2007 Cadillac 3.6L srx, check engi, code p00017 crank sensor - replaced, still running rough and giving me a misfire on 1,3&5. Changed plugs, still 1,3&5 misfire - 155000 miles, could it need new coil


P0017 timing chain Chevy Colorado P0017 Case Study Part 1
155,000 miles This is not a DTC for the crank sensor . This is for variable valve timing .
DTC P0017: Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation Bank 1
The camshaft position (CMP) actuator system enables the engine control module (ECM) to change the timing of the camshafts while the engine is operating. The CMP actuator solenoid signal from the ECM is pulse width modulated (PWM). The ECM controls the CMP actuator solenoid duty cycle by controlling the amount of solenoid ON time. The CMP actuator solenoid controls the advance or the retard of each camshaft. The CMP actuator solenoid controls the oil flow that applies the pressure to advance or retard the camshafts.
Ignition voltage is supplied directly to the CMP actuator solenoid. The ECM controls the solenoid by grounding the control circuit with a solid state device called a driver. The ECM compares the camshaft position or the camshaft angle, to the position of the crankshaft.

Your a little out of your league on this ! Your best bet ,take it to a qualified repair shop !

• Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, camshaft sensor, crankshaft sensor, or timing chain can cause this DTC to set.
• An actuator that is in the full advance or retard position can cause this DTC to set.
• The presence of DTCs P0008 and P0009 along with P0016, P0017, P0018, and P0019 indicates a possible condition with the primary timing chain and the alignment between both intermediate sprockets and the crankshaft. Or, the crankshaft reluctor wheel has moved and is no longer referenced to top dead center (TDC).
• Observing the desired and actual camshaft angle parameters, with a scan tool before a DTC sets, may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

Getting p0016 code


Crankshaft Position - Camshaft Position Correlation
What does this mean? OBD Code P0016refers to
The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position. The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together. If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 code will set.
Symptoms Possible sumptoms of OBD code P0016
Malfunction Indicator Lamp (MIL) illumination The engine may run but with reduced performance The engine may crank but not start The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged The engine may start and run, but poorly
Causes Possible causes of OBD code P0016
Timing chain stretched, or timing belt skipped a tooth due to wear Misalignment of timing belt/chain Tone ring on crankshaft slipped/broken Tone ring on camshaft slipped/broken Bad crank sensor Bad cam sensor Damaged wiring to crank/cam sensor Timing belt/chain tensioner damaged
Possible Solutions First, visually inspect the cam and crank sensors and their harnesses for damage. If you notice broken/frayed wires, repair and recheck. If you have access to a scope, check the cam and crank patterns. If a pattern is missing, suspect a bad sensor or a slipping tone ring. Remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings for proper alignment and make sure they're not loose or damaged or that they haven't sheared the key that aligns them. If they are properly installed, replace the sensor. If the signal appears normal, then check the timing chain/belt for proper alignment. If it's misaligned, check for a damaged tensioner that may have allowed the chain/belt to slip a tooth or several teeth. Also check that the belt/chain isn't stretched. Repair and recheck.

How do i set camshafts on 1999 duvil northstar


Remove camshaft covrs
Remove front cover
Remove or fully retract all three timing chain tensioners
Remove oil pump
Primary and secondary chain guides should remain in place. Rotate crankshaft until sprocket drive key is at about 1 o'clock position.
Set crankshaft and intermediate shaft sprockets into primary drive chain with their timing marks asjacent to each other.
Install crankshaft and intermediate sprockets over their respective shafts. Rotating crankshaft as necessary to engage crankshaft key in sprocket without changing the timing mark relationship.
Install Flywheel Holder Tool (J-39411) to lock crankshaft in position. Install intermediate shaft sprocket retaining bolt and torque to specifications.
Route secondary chain for left cylinder head over inner row of intermediate shaft teeth.
Route secondary drive chain over chain guide, and install exhaust cam sprocket to chain so camshaft drive pin engages the sprocket notch marked "LE" (Left Exhaust).
There dhould be no slack in the lower section of the chain, and the camshaft drive pin must be perpendicular (90 degrees) to the cylinder head surface.
Install the intake camshaft sprocket into the chain so the sprocket notch marked "LI" (Left Intake) engages camshaft drive pin, while drive pin remains perpendicular to the head face. Minor adjustments can be made to camshaft position to get pin to engage by using a wrench on the hex cast into the camshaft.
Install sprocket retainer bolts and torque to specification.
Repet steps as above to install the right secondary chain to the right camshafts. The right camshaft sprockets are marked "RE" and "RI". In addition, the RE sprocket must contain the camshaft position sensor pickup.

