P0024 – Meaning, Causes, Symptoms, & Fixes

P0024
TABLE OF CONTENTS

What Does Code P0024 Mean?

  • P0024 definition: Exhaust Camshaft Timing- Over-Advanced Bank 2
  • Issue Severity: SERIOUS – Stop driving immediately.
  • Repair Urgency: Fix this code immediately to prevent serious engine damage.
  • Diagnosis: This trouble code severely impacts the drivability of your vehicle. The most common problems consist of increased engine stalling, rough engine idle, lowered fuel economy, and rattling/knocking noises from the engine. Continuing to drive the vehicle in this condition can cause severe damage to multiple internal engine components.

The variable valve timing system increases fuel economy and engine performance by regulating when the intake and exhaust valves are opened and closed. The camshaft(s) is(are) adjusted by the ECM through the use of an oil control valve(s) (OCV) also called variable valve timing control solenoid valves. When trouble code P0024 is set, it means that the exhaust camshaft in Bank 2 is more advanced than the ECM has told it to be.

P0024 Causes

  • Engine oil is dirty
  • Engine oil is too low
  • Engine oil is incorrect viscosity
  • Camshaft variable timing solenoid failure
  • Camshaft phaser is seized in the advanced position
  • Continuous oil flow to Variable Camshaft Timing chamber

P0024 Symptoms

  • Check Engine Light
  • The hard start of the engine
  • Rough running engine
  • Stalling
  • Rattling/Knocking from engine
  • Decreased fuel economy
  • Failed emissions test

How Do I Fix Code P0024?

With a P0024 code, the first step is to get it properly diagnosed to figure out what is causing the issue with the camshaft timing. Using the live data function of the FIXD sensor and app allows you to read and analyze engine data to properly diagnose a P0024 code.

If the sensors are all reading correctly and you’re not comfortable further diagnosing this issue at home, we recommend finding a RepairPal-certified shop to pinpoint the problem and give an accurate estimate for repairs.

These shops can not only help you figure out what’s going wrong before you waste time and money on the wrong parts, but they also offer a minimum 12-month, 12,000-mile warranty and stand behind all their estimates with guaranteed fair pricing.

How Much Does It Cost to Fix Code P0024?

If you take your car to a shop for diagnosis, most shops will start with an hour of “diag time” (the time spent in labor diagnosing your specific issue). Depending on the shop’s labor rate, this typically costs somewhere between $75-$150. Many, if not most, shops will apply this diagnosis fee to any required repairs if you have them perform the repairs for you. From there, a shop will be able to give you an accurate estimate for repairs to fix your P0024 code.

Possible Repair Costs for P0024

When it comes to making repairs associated with the P0024 code, one or more of the below repairs may be needed to solve the underlying issue. For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair.

  • Oil Change $20-$60
  • Oil Control Valve/Variable Valve Timing Control Solenoid $300-$400
  • Engine $3000-$4000

DIY Steps to Diagnose Code P0024

If you’d like to try to fix code P0024 at home without throwing money at parts, you’ll want to follow the steps below for proper diagnosis. Complete diagnosis may require some specialized equipment beyond what the FIXD Sensor can provide, but for the most part, this diagnosis and repair can be attempted by beginner DIYers.

DIY difficulty level: Expert

This repair should not be attempted by beginner DIYers.

Tools/parts needed (our top picks from Amazon):

  • FIXD
  • Basic hand tools
  • Fused jumper wires
  • Vehicle specific service manual

STEP 1: USE FIXD TO ENSURE NO OTHER ENGINE CODES ARE PRESENT.

Scan your vehicle to verify P0024 is the only code present. If other codes are present, they must be addressed first.

STEP 2: CHECK FOR OIL SLUDGE.

Check the engine oil level and condition. If it’s low, adjust to spec and test drive to see if the concern is resolved. If it’s dirty, change the oil and filter and test drive to see if the concern is resolved. Remove the oil cap and/or the valve cover and inspect the valve train for sludge. If there is sludge, there is a good chance the engine will need to be replaced due to sludge blocking the oil passages to the Oil Control Valve(s)

STEP 3: CHECK OIL CONTROL VALVE.

If there isn’t any sludge, consider checking the Bank 2 Intake Camshaft Oil Control Valve for proper function. You can do this by removing the Oil Control valve and supplying power and ground to the solenoid quickly using a pair of fused jumper wires. (Do not leave power applied for more than a second or two) If the valve is functioning properly it should click, and you may even be able to see the valve move based on the design of your specific valve. If it doesn’t click or move, replace the tested oil control valve and test drive to see if the concern is resolved.

STEP 5: CONSULT A PROFESSIONAL.

If at this point the vehicle is still setting the same code, you may have a more serious problem with your car’s oxygen sensor system, and you should bring the vehicle to a certified shop to have further diagnostic work performed.

Common P0024 Diagnosis Mistakes

Replacing sensors or components without any indication of a problem with the sensors or components.
