Fix Code P000A: Intake A Camshaft Position Slow Response Bank 1

You will obviously be acknowledged for the trouble codes if you own a car. These are mainly the irregularities of the vehicles. There are thousands of codes for the vehicle, and different regulations determine different parts of the car. The code P000A that we are going to address is generally a generic powertrain code denoting problems that happened in the vehicle’s main engine. This article will demonstrate the actual causes, symptoms, diagnoses, and possible repairing methods that may help fix your car by yourself. In case of extreme contingency, you need to seek help from professional mechanics.  

What does P000A Code mean?

Before we dig deep into the article, the first thing is to know about the error code in short. What does the code P000A actually denote? The Fault code P000A means the  “A Camshaft Position- Slow Response Bank 1,” The PCM (Powertrain Control Module) detects an irregularity in the actual position of the camshaft when it does not match the original position in the camshaft or shows an unwaved position. The camshaft behaves abnormally or, to be precise, slowly, and it fails to command the advance or delay valve timing on the bank of cylinders originally noted as cylinder number 1. The PCM can rotate and regulate each of the camshafts, and it can also monitor the applications of VVT or VCT. IT is the PCM that controls the real appropriate valve timing strategy based on the current speed of the engine. how do i fix p000a code

The camshaft has specific sensors and connectors that give information to the crankshaft and the engine’s core parts. If the sensor does not work properly and fails to produce the actual notation graph, then it is assumed that there may be some issues in the sensor of the camshaft. When the PCM realizes that there is an uneven movement in the camshaft, it sends a notification to the MIL or CEL, and it suddenly starts to blink. That’s how the entire process goes, and the error code P000A is illuminated on the screen of the dashboard.

Where is the P000A sensor located?

The P000A sensor is generally located in the camshaft compartment where camshaft position sensors and the exhaust camshaft’s position sensor are situated. It is noted that the cylinder head and valve cover also operate to the camshaft’s closest proximity. All the parts and components are needed to be located correctly to operate a maximum camshaft’s movement.

What are the actual Causes of the P000A Error Code?

There are tons of causes to form the error code P000A. The possible causes may be,  

  • The wiring must be corroded, damaged, burnt, or shorted in the camshaft position sensors’ control/signal circuit area. The oil control solenoid itself and the camshaft actuator may be hampered due to the contaminated engine oil. 
  • Defects may be generated in the oil control solenoid, camshaft actuator, and the camshaft position sensor. The failure in the positioning sensor might cause trouble in valve timing management, engine speed sensors, and pedal position sensors. All these sensors might be affected badly, and the discrepancy may occur among them if the camshaft’s position sensor behaves unnaturally.   
  • The timing chain might be worn out, or the associated tension devices, sprockets, and guides might be out of order. A fault in the VCT (variable cam timing) phaser could also be proven to be harmful.
  • The PCM may fail to operate, or there may be some irregularities in the PCM’s memory. 

What are the Natural Symptoms of the P000A code?

The error code P000A exceeds some of the common symptoms from which we get to know about the details of that error code. Let us see some of the symptoms of the error code P000A.  

  • The MIL or CEL starts to illuminate, denoting that the error code P000A might have occurred. The engine may extract to show shabby performance. 
  • The fuel use got increased as the fuel economy was hampered severely. The engine may extract the rattling noise that impedes gas and fuel emissions management.  
  • The limp mode will turn on and create a stalemate in the car’s function. 

How to Diagnose the Fault Code P000A?

The fault code P000A can be diagnosed in several phases. Innova 3040 would be the best scan tool to diagnose the problem. For your convenience, I am going to phase it out, 

  • Engine Oil Diagnosis

The engine oil is the prime factor that remains the engine active, and for that, the very first diagnosis we will perform is the engine oil diagnosis. The camshaft position solenoid circuit should remain open during the diagnosis. The oil pump solenoid or engine oil pressure sensor must be diagnosed before further proceedings. This diagnosis step includes checking the low engine oil level, inappropriate oil viscosity, engine oil pressure, the engine oil filter, and so on. Remember that the ignition must be turned off before performing the diagnosis. The mechanics may clear the oil sludge, seal the pick-up tube, and damage the fuel pressure valve after making the diagnosis. 

