SOURCE: 2007 Tucson, has poor idle

When diagnosing the Continuously Variable Valve Timing (CVVT) system for rough

idling, poor acceleration, camshaft timing misalignment-related trouble codes, misfire related

trouble codes, and/or other related symptoms, it may be required to inspect the
Oil Control Valve (OCV) for proper operation.

Diagnostic Trouble Codes (DTC):
P0016 = Crankshaft position-Camshaft position correlation (Bank1 Sensor A)
P0300 = Random / Multiple cylinder misfire detected

Follow the procedure to inspect the OCV. If the OCV operates normally, then carry out other necessary repairs. Do not replace the OCV if normal operation is confirmed.

INSPECTION FLOW DIAGRAM:

OCV COIL RESISTANCE SPECIFICATION:

OCV SUPPLIER : COIL RESISTANCE AT 68°F (20°C)

Denso 6.9~7.9 Ohms
Delphi 6.7~7.7 Ohms

OCV INSPECTION PROCEDURE:
1. Measure the resistance between the OCV Power and Signal terminals.

tdisline_3.jpg

MEASURED RESISTANCE 68°F (20°C). RECOMMENDED ACTION

1.1. Denso (6.9~7.9 Ohms)

1.2. Delphi (6.7~7.7 Ohms)

Check if the OCV operates normally by providing 12V power. (See the STEP 2.)

1.2. Infinity (OPEN): Open circuit - Replace the OCV.
1.3. Below specified range or zero: Short circuit - Replace the OCV.

2. Check if the OCV operates normally by providing 12V power as shown in the picture
below.

tdisline_4.jpg

IMPORTANT: Careful attention is necessary to avoid a short circuit when providing the OCV with 12V power. Spacing between the OCV power and signal terminals is very narrow. Use suitable connections to prevent shorting of the test power supply.


3. When 12V power is provided to the OCV, the OCV must move forward as shown in the picture below.


A: Maximum retarded valve timing condition (12V not provided)

B: Maximum advanced valve timing condition (12V provided)


NOTE: Reverse the connection polarity if the movement is opposite.


tdisline_5.jpg

4. If the OCV does not move forward, examine if a foreign object like an aluminum chip (C) is jammed inside the OCV.


• Blow out the foreign object using compressed air, reinstall the OCV and then verify that the fault is corrected.

• If there is no damage to the OCV, then do not replace the OCV.

P0300 - Random/Multiple Cylinder Misfire Detected
Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.

A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present

Causes: A code P0300 may mean that one or more of the following has happened:
* Faulty spark plugs or wires
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector(s)
* Burned exhaust valve
* Faulty catalytic converter(s)
* Stuck/blocked EGR valve / passages
* Faulty camshaft position sensor
* Defective computer

Possible Solutions

If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Try this same solutionsa for each case, keep in mind that P0302 is missfire for #2 cyl, P0305 is misfire for #5 cyl and more.

Hope this helps (remember to rate this answer).

SOURCE: repeated code P0301 and P0302

you don`t if say if you know but these codes mean misfire on cylinder 1 and cylinder 2.you also don`t say if you tried anything to fix.check out plugs they may need changing,it could be bad ignition wires or dirty injectors,or even dirty valves(not closing completly)causing misfire.you could have low compression on these two cylinders also.

Each one of the codes indicate misfire, except p0320.

1. Check IG failure sensor (1) Connect IG failure sensor and PCM connector (2) Engine "ON" (3) Check that RPM meter on instrument panel is operating correctly and the signal waveform of IG failure sensor at terminal 4.

If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair" procedure. NO ??¶ Substitute with a known - good IG failure sensor and check for proper operation. If the problem
