How many crankshaft position sensors are on a 2011 GMC Terrain?

my car was hesitating to accelerate and even stalled a few times while on my way to work. i stopped by the advanced auto parts parking lot and turned the vehicle off then back on again and noticed the engine light illuminated. had the auto parts store clerk run a scan and we received the error code indicating a problem with the camshaft position sensor. i was about to just buy the part since it appeared to be an easy swap, but unfortunately forgot my wallet so have to go back tomorrow. was doing some research on the issue and read some threads where some ppl replaced 2 sensors in a 2012 model.
Experienced mechanics share their insights in answering this question :
Usually there will only be one crankshaft position sensor. However, there is also a camshaft position sensor as well. It is more likely that there is multiple cam sensors than crank sensors. It is possible for engines to have anywhere from one to four camshafts but all engines have only one crankshaft.

I would recommend enlisting in the assistance of a qualified professional to test the integrity of these sensors on your vehicle. If these sensors are malfunctioning, I would recommend replacing any sensors that are faulty. It is also possible that wiring issues or PCM issues may exist. Be sure to have these issues addressed as well during the inspection.

To avoid any unnecessary repairs, consider YourMechanic, as one of our mobile technicians can come to your home to diagnose the Check Engine Light further and help you replace your camshaft position sensor as necessary.

“name”: “What Happens When A Camshaft Sensor Goes Bad”, Some cars come with four sensors(four-cylinder engine cars, V6 engine cars, and V8 engine cars) whereas other cars come with six sensors(e.g V12 engine cars).
There are two different crankshaft position sensors on your vehicle, one designated “A” and the other “B”. Both of these sensors are mounted to the engine block.
There are two basic types of crankshaft position sensors: Magnetic Field (Variable Reluctance) and Hall Effect.
While the number can vary based on the age of your car, a new car should have four camshaft sensors, one for each camshaft. A camshaft sensor determines the exact position of your engine`s camshaft, helping your car keep your engine`s combustion running smoothly.
Usually there will only be one crankshaft position sensor. However, there is also a camshaft position sensor as well.
There is no difference. CKP is the abbreviation for crankshaft position sensor.
P0335 is a diagnostic trouble code (DTC) for “Crankshaft Position Sensor “A” Circuit Malfunction”.
How many sensors does a car have? The car engine alone has around 15 to 30 sensors that track all functions of the engine. In total, a car can have over 70 sensors that monitor various aspects of the vehicle.
Types of Crankshaft

There are three different types of cranks you can use in an engine. These types of cranks are around for a long time and are found in a lot of diesel and petrol engine. As the name suggests, these are made from Malleable Iron through a casting process.

Cam is short for camshaft, the engine part that opens and closes the valves to let the air-fuel mixture in and out of combustion chambers. Every engine manufactured today has, if not one, then at least two or more installed.
4 cylinder engines will have two oxygen sensors.
On a V-type engine, such as a V-6 or V-8, or a horizontally opposed engine, such as those used by Subaru, each cylinder bank has two camshafts, so there are four in total. Many OHC engines also have two intake valves per cylinder, or two valves per cylinder for both intake and exhaust.

Replaced Crankshaft Synchronizer, crankshaft position sensor, purge valve, and bank 1 o2 sensor
ANSWER : Hi there. One item that many car owners and even mechanics fail to swap out while changing sensors that trigger OBD-II codes is the wiring harness. More often than not, a loose connection will instantly trigger a code. This is the common problem when the lights and codes appear, but show no symptoms as it’s inconsistent. You might want to be proactive and replace those wiring harnesses to ensure problems don’t pop up when you can least afford them.

CHECK ENGINE LIGHT ON
ANSWER : The on board diagnostic (OBD) sets a pending code each time the ECU detects a problem. It confirms the code if it sees the same problem twice. So you’re really only dealing with the two codes : P0016 and 17.These codes are telling you that the timing between the crankshaft and the camshaft are off on Bank 1 (the driver’s side) cylinder bank. This could be a sensor error, a problem in the reluctor ring on the harmonic balancer, or a timing chain problem. Without doing a thorough diagnosis, it’s impossible to say what parts specifically need to be replaced. If you contact Your Mechanic, they can send a technician to your home or office to investigate the codes on you Mercedes and then let you know what it will take to fix it.

I have changed the camshaft position sensor, crankshaft position sensor, spark plugs and plug wires and there still is no fire.
ANSWER : Hi there. If there was a spark around the speed sensor as the engine was starting, then there is a major short in the ignition system. Check all of the wiring grounds and make sure that they all are hooked up and clean. If you are referring that the coils are sparking on the outside, then the coil has a crack on them and they would need replaced. I recommend seeking out a professional, such as one from Your Mechanic, to help you with your ignition system.