  • Check the engine oil pressure

After the diagnosis of the engine oil, the next step is to examine the engine oil pressure. Install an adapter to the oil filter cap and see if any harmful conditions are available in the adapter. Turn on the engine and let it remain idle for some time; after a while, scan for the oil pressure, and if the reading gives around 10 Psi pressure, then it is wobbling intensely.

  • Verify the Cam Phaser position 

The subsequent diagnosis is about pinpointing the cam phaser position. The cam phaser basically controls the camshaft, and it is a mini-computer attached to the camshaft. The main duty of the cam phaser is to adjust the position of the camshaft related to the crankshaft and the pistons. p000a dodge

Then the subsequent diagnoses are the wiring and the connectors. You need to ensure that the connection between the wirings is stable and that each of the relationships regulates properly. The gears of the crankshaft should Also be examined. 

 What Parts Needed to be Fixed?

The error code P000A generates when the parts related to the camshaft show abnormality. A set of parts needs extensive care to work as the initial condition. The parts which are associated with the camshaft and need scrutinization are discussed below,

  • VVT actuator and VCT phaser

The Variable Valve timing, or the VVT, is solely situated in the main compartment of the camshaft. It welcomes a signal from the engine control system that is divided into small sections of timing. The VCT phaser is the component that utilizes the energy, oil pump flow, and the actuation of the camshaft. These two portions need to be repaired in case there exists any fault.

  • Camshaft position sensor

This is one of the main parts of the camshaft; the sensor maintains the connection between the algorithm and the information within the camshaft and the crankshaft. If it gets damaged, no other parts in the camshaft may work properly.

  • Oil control valve

The valve that governs the flow of fuel into the camshaft is rendered as the oil control valve. It strengthens the interconnection within the moving parts of the engine.

  • Timing chain

The timing chain is the main attribute that governs the pistons and valves in the camshaft. They are situated in the engine cylinder and make the engine work effectively.

  • Timing Belt and Belt Tensioner

The vehicle timing belts maintain synchronization between the rotation of the crankshaft and the camshaft. If both of them have disabilities between them, then the whole system will collapse, and it sends the signal to the PCM, causing the illumination of the error codes. 

How to Fix the OBD Error Code P000A?

Troubleshooting the error code P000A is an extensive process that is encountered with various fixations of the parts in the camshaft. We will describe a step-by-step guideline to troubleshoot the error code P000A.  

  • Check the camshaft position sensor 

The sensor is the most significant part of the camshaft, and you should know that the sensor has three-wire sensors: the reference, signal, and ground sensor. An immense possibility requires that one 0of the sensors may be hampered and stop working. You need to introduce a digital multimeter (DMM) to check the voltage position of the wire sensors. If the multimeter gives actual data, you no longer have to worry about the sensors and move to the next section.  

  • The oil control solenoid and solenoid circuit

The oil control solenoid is the core section that operates the circulation of oil into the upper sectioned camshaft of the engine. Before initiating the repairing work, you need to remove the solenoid connector and introduce a multimeter to determine the voltage in the oil control solenoid. After you are done repairing the solenoid, you need to give focus on the solenoid circuit, and the ground terminal initiates the harness at one side of the connector. The standard voltage metering fluctuates around 10 volts, and if the rating fluctuates too much, then you need a repair bin for the circuit. 

Recover timing chain

If everything passes the diagnosis you gave, check the timing chain. Sometimes the gears and the tooth of the chain dislocate, replacing that missing tooth to give a smooth circulation of the timing chain.

Wrapping Up

Due to a variety of causes, the error code may illuminate in the CELL. The diagnosis and repair need to go through a tiresome process. It’s more than a DIY job; it is wise to consult a professional to combat the error code P000A. A set of high-end tools and an advanced OBD-II scanning tool are needed. As mentioned in the article, there are a bunch of parts that can be affected due to the error code P000A. So considering that extensiveness, this article can be proven to be a logical and helpful suggestion to overcome the fault code. I hope you will be benefited from this article; if you do so, share the pieces of knowledge with others so that they can combat the fault code P000A with ease.
