: http://en.wikipedia.org/wiki/Crankshaft_position_sensor

I would first check for any OBD codes- and based upon what the reader displays, work from there. You may also want to have a copy of your car's injector circuit and wiring diagram available; along with a troubleshooting and testing guide for same.

Here's a youtube link that gives you some idea regarding a car's injector system: http://youtu.be/JTCgUY51g0s

What is a engine censor


There are a number of engine sensors on any modern motor. These sensors gather information like rpm's, engine coolant temp, crank and cam position, oil pressure, air temp, and throttle position just to name a few. The cars PCM ( power train control module) uses data from these sensors to determine how to run the engine and if it is safe to operate the engine.

I have a 93 s10 with 2.8 throtle body it trys to start


You need to determine if the Cam Position sensor is bad.
You also need to test the MAP (Mass Airflow Position sensor is bad as well. If its backfiring then I would think it is the Cam position sensor. I can't tell you where it is because it's different on each model. Refer to a Clinton service manual for its location or call a dealer.
Wish I could give you more info.

I have a 2003 chevy malibu with 90,000 miles. i took it in for maintenance and the mechanic said that it was showing trouble code p0341. he said it was the cam sensor. yesterday when i went to start it, it...


if the cam sensor is bad, it will definitely not start. The cam shaft position sensor's function is: the engine speed and crankshaft position information is supplied frome a sensor which is usually situated at the front or rear of the crankshaft. note that distributor-located engine speed sensor are generally being replaced with crank shaft-located sensors,as worn disributor drives and associated components can effect the accuracy of the engine speed signal.

A camshaft position sensor,or cylinder identification sensor is used to determin the engine cycle position the information is used to provide individual cylinder ignition and injection cotrol.Many engine mangement systems use an inductive type of sensor that is located near the camshaft;when the camshaft rotates a single signal is passed to the ECU to indicate a reference point in the engine cycle

Gentlepersons... have 1992SL1 engine died... gong to replace it ,,, but all involved want to know engine type dual cam? vs ? ... can you tell me how to determine whats in the car now.. vin# nails it...


That is pretty easy. If your Saturn is an SL1 it is single cam if it is an SL2 it is dual cam. That is the only difference between an SL1 and an SL2 - Saturn didn't even bother to put a tag or emblem anywhere on the body to differentiate between the the two models. The 8th digit in the VIN will confirm this for you. If the 8th digit is "7" it is a Dual Overhead Cam (DOHC) engine. If the 8th digit is a "9" then it is a Single Overhead Cam (SOHC) engine. When you have seen both engines, it is pretty obvious by simply looking at them. The DOHC cam cover is much wider and has 2 "humps" with spark plugs and wires going down the center between the humps. The SOHC cam cover is narrow and the plugs and wires go down one side.

Also in the 1992 model year, the DOHC engine was equipped with Multiport Fuel Injection. (MFI) The fuel injectors (4 of them) were located in the top of the intake manifold. The SOHC engine had Throttle Body Injection (TBI) The two injectors were located in the throttle body.

I don't have any pictures of the cam covers, but I have pictures of the cam cover gaskets (AKA Valve Cover Gaskets) you can very easilly see the difference.

I have 2006 hyundai elantra with a bad camshaft sensor. I have part on hand. Anything special I need to do besides swap out the part? Cam Shaft Location?


I assume you determined the diagnostic trouble code for the sensor was TRUE/VALIDATED?
If so, then there is NO reason to do anything else but 'swap out the part.' Your second question is somewhat puzzling... the cam shaft is on TOP of the engine - the sensor's location (standing on the passenger side of the vehicle with the hood open, is on the left side of the engine at approximately the 10 o'clock position of the cam.... the connector to it is at the 9 o'clock position.

Would a bad crank sensor cause car to loose power? I went over a speed bump and car just stopped


Actually, On 2006 vehicles the camshaft position sensor senses the TDC point of the number one cylinder, on its compression stroke. Its signal is relayed to the ECM to be used to determine the sequence of fuel injection. The Crank sensor is used to determine RPM ranges The crankshaft position sensor consists of a magnet and coil. The voltage signal from the sensor is relayed to the ECM to indicate engine rpm and the position of the crankshaft. This sensor wouldn't affect your performance but, the Cam sensor will if its damaged. To answer you question correctly, it would be the cam sensor i would check. it actually controls the injection system. if damaged, it will cause performance issues. On 2006 vehicles the crankshaft position sensor is located next to the radiator hose inlet and outlet assembly. On 2006 vehicles, the camshaft position sensor is located on top of the engine, on the engine head cover.