Am having trouble on finding the marks to re place the timing chain on a ford expidition 99


The timing chain on a Ford Expedition works with the camshaft and crankshaft, turning them through sprockets. The alignment with the chain and its sprockets is very precise, so replacing the chain is a very precise and difficult procedure. The chain has its own cover that you must remove to access it. Consult your mechanic before working on the timing chain. The process can vary depending on the year and engine type. Professional maintenance is always recommended.
  1. Removing the Chain Cover
    • 1 Disable the truck's ignition system by disconnecting the primary electrical connectors at the ignition coil pack. Disconnect the negative battery cable before you do this.
    • 2 Take out the spark plugs by unplugging their wires and removing them with a socket wrench and spark plug socket.
    • 3 Install a compression gauge into the Number One cylinder and use a breaker bar and socket on the crankshaft's damper bolt to turn the crankshaft. Turn it until the notch in the damper aligns with the TDC mark on the front cover and compression is noted on the gauge.
    • 4 Drain the engine oil from the truck into a pan by removing the oil pan plug and remove the oil filter with a filter wrench.
    • 5 Unbolt and remove the crankshaft pulley and vibration damper; mark their positions so they can be installed the same way. Avoid turning the crankshaft as you remove the damper.
    • 6 Remove all accessory brackets connected to the timing chain cover by unbolting them. This includes unbolting the power steering pump; set it aside with its hoses still connected.
    • 7 Disconnect the camshaft position sensor's electrical connector and remove the camshaft position sensor. Disconnect the electrical connectors for the crankshaft position sensor and knock sensor.
    • 8 Remove the front bolts on the oil pan and the socket-head bolt--the latter requires an Allen wrench. Disconnect the heater hoses and then unbolt and pull out the heater outlet tube.
    • 9 Separate the timing chain cover by removing its bolts. You may need to tap it with a soft face hammer if it's stuck.
    Changing the Chain
    • 1 Check and see that the timing marks on the camshaft, crankshaft and balance shaft sprockets are all aligned. If not, re-install the vibration damper bolt so you can turn the crankshaft clockwise to align the marks.
    • 2 Remove the camshaft sprocket's mounting bolt and the camshaft position sensor's drive gear. Compress the timing chain tensioner with a screwdriver, hold the tensioner in the retracted position with a drill or Allen wrench and pull the sprocketed chain off the camshaft.
    • 3 Turn the camshaft until the key is facing the 12 o'clock position (straight up).
    • 4 Place the replacement chain on the camshaft sprocket, turn the sprocket until its timing mark faces 6 o'clock (straight down), position the chain over both sprockets with their timing marks lined up and slip the sprockets on the camshaft and crankshaft.
    • 5 Install the camshaft position sensor drive gear by aligning its keyway arrow with the Woodruff key on the camshaft.
    • 6 Install the camshaft sprocket bolt, applying a non-hardening thread-locking compound to the threads, and tighten the bolt to 30 to 36 foot-pounds.
    • 7 Remove the drill or wrench from the timing chain tensioner and re-install all the other parts in the reverse order of removal. This includes adding fresh engine oil and a new oil filter.

a) Place the check ball end of tensioner into the shallow end of Special Tool 8186.
b) Using hand pressure, slowly depress tensioner until oil is purged from tensioner.
13. Reset timing chain tensioner using the following procedure:
a) Position cylinder plunger into the deeper end of Special Tool 8186.
b) Apply a downward force until tensioner is reset. NOTE: If oil was not first purged from the tensioner, use slight finger pressure to assist the center arm pin of Special Tool 8186 to unseat the tensioner's check ball. CAUTION: Ensure the tensioner is properly reset. The tensioner body must bottom against the top edge of Special Tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.
14. Install the reset chain tensioner into the right cylinder head.
15. Position tensioner retaining plate and tighten bolts to 12 Nm (105 in. lbs.).
16. Starting at the right cylinder bank, insert a 3/8" square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and tighten to 28 Nm (250 in. lbs.).
17. Turn the left side camshaft by inserting a 3/8" square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed. Tighten sprocket bolts to 28 Nm (250 in. lbs.).
18. Rotate engine slightly clockwise to remove timing chain slack, if necessary.
19. To arm the timing chain tensioner: Use a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner is armed (extends).
20. Install the timing chain cover, crankshaft damper, and cylinder head covers.
21. Install camshaft position sensor and connect electrical connector.

Hope this helps!
