How is fault code P0024 fixed?

A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Check the oil level and condition before anything else. If it's low, black, sludgy or the wrong grade, top it up or do an oil and filter change and clear the code, then see if it comes back 2. Read all stored codes and the freeze frame. Codes like P0021, P0022, P0014 or P0017 alongside it point you towards bank 2 timing and help confirm the picture 3. Look at live camshaft position data at idle and on a road test. A cam that won't settle on its commanded angle tells you whether the phaser is actually being controlled 4. Pull the bank 2 VVT solenoid and inspect it. Test the resistance, commonly in the 7 to 12 ohm range, and check the screen and plunger aren't gummed up with varnish 5. Inspect the wiring and connector to the solenoid and the bank 2 cam sensor for corrosion, chafing or oil contamination 6. If oil, solenoid and wiring all check out, you're looking at the chain or phaser. Compare cam and crank correlation and check timing marks line up before condemning anything mechanical

What does it mean?

In most cases if P0024 comes up it is due to lack of oil lubrication. The best way to rectify the situation is to apply an engine cleaning product and do an engine rinse before re-installing a new VCT/VVT solenoid. If that is not done you will have near future failure of the new VCT/VVT solenoid. It is very important to note in the new VCT/VVT engines they are very susceptible to lower cost oils. You need to purchase high end oils in order to have a longer lasting camshaft oil timing system.

You definitely get what you pay for in this case. VVT- Variable Valve Timing VCT- Variable Camshaft timing You have an intake camshaft solenoid error usually. Not manufacturer specific, is a generic code. Bank B or bank 2 if a 4 cylinder engine. Depending on the type of engine if you have two banks then will have a bank 1 error. Then go into a P0014 code situation. Exhaust side
