Camshaft Timing Chevrolet Spark B12 - Spark Chevrolet Cars & Trucks

Under normal conditions, the camshaft sensor contributes to the efficient timing/firing of coil plugs and fuel injectors.

The meaning of p0013

THESE ARE THE TOOLS U NEED TO HAVE AND PROCEDURE!!GOOD LUCK AND BEWARE THE TIMING..REPLACE BOTH CHAIN AND TENTIONER!!!!!!



















Special tools and workshop equipment required
t Dial gauge -VAS 6079-
t Puller -T10094 A-
t Dial gauge adapter -T10170-
t Camshaft clamp -T10171-
t Counterhold tool -T10172-
t Locking pin -T40011-
t Spark plug spanner -3122 B-
t Counterhold tool -3415-
t Torque wrench (5...50 Nm) -V.A.G 1331-
Procedure
- Remove valve timing housing > Chapter.
- To turn crankshaft, reinstall bearing bush, crankshaft pulley -2- and crankshaft bolt -3- and securely tighten crankshaft bolt (use counterhold 3415).
- Remove spark plug from No. 1 cylinder. Use puller -T10094 A- and spark plug wrench 3122 B.
- Screw dial gauge adapter -T10170- into spark plug hole to stop.
- Screw dial gauge -VAS 6079- and extension -T10170/1- in to stop and lock in position with lock nut -arrow-.
- Turn crankshaft in direction of engine rotation, to TDC No. 1 cylinder. Note position of small needle on dial gauge.
- Then turn crankshaft back 45° opposite direction of engine rotation.
- Press tensioning guide rail -1- in direction of arrow and lock piston with locking pin -T40011-.
- Mark direction of rotation of timing chain -3- using felt-tip marker.
- Remove bolts -2- and remove camshaft sprocket -1- with timing chain -3-. Counterhold using counterhold tool -T10172-.
- Renew bolts -2-. Tighten bolt -2- to 50 Nm (use counterhold -T10172-).
- Turn inlet and exhaust camshafts until camshaft clamp -T10171- can be pushed into holes in camshaft to stop.
Locking pins -arrows 1- must engage in holes -arrows 2-. Inscription "TOP"-arrow 3- must be readable from above.
Note
Camshafts must not be pushed axially whilst turning.
- Install a M6 bolt -arrow- hand-tight (do not tighten) to secure camshaft clamp -T10171-.
- Remove camshaft sprocket bolts. It is absolutely necessary to use counterhold tool -T10172- for this.
Note
Camshaft clamp -T10171- must not be used as a counterhold tool.
- Remove one camshaft sprocket.
- Place timing chain over camshaft sprockets, observing chain direction of rotation, and install camshaft sprocket again.
- Tighten camshaft bolts until camshaft sprockets can still just be turned on camshafts.
- Tension timing chain by removing locking pin -T40011-.
- Turn crankshaft in engine direction of rotation to TDC No. 1 cylinder. Permissible deviation from TDC No. 1 cylinder: ±0.01 mm.
Note
If crankshaft is turned more than 0.01 mm past TDC, then turn crankshaft back 45° against engine direction of rotation. Then turn crankshaft in direction of engine rotation to TDC No. 1 cylinder.
- Hold camshaft sprockets -1- and -4- in this position with counterhold -T10172- then tighten bolts -2- to 50 Nm.
Note
Crankshaft must not move and timing chain -3- must remain tensioned on both sides when tightening camshaft bolts.
- Remove camshaft clamp -T10171-.
- Turn crankshaft two rotations in direction of engine rotation to TDC No. 1 cylinder. Permissible deviation from TDC No. 1 cylinder: ±0.01 mm.
- Insert camshaft clamp -T10171- to stop in camshaft openings.
If camshaft clamp -T10171- cannot be fitted
- Repeat adjustment.
If camshaft clamp -T10171- can be fitted
- Remove camshaft clamp -T10171-, hold camshaft sprockets with counterhold tool -T10172- and tighten bolts -2- a 1/4 turn (90°) further with a rigid wrench.
Note
Camshaft sprockets must not move on camshaft whilst tightening.
- Turn crankshaft two rotations again, in engine direction of rotation, to TDC No. 1 cylinder. Permissible deviation from TDC No. 1 cylinder: ±0.01 mm.
- Insert camshaft clamp -T10171- to stop in camshaft openings.
If camshaft clamp -T10171- cannot be fitted
- Repeat adjustment.
Further assembly is basically the reverse of the dismantling procedure. In the process, note the following:
t Installing valve timing housing > Chapter.
t Installing poly V-belt > Chapter.
t Renew oil seals for camshaft sealing cover and oil them before fitting.

probably forgot to reinstall camshaft sensor which located on timing cover or forgot to reconnect camshaft sensor because crankshaft sensor and camshaft sensor work together to control fuel timing and spark timing.make sure ignition coil getting 12 volts.

Possible you broke a camshaft or one of the cam gears is not connected to the camshaft ?
Can you watch the starter turn the cam via the timing belt ?

check for a vacuum leak

Thanks for choosing FixYa and welcome. Check your timing belt/chain first. Check all of your fuses also, just in case. The camshaft is a possible cause to your issue. The signal may not be getting back to the computer. In order to find the issue, you will need to get a voltage meter to test the parts of the ignition system. Make sure the spark is a good spark, as well as the fuel pressure.

If you have no spark, and you replaced the Crankshaft Position sensor, you may have a faulty Camshaft Position sensor, failed Timing Chain or stretched Timing Chain, or a faulty ECM. Since the Camshaft Position sensor doesn't cost much, I would start with that after checking the Timing.
Also, be sure to check the condition of the Connector going to the Crankshaft Position sensor and Camshaft Position sensor.
