I HAVE p0010 code Problem.CAMSHAFT POSITION ACTUATOR CIRCUIT


P0010 - "A" Camshaft Position Actuator Circuit (Bank 1)

A P0010 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0010 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine).

Symptoms may include:
* Check Engine Light illuminated (Malfunction Indicator Lamp)
* Rough running
* other symptoms may also be present

Causes: A code P0010 may mean that one or more of the following has happened:
* Faulty oil control valve (OCV)
* Open or short in the VVT/VCT circuit
* Open or short in the OCV / solenoid valve
* Damaged computer (PCM)

Possible Solutions: Some recommended troubleshooting and repair steps are:
* Carefully inspect the Bank 1 VVT/VCT system circuit wiring and connectors, repair as required
* With a warm engine, test the operation of the OCV, replace/repair as needed


Hope this helps to solve it (remember to rate this answer).

VOLVO S40 VVT VALVE


Very easy to swap the vvt valve,but that will not guarantee to rectify the problem,more than likely it will be the vvt pulley/timing unit,this will involve the timing belt coming off.
The vvt valve is located under the upper timing cover,remove the cover and you will see the valve situated on top of the head,undo the connector and remove the 4 bolts and the valve will come off,alittle bit of oil will come out on removal.
remove gasket and ensure the area is clean.
Re-fitting is opposite procedure,ensure a new gasket is fitted.
Hope this helps
