P0024 OBD Error Code: Problem & Solutions

<<See All OBD Codes

If you notice that the camshaft timing is over advanced, Control Valve to the bank 2 camshaft is stuck closed, the oil is too thick or the camshaft phaser is getting stuck in the advanced position, then there are chances that you are dealing with the OBD Code P0024 with your vehicle.

If the camshaft timing for engine bank 2 is advanced beyond the predetermined limit, then this code would start indicating. The “B” here identifies the exhaust camshaft which is situated to the exhaust side of the cylinder head. The “Bank2” refers to the engine bank which has the number two cylinder.

What causes this problem with the Camshaft Position - Timing Over-Advanced or System Performance?

• The ECM may detect that the camshaft timing is over advanced by using the camshaft and crankshaft sensors
• The Oil Control Valve to the bank 2 camshaft may be stuck closed or can have clogged passages
• The oil may be too thick and due to this the passages would become clogged because of lack of oil flow to or from the camshaft phasers that control the timing
• The camshaft phaser may get stuck in the advanced position

1. Electromagnetic Sensors - The P0024 code can also arise due to some issues in Electromagnetic Sensors. So, it is advised to replace them as soon as possible.
2. Crankshaft - P0024 code does not really end up spoiling your engine control module, but it might also accompany few Crankshaft issues. We have best Crankshaft related parts with us.
3. Powertrain Control Module - The P0024 code can also arise due to some issues in Powertrain Control Module. So, it is advised to replace them as soon as possible.
4. Camshaft Sensor - Common cause behind this P0024 error code can be some fault in Camshaft Sensor. So, it will be a good decision to replace them now.
5. Digital Volt/Ohmmeter - Willing to buy Digital Volt/Ohmmeter? You can always visit us to purchase them at equitable prices.

Some common symptoms of P0024 fault code may include roughness when accelerating with decreased fuel economy. The code would be stored in the PCM and malfunction indicator lamp would start illuminating.

Common Symptoms

• An illumination in the check engine light and the engine is put in failsafe mode
• A hard start condition would be faced by the car engine
• The engine may start running roughly, hesitating or stalling
• A pre-ignition problem on acceleration may be faced by the engine
• The engine's emissions can start exceeding federal levels and can fail an emissions test

• A visual inspection should be performed to determine any electrical connector, wiring or valve issues of the camshaft oil control valve for the bank 2 exhaust camshaft
• Make sure that your car engine is full of clean engine oil with the correct viscosity
• View the freeze frame data to check when the code was set
• Then you must reset as well as clear the OBD-II fault codes and then later you can retest the vehicle to check if the P0024 code comes back
• The manufacturer's specific pinpoint test should be performed

• Electromagnetic sensors are used to monitor Crankshaft and camshaft positions
• The relief holes in camshaft and crankshaft drive gears are utilized by these sensors to provide signal interruption of the electromagnetic field
• The PCM sees the interruptions in the electromagnetic field as square waveform patterns, which represent varying degrees of voltage
• Electromagnetic resistance creates these variations in voltage in the 5-volt circuit.
• Some manufacturers use multiple crankshaft sensors to feed separate data streams to the PCM
• These data streams provide input for engine ignition as well as fuel injection timing
• A camshaft sensor is generally used by the engines that are equipped with multiple camshafts
• Notches cut into shafts or nodules are used by other automakers that are permanently attached to interrupt the electromagnetic field
• The notches or nodules are located near the rear or middle of the shaft and it all depends upon sensor placement.
• The crankshaft sensor can be placed on top of the transmission bell-housing and crankshaft position from interrupter holes in the flex plate is read
• You must start proper diagnosis by making sure that all engine timing indicators are properly aligned
• After making sure that timing marks are aligned, test belt or chain deflection using manufacturer’s specifications.
• VVT or VCT solenoids and circuitry should be carefully inspected if timing components prove to be properly aligned as well as in proper working order.
• PCM and sensor failure are generally rare
• Electrical wiring as well as connectors are more prone to fail than sensors, especially where oil or other corrosive fluids are present. Several tools will be instrumental in successfully diagnosing this fault code
• A suitable OBD-II scanner, a digital volt/ohmmeter, and an oscilloscope will help a lot in performing a successful diagnosis
• A manufacturer’s service manual would also be required
• A visual inspection of all wiring and connectors should be done first
• Repair or replace damaged, disconnected, shorted, or corroded wiring, connectors, and other important parts if needed

Common Mistakes When Diagnosing the P0024 Code

• You must check the car engine oil to see if it is full, clean and is of the correct viscosity for the engine
• Then you must test as well as verify the failure code before any other tests are performed
• Make sure that you follow the manufacturer pinpoint test procedures carefully step by step
• Unless and until any problem is indicated, you must not replace any sensors or components
