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 control timing solenoid valves. The P0022 code is set when the ECM detects the camshaft timing for the intake camshaft on bank 2 is more retarded than what it has been set to be.

P0022 Causes

  • Engine oil too low*
  • Dirty engine oil*
  • Sludged up engine
  • Low oil pressure
  • Malfunctioning camshaft timing
  • Short in intake timing control/oil control circuit
  • Faulty intake valve timing control solenoid
  • Faulty oil control valve (OCV)

P0022 Symptoms

  • Check Engine Light
  • Rough engine performance
  • Other codes such as misfire codes (P0300-P0308)
  • Rattling/Knocking from engine
  • Stalling
  • Lowered fuel economy

How Do I Fix Code P0022?

With a P0022 code, the first step is to get it properly diagnosed to figure out what is causing the malfunction related to the camshaft position. Using the live data function of the FIXD sensor and app allows you to read and analyze engine data to properly diagnose a P0022 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 P0022?

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 P0022 code.

DIY Steps to Diagnose Code P0022

If you’d like to try to fix code P0022 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: Beginner

This repair can be attempted by beginner DIYers.

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

  • FIXD
  • Basic hand tools
  • Engine oil pressure gauge
  • Fused jumper wire
STEP 1: USE FIXD TO ENSURE NO OTHER ENGINE CODES ARE PRESENT.

Scan your vehicle to verify P0022 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 4: 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 P0022 diagnosis mistakes

Prematurely replacing any component when the issue can be resolved by changing the oil and filter and adjusting the oil level to the correct level per your vehicle’s manufacturers specifications.

    1. Hi I have the same problem !! Do you found the problem yet ?

    2. Take off the valve cover gasket check if your timing chain is in good condition and in time

  2. I have a 2012 Lincoln MKZ and also have a POO22 code. The oil was clean but I changed the oil/filter and got the code again after about 200 miles. My is bank 2 and from what I’ve read the sensor is located in the front cylinder head on the drivers side. I plan on replacing it and see what happens.

  3. Just put on a brand new cam and timing chain and a complete tune up and and a brand new exhaust systemstill have this issue. Not happy at all. It’s on a 2008 Mercury mountaineer

  4. I have a question.my code indicates that I have an issue at bank 2 how do I know which I bank #2?
