If there is an issue with the camshaft position sensor, it can be easily replaced in order to fix it. However, if the error code remains on the dashboard even after replacing the sensor, a larger problem has arisen. The two most common codes associated with this issue are P0340 and P0011. These error codes can remain for a variety of reasons. In this article, readers will understand why these codes may stay despite replacing the sensor as well as possible fixes that could help them eliminate these codes altogether.

What Error Codes Show By Camshaft Position Sensor Problems?
Replacing the camshaft position sensor in a vehicle might result in error codes being displayed. This could include P0340, indicating an issue regarding Camshaft Position Sensor A circuit; P0343 referring to “Camshaft Position Sensor “A” Circuit High Bank 1 or Single Sensor”; P0345 meaning the bank two camshaft position sensor is sending an incorrect voltage reading; and P0011 which implies that the ECM/PCM of the vehicle cannot differentiate between desired and actual camshaft position angle. To ensure optimal functioning of your vehicle, it is important to identify and address these issues.
What Does P0340 Error Code Means?
Among the many errors related to camshaft position sensor, P0340 is a commonly occurring one after replacing the sensor. As many people may already know, the camshaft sensor is responsible for tracking and recording the speed and position of the rotation of its corresponding camshaft. It also synchronizes ignition as well as firing of coils. Both Engine Control Module (ECM) and Power-train Control Module (PCM) makes use of this data from Camshaft Position Sensor but if any discrepancy arises then PCM won’t be able to create appropriate spark timing or injectors settings. This then calls for activating or storing an error code P0340; which is similar to other code i.e., P0345 where incorrect voltage readings are obtained by PCM due to faulty electric circuit in CSP, however; since both codes indicate a problem with CSP they need proper diagnosis before rectifying it correctly.
Why Are You Still Getting Code After Replacing Camshaft Position Sensor?
After replacing the camshaft position sensor, it is common for users to get P0340 and P0011 codes. In order to remove these error codes, it’s necessary to perform a relearn process. Failure to do so may result in the code remaining on system. Other causes of this issue include installation problems with the new sensor and old O-ring still present, electric circuit or wiring issues, damage to the reluctor wheel or starter motor malfunctioning as well as potential wear and stretch of timing chain guide plates. Additionally, a faulty PCM can also lead to getting this particular error code.
How To Get Rid Of This Code? [ 7 Steps To Follow]
Relearn Or Recalibrate The Sensor
In some cases, the ECU may store data from an old camshaft position sensor after it has been replaced. This can cause codes to be thrown and must be relearned for the vehicle’s proper operation. To accomplish this task, follow these steps:
Step 1 is to turn on the vehicle and connect a scanner tool such as MaxiSys Scanner Tool. Select your vehicle brand and model or use the Auto Detect option which will automatically read your system.
Step 2 is to go to Diagnosis option in accordance with an image order found below. Step 3 requires users to proceed through Special Function section until reaching Cam Crank Relearn Option; then select OK when prompted by new window information about relearning sensor.
Finally step 4 entails starting engine while waiting for coolant temperature requirement before acceleration; once reached, process will occur automatically (Dodge Jeep Chrysler used to show process). Other vehicles should have similar processes though minor variations could exist between models or manufacturers.
Check The O-Rings
When installing a camshaft position sensor, it is important to use two O-rings for proper functionality. One comes with the sensor and the other must come from the car manufacturer. The camshaft position sensor will have an attached O-ring that can look like plastic ridge, leading many people to believe that one is missing. In this case, they may try to install an old O-ring onto the new part which can cause gaps and impede installation of the part correctly. To avoid any issues it is best to remove this older ring and use only original components provided by both parties involved in its assembly. Additionally, be sure to clean off all parts of the O-ring before installation as well.
Test And Fix Camshaft Position Sensor Wiring
If a vehicle’s Electronic Control Unit (ECU) is displaying an error code, and the relearning process does not solve the issue, it likely indicates that there is a problem with the wiring harness responsible for sending signals to the ECU. In order to identify and repair this fault, one must test the camshaft position sensor wiring harness.
The steps involved in carrying out such testing will vary depending on what type of vehicle it is; however, generally speaking there are three wires associated with this part–a power supply wire, sensor signal wire and sensor ground wire–which come in different colors according to model.
Using a multimeter set to PIN 1 allows one to check voltage levels for the power supply wire; if these read around 5 amps then electrical flow should be good. Testing continuity between both ends of each of these wires–the camshaft position sensor and Electronic Control Unit (ECU)–using a multimeter also needs to be done in order ascertain whether they are operating correctly or need replacing/repairing.
For anyone without technical experience or knowledge, it’s recommended that they seek help from an automotive professional who can carry out all necessary tests as well as any repairs needed.
Check The Reluctor Wheel
If the above method does not solve the issue, a further inspection of the Reluctor wheel is necessary. Adjustment of the camshaft position sensor with the Reluctor wheel teeth must be done correctly for successful results. Typically, sensors are aligned with 20th teeth of the Reluctor wheel but it is important to inspect this component for any broken or damaged teeth as well.
It is recommended that a professional mechanic should perform these checks and adjustments to ensure accuracy and safety when working on vehicle components. Furthermore, they can provide additional advice if needed to make sure your car runs smoothly in no time at all.
Inspect Timing Chain
Many professional mechanics have mixed reactions when it comes to the timing chain being responsible for an error code. If the other components are checked and the error codes remain, then it is likely that inspecting the timing chain could be the next best step.
If inspection of this component reveals that it is at fault, then replacement will most likely be necessary. The cost of replacing a timing chain can vary significantly depending on make and model of your vehicle; generally speaking, you should expect to pay anywhere from $200 to $1000 for a new one.
Inspect Starter Motor
The starter motor is an integral part of the ignition system, as it is responsible for initiating the signal transfer from the camshaft position sensor to the ECU. If the starter motor malfunctions, this can interfere with this critical process and consequently hamper engine performance. In such a case, professionals advise that one should check their starter motor at regular intervals so as to identify any issues before they become more serious. If a malfunction is detected, then repair or replacement of the starter motor may be necessary in order to restore proper functioning of the ignition system.
Inspect ECU
The Vehicle Electronic Control Unit (ECU) receives the signal from the Camshaft Position Sensor. If the wiring correctly sends the signal, a code may still occur due to an ECU malfunction. In this case it is important to check that the ECU properly gathers and distributes the signal to all other components of the system. If not, then repairing or replacing of control unit needs to be considered in order for any codes to be eliminated.
