QuestionQUESTION: I have a 2000 volvl s40. recently i had the spark plugs and ignition coils replaced. we also replaced the timing belt. the check engine light comes on and stays on now matter how many times we clear it. we get a p1014 ( CMP Sensor/CKP Sensor Signals Not Compatible )..the car runs great and we drove it 2,000 miles from new mexico to washington dc. no problems. what is causing this code? can't get past emmissions like this.
ANSWER: Cedric,
T/belt now on correctly? Was book followed to reset the VVT? Bad cam sensor, bad VVT valve, Control unit, broken wires or corrosion in contacts. If you use a scanner made to work on Volvo, it can give you more info. Most times the belt is a tooth off or the VVT was not set correctly before the belt change. There have also been quite a few bad VVT valves.

QUESTION: no the mechanic didn't use a volvo book to reset the vvt. by vvt do you mean timing belt? how do you set the vvt correctly. thanks for your help.
AnswerCedric
VVT is variable valve timing. It retards and advances the timing for smooth idle and emissions. It operates on the cam via oil pressure. Before the belt was removed the engine should be set to TDC by turing the crank to the timing marks and then 90% more, backing it up to the TDC mark. If that is not the procedure that was followed then the timing may in fact be off. At that point you need to lock the cams and procede to set the VVT.Home

Note!
The crankshaft and the camshafts must not be turned more than is stated in the method description! If the shafts are turned in any other way the valves may be damaged.
As the illustrations in this service information are used for different model years and/or models, some variation may occur. However, the essential information in the illustrations is always correct.
Preparations
Remove:
the cable from the battery negative terminal. First read Note when disconnecting and connecting the battery lead
the inlet hose between the Air Cleaner (ACL) and Throttle Body (TB) . Place it to one side.
Remove:
the brake servo vacuum hose from the terminal in the Throttle Body (TB) . Disconnect the hose by pressing the plastic ring down. At the same time pull the hose upwards. Move the hose to one side
the fuel line and wiring from the clips at the rear edge of the cylinder head.
Remove:
the screws for the cable duct
the rear cover for the camshaft
the Camshaft Position (CMP) sensor housing
the trigger wheel
the right-hand engine splash guard
the auxiliaries belt.
Removing the timing covers
Remove:
the upper timing cover
the front timing cover.
Installing the lifting beam and lifting hook
Remove the nut for the engine mounting.
Remove the metal bracket for the servo hose from the rotation protection for the auxiliaries belt.
Position lifting beam 999 5006 slightly in front of the front lifting eyelet for the engine. Use lift arm 999 5383 and lifting hook 999 5460 to lift the front edge of the engine a few mm until the engine mounting screw can be taken out.
Removing the right-hand engine mounting
Remove:
the screws for the servo holder
the engine mounting screws
the engine mounting.
Position the engine according to the marking
Remove the right front wheel.
Position the upper timing cover.
Turn the crankshaft until the markings on the crankshaft and camshaft pulley correspond. Turn the crankshaft a further 1/4 turn clockwise and then back again until the markings correspond. The markings are illustrated. Remove the upper timing cover.
Removing the timing belt
Slacken off the center screw for the belt tensioner slightly.
Hold the center screw still and turn the tensioner eccentric clockwise to the "10 o'clock" position using a 6 mm Allen key.
Remove the timing belt from the camshaft pulleys.
Removing the timing gear pulley
Timing gear pulleys with variable valve timing unit
Install camshaft adjustment tool 999 5452 at the rear of the camshafts.
Timing gear pulleys with variable valve timing units:
Remove the plug at the front edge of the variable valve timing unit (TORX 55)
Remove the center screw from the WT unit (TORX 55). Carefully pull out the timing gear pulley with the Variable Valve Timing (VVT) unit. A small amount of oil may run out. Place paper underneath.
Timing gear pulleys without variable valve timing units:
Remove the screws for the timing gear pulley. Use counterhold 999 5199
Remove the timing gear pulley
Remove tool 999 5452
Remove the screw holding the inner timing cover to the cylinder head.
Replacing the camshaft seal
Carefully press in tool 999 5651 between the sealing ring and the camshaft.
Carefully pry out the seal.
Oil the new seal.
Install the new seal for the camshaft with variable valve timing. Use drift 999 S718.
Install the new seal for the camshaft without variable valve timing. Use drift 999 S719.
Install the screw holding the inner timing cover to the cylinder head
Secure the crankshaft position
Install the adjustment tool.
Remove:
the front air baffle
the support between the cylinder block and the intake manifold
the mounting screws for the starter motor
the lower timing cover. Place the starter motor to one side.
Remove the blind cover plug and the blind cover washer
Turn the crankshaft clockwise slightly to avoid the adjustment tool being in the wrong position.
Install adjustment tool 999 5451. Ensure that the adjustment tool bottoms out against the cylinder block.
Turn the crankshaft back counter-clockwise until it stops against the drift.
Check that the marking on the crankshaft timing gear pulley corresponds with the marking on the oil pump.
Installing the camshaft timing gear pulley
Timing gear pulleys without Variable Valve Timing (VVT)
install the upper timing cover
install the timing gear pulley without variable valve timing on the camshaft. Use the two screws positioned so that the markings on the timing gear pulleys and upper timing cover correspond. Do not tighten.
Timing gear pulleys with Variable Valve Timing (VVT):
Install the timing gear pulley using the center screw on the camshaft. Ensure that the markings on the timing gear pulleys/upper timing cover correspond. Do not tighten.
Installing the timing belt
Install the timing belt on the timing gear pulleys.
Note! Adjust so that the screws in the timing gear pulley without variable valve timing do not reach the limit position in the oval holes.
Note! This adjustment is to be made with a cold engine. Suitable temperature is approximately 20°C/67°F . At higher temperatures (with the engine at operating temperature or a high outside temperature for example) the indicator is further to the right.
The illustration shows the position of the indicator at different engine temperatures.
Carefully turn the crankshaft clockwise until the timing belt is tensioned. The belt must be tensioned between the intake camshaft pulley, the idler pulley and the crankshaft
Hold the belt tensioner center screw secure. Turn the belt tensioner eccentric counter-clockwise until the tensioner indicator passes the marked position. Then turn the eccentric back so that the indicator reaches the marked position in the center of the window
Hold the eccentric securely. Tighten the center screw. Tighten to 20 Nm
Tightening the timing gear pulley
Tighten the center screw on the timing belt tensioner with variable valve timing. Tighten to 90 Nm.
Install the plug. Tighten to 35 Nm.
Install the third screw on the camshaft without variable valve timing. Tighten to 20 Nm.
Remove the adjustment tools.
Check
Press the belt to check that the indicator on the tensioner moves easily
Install the upper timing cover
Turn the crankshaft two turns. Check that the markings on the crankshaft and camshaft pulley correspond.
Note! Check that the indicator on the belt tensioner is within the marked area.
Remove the upper timing cover.
Installing timing covers
Install:
the lower timing cover
the front timing cover. Tighten to 12 Nm
