Where is the downstream 02 sensor located?
The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter. The upstream sensor monitors the level of pollutants in the engine's exhaust and sends this information to the ECU that continuously adjusts the air-fuel ratio. Click to see full answer. Also question is, where is the downstream o2 sensor located?
Is cam sensor and crank sensor the same?
Cam sensor and Crank sensor are not the same. The Cam sensor is mounted on the Cam shaft and Crank sensor on the crankshaft. Both are used to measure the engine rpm. Typically, the crank sensor is the primary sensor and the cam sensor is the back-up sensor.
Where is the cam sensor located at?
The camshaft position sensor is always located near the camshaft, often at the top of the valve cover, but it can also be installed from the side of the cylinder head. Check around the head or valve cover and follow any electrical wires and you will for sure find the camshaft position sensor.
What are the symptoms of a faulty cam sensor?
Poor Drivability A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.
How many cam sensors are in a car?
four camshaft sensorsWhile 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.
What problems can a faulty cam sensor cause?
If the sensor does not work properly, many symptoms may arise. Usually, a check engine light will turn on. Other symptoms include bad gas mileage, rough idle, engine stalling, and engine power loss. Each of the symptoms might be hard to differentiate.
Is it easy to replace a camshaft sensor?

Will a bad camshaft sensor throw a code?
Answer: Usually a camshaft sensor intermittent failure can produce no code. But you'll notice a change in driveability performance at times. Sometimes it's possible to detect the failure with a scan tool.
What does a broken camshaft sound like?
The symptoms of a bad camshaft include frequent backfiring and popping. You may also experience cylinder misfires at low and high speeds. Additionally, if your camshaft lobes are worn, you may hear tapping and ticking noises from the upper engine.
How long does it take to replace a camshaft sensor?
Can You Replace a Camshaft Position Sensor Yourself? Yes. This is one of those jobs that almost anyone can do and is an easy way to save yourself the minimum labor fee (often close to $100) that a repair shop or dealership will charge you. It should take about 5-10 minutes to replace it.
Can a camshaft sensor cause a car not to start?
Car Will Not Start: Over time, as the camshaft position sensor fails, the signal it sends to the engine control module weakens. When the engine no longer receives the signal, you will not be able to start your car.
How long does it take to replace a crankshaft sensor?
In most instances, this repair should take no longer than one day.
Is it worth replacing a camshaft?
Due to the manufacturing processes, repairing a camshaft is not often advisable. While some high-performance engines use camshafts that are repairable, it's not really cost effective or practical for the average car on the road. Instead, if your car needs a new camshaft, replacing it with a new one is the best choice.
What is a crankshaft position sensor?
The crankshaft position sensor (CKP sensor or CPS) is one of several sensors that keep your engine running smoothly. It measures the position of the crankshaft (for which it is sometimes called the crank angle sensor or CAS), as well as the rotational speed of the crankshaft (for which it is sometimes called the engine speed sensor, ESS, ...
What is a Hall Sensor?
A Hall effect sensor produces electricity in when it is exposed to a magnetic field. In a crankshaft position sensor, a toothed wheel, spinning with the crankshaft, disrupts the magnetic field. That produces a pattern of on and off switches in the Hall Sensor that the ECU can interpret as the crankshaft speed.
Where is the timing cover located on a car?
Obviously it must be close to the crankshaft, so it is most often located on the front underside of the engine. It can usually be found mounted to the timing cover. Sometimes it may be mounted at the rear or the side of the engine. Sometimes the crankshaft position sensor measures the speed of the clutch flywheel to determine the speed ...
How does a sensor produce voltage?
The sensor produces an electrical voltage based on fluctuations in a magnetic field. The fluctuations are caused by the movement of metal pins in the crankshaft. Faster spinning means more fluctuations and more voltage. The ECU is able to translate this voltage into crankshaft speed. In either case, the timing elements, ...
Where is the camshaft position sensor located?
The camshaft position sensor is always located near the camshaft, often at the top of the valve cover, but it can also be installed from the side of the cylinder head.
How to tell if camshaft sensor is bad?
The most common sign of all bad camshaft position sensor symptoms is that the car will be more difficult to start or not starting at all. As the camshaft sensor becomes weaker, it does not send the signal to the on-board computer and as a result, the ignition system cannot produce a spark correctly. No spark means that the engine will not start ...
