What does the P0016 code mean?

The DTC P0016 is commonly a form of the generic powertrain code which suggests “Camshaft Position A – Camshaft Position Sensor Bank 1. ” We know that both the camshaft and the crankshaft have a deep correlation. Actually, they work harmoniously; thus, the processes in the main engine perform well. You need to know that your vehicle’s PCM (Power Control Module) is mainly accountable for the frequent rotation of both the camshaft and the crankshaft.

There are two individual types of sensors called the camshaft sensors and the crankshaft sensors. Their work is to monitor and provide basic information regarding the rotation and movement of the cams crankshaft. If it finds any fault in the cycle, then it sends that message to the PCM, and eventually, the PCM commands the MIL or the CEL to blink and register the error code P0016. This is how the total system works to show up the error codes.

Quick Tips (Causes & Solutions)



Popular brands encountering the respective code:

P0016 Chevy, P0016 Ford, P0016 Dodge, P0016 Mercedes, P0016 Toyota, P0016 VW, etc.

P0016 Bank 1 Sensor A Location:

In most conditions, the camshaft position sensor is situated on the valve cover in proximity to the reluctance ring. And the crankshaft position sensor is located on the crankshaft pulley in most vehicles. Suppose the PCM finds anything unusual in the sensors. In that case, it immediately gives a notification to the check engine light, and then pertinently, the DTC P0016 appears on the screen of the scanning tool. p0016 bank 1 sensor a location

What are the prime causes of the P0016 code?

Although there are tons of causes that the P0016 code appears in the monitor of the scanning tool, here is a conventional list of what causes are the most prominent in happening of the error code P0016, 

Possible Symptoms of the P0016 code

The possible symptoms are not getting more prominent than the error code P0016 symptoms. Here are some of the possible P0016 symptoms, 

What is the diagnosis process of the P0016 code?

The first stage is to attach the OBD-II scanner to the car, check for the existing error codes and read the freeze frame data inspecting the rotational graph of the camshaft and the crankshaft. Diagnose the entire sensor system of the camshaft and the crankshaft. Diagnose the timing components properly. Check If there is any tear or missing tooth in the timing chain. Diagnose the oil control valve and check for possible sludge and impurities in the pathways. Examine the oil filter and replace it if it is outdated. Last, diagnose the PCM if it can carry correct signals to the MIL or CEL.p0016 bank 1 sensor a location

Avoid common mistakes when diagnosing the P0016 code

Even an experienced mechanic can make mistakes while diagnosing the error code P0016. Sometimes the problem is manufacturer specific instead of generic. So we suggest checking the technical service bulletin (TSB) before starting the diagnosis. Some mechanics may skip checking the engine’s fuel level or forget to check the timing components. Some internal wiring issues may also occur, which might remain unnoticed; recovering all these faults while diagnosed may save you valuable money to a greater extent.

How dangerous is the P0016 code?

We know that most of the generic powertrain codes are not suitable for the main engine. They can cause extreme havoc to the entire engine module. Both the camshaft and the crankshaft are harmonized with a timing belt series that operates the procedure as the whole of the engine. Note that if the timing components are out of sync, it might collapse the entire engine’s workability. Belts as a whole may be snapped or broken as they are made of pure rubber, and they can not bear extreme temperatures. If this happens, the camshaft and the crankshaft rotation may have been poorly disrupted. Continuously driving the car and ignoring the error code may be proven to be one of your biggest mistakes. Neglecting the fault code may add some extra dollars to your repair bill. 

How to fix the P0016 code?

Fixing the issues of the error code P0016 is an expensive and lengthy process. And if the code has affected the internal camshaft section, then the overall Maintenance cost will soar up to the limit. Here I am describing the whole fixing process of the error code P0016 parts by parts,

First of all, take an intelligent OBD-II scanning tool and check for error codes. Connect the scanner with the main interface of the vehicle and wait for a while to receive the error codes. The scanner may show up with one or more than one error code regarding the issue in the camshaft segment. Once you see the codes on the screen, note them down and check for the manufacturer’s specific service manual.

After successfully registering the error codes, you need to check the engine oil level. If the engine oil level is insufficient, add some fuel to the engine. Check If there is any kind of debris or impurities in the oil or if the oil’s viscosity is correct. You have to remove the oil plug, drain all the contaminated soil, and then dispose of that impure oil while maintaining proper safety precautions and changing the oil filter to get the maximum output. Apply the correct viscosity of oil into the tanker and close its opening. Now your car is good to go.

The voltage is to be at the suitable standard to operate all the procedures smoothly. Use a voltmeter and check the relative voltage of the camshaft oil control valve. If the voltage is higher or pretty much lower than the actual standard, you need to replace the valve as soon as possible.

The sensor is one of the most valuable components in the engine. Simple mismanagement in the engine may lead to a complete collapse of the main engine. The first duty is to locate the camshaft and the crankshaft Sensors and examine if there is any discontinuation or leakage. Introduce a digital multimeter to examine the actual resistance of the sensors. If the resistance value is between the standard level, your sensor problem is successfully solved.

The timing component consists of the Timing Belt, Camshaft pulley, Tensioning pulley, Crankshaft pulley, and Idler. Altogether they operate the Camshaft and Crankshaft. If you notice wear or tear in the timing belt, make sure that it is repaired. Some teeth of the belt may be missing or may be broken. Repair them. Investigate all the parts individually to see if they are operating correctly.  

It is time to bring back the OBD-II scanner and rescan the vehicle. This time, you may have no codes jumping into the scanner’s screen or one. Try to delete the inactive codes and scan once again to eliminate the error codes totally. 

How much money do you need to fix the DTC P0016 fully?

A bunch of repairs are needed to solve the error code P0016. All the service charges may include the cost of the related parts and the labor cost. The initial stage is to change the Engine oil and filter, which might cost around $20 to $60. Repairing both the Camshaft position sensor and the crankshaft position sensor can cost you between 170$ to 230$ individually, and if you have an issue with the reluctor ring, you have to spend between 200$ and to 600$ inclusive. If the mechanic finds any fault in the timing belt, he may charge you around 300$ to 400$, including all the hidden charges. Last but not least, to fix the timing chain, you need to spend between 1500$ and to 2000$, which is quite a tremendous cost for you.

Final Overview

The problems in the camshaft and crankshaft may be proven a troublesome chore for you. It can cost a huge sum of money to fix the issues. But if you follow the above guidelines, it is possible to repair the problems yourself. Give it a careful try, and do let us know if the guidelines were helpful to you.
