What causes code P0344?
Diagnostic trouble code (DTC) P0344 stands for “Camshaft Position Sensor “A” Circuit Intermittent (Bank 1 or Single Sensor).” It triggers when the PCM detects a loss of signal from the Bank 1 camshaft position sensor. Bank 1 refers to the bank of the engine that contains cylinder #1.

What repairs can fix the P0340 code?
- Repairing or replacing the camshaft position sensor circuit wiring.
- Repairing or replacing the camshaft position sensor circuit connector.
- Replacing the camshaft position sensor.
- Replacing crankshaft position sensor.
How do you fix a camshaft position sensor?
How to Replace a Camshaft Position Sensor
- Disconnect the negative battery cable.
- Locate the sensor.
- Release the tab on the sensor to disconnect the wires from the sensor.
- Remove the mounting bolt which attaches the sensor to the engine.
- Pull the sensor off with a slight twist.
Where is the camshaft position sensor located?
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.
Where is camshaft position sensor a bank 1 located?
Beneath the timing belt cover is where the CMP Sensor is mounted. The camshaft position sensor can be found in the right side of the engine compartment at the rear of the valve cover.
What is P0345 engine code?
The ECM uses this information to control ignition spark and fuel injector timing. When the trouble code P0345 is set, the ignition spark and fuel injector timing fail due to the engine not knowing when to fire these components.
What is a camshaft bank 1?
Alternatively, if the engine employs a V configuration, the “A” typically refers to Bank 1’s intake camshaft. Finally, the “bank 1” in the P0341 code refers to the side of the engine where the number one cylinder is located.
How do I fix code P0345?
What repairs can fix the P0345 code?
- Replacing the crankshaft position sensor.
- Repairing or replacing damaged wiring.
- Repairing loose connections.
- Identification and repair of fluid leaks.
Does camshaft position sensor affect oil pressure?
If the oil level is very low, to the point where the engine overheats however, yes. Excessive heat can cause a camshaft position sensor to fail. More likely in a “low oil level” situation is for the camshaft, lifters, or camshaft variable timing actuator to fail due to inadequate oil pressure and lubrication.
What does P0335 mean?
P0335 is a diagnostic trouble code (DTC) for “Crankshaft Position Sensor “A” Circuit Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
How much does it cost to replace a camshaft sensor?
The average cost for camshaft position sensor replacement is between $176 and $227. Labor costs are estimated between $72 and $90 while parts are priced between $105 and $136. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
How do I know if my camshaft position sensor is bad?
If your vehicle idles roughly, stalls frequently, has a drop in engine power, stumbles frequently, has reduced gas mileage, or accelerates slowly, these are all signs your camshaft position sensor could be failing.
What happens when camshaft position sensor goes out?
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.
What causes camshaft sensor failure?
There are many reasons why the camshaft position sensor could fail. Some of these include wear-and-tear, water damage, and oil embedded in the engine. There are also sensors that fail due to corrosion, which is a common problem for camshaft position sensor circuits.
Do you have to replace both camshaft sensors?
Do you have to replace both camshaft sensors? Experts recommend replacing both camshafts at the same time. The replacement process of the camshaft and the crankshaft is the same. But, you may face difficulty while detecting the location of the crankshaft.
Should camshaft sensor have oil on it?
It’s a normal thing for a camshaft position sensor to have oil on it. The oil is necessary for its functionality. However, the sensor housing has to be in good shape to work perfectly. A crack in the sensor housing can result in oil contamination which could make the sensor fail.
Is it hard to replace a camshaft position sensor?
If you determine the camshaft position sensor is the problem, the good news is that replacement is usually very simple, if you can easily gain access to the sensor. The CMP sensor is mounted in several different places, depending on the model.
How many camshaft sensors are in a car?
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.
What is the difference between crankshaft position sensor and camshaft position sensor?
The main difference between the camshaft and crankshaft position sensors is that the camshaft position sensor is used to find the position of the camshaft while the crankshaft position sensor is used to detect the position of the crankshaft and piston.
What side of engine is Bank 1?
Both bank 0 and bank 2 refer simply to either side of the engine’s cylinder 1. Bank 1 appears on the left side while bank 2 appears on the right. Two cylinders stand on one side of the bank 2.
What side is camshaft sensor bank 2?
Bank 2 will be the right side of the motor when you’re looking at it. Sensor A should be the intake cam sensor.
What is P0012 code mean?
P0012 is an OBD-II generic trouble code which indicates a vehicle’s ECM (engine control module) has detected the intake camshaft timing on Bank 1 (number 1 cylinder side of engine) does not correspond with the intake camshaft timing (in degrees) which the ECM expected to find
the camshaft timing is over-retarded, …
What is the camshaft position sensor bank 2?
The CMP sensor measures the exact rotational position and speed and position of the camshaft. The data that the CMP gathers is important because it’s used by the ECM to control the ignition spark and the fuel injector timing.
Is Bank One an exhaust or intake?
Bank 1 is the side of your engine that has the cylinder 1, while sensor B refers to the exhaust camshaft side.
Can you drive with P0341?
Trouble code P0341 should be diagnosed and repaired as soon as possible. Not recommended, however, you may drive your vehicle while trouble code P0341 is present unless the engine stall or stumbling is is severe enough to hinder proper vehicle operation. Erratic engine speed may be noticed.
When should a camshaft position sensor be indexed?
To establish camshaft sensor indexing on a vehicle with an adjustable sensor, all of the following are true, EXCEPT: attach a lab scope to the crankshaft position sensor signal wire. attach a lab scope to the camshaft position sensor signal wire. start the engine, observe the lab scope and compare the readings.
What is the code for a bad camshaft sensor?
What Does Code P0340 Mean? The OBD-II diagnostic trouble code P0340 indicates a “Camshaft Position Sensor “A” Circuit Malfunction.” It covers the entire circuit attached to the aforementioned sensor, such as the electric wiring and the powertrain control module (PCM).
