What are the probable causes of camshaft sensor DTC?


Camshaft sensors do go bad. They can go bad slowly, so you don't notice the badness until your engine stalls, but restarts, or you get a "check engine" light. They are not expensive or hard to replace.

4jx1 camshaft marks on isuzu trooper 2001 3,0 dohc engine


the timming gear that the belt runs on has a mark (V cut in gear) to rear cover at about 12 o clock and crank pulley has timming mark for top dead centre, both cams have cut outs in rear that a special tool (camshaft stopper 5-8840-2592-0) locks into to hold cams in correct position, but can do without this, if the cam belt gear is off, the keyway should be at 12 o clock. the marks in the camshaft gears (dots) is for assembly of sissor gears to solid gears on camshafts that run together and they should match up only if you had this appart.

Need directions on how to install a timing chain on a 2002 Saturn L series 2.2 liter along with the allignment marks for the intake and exhaust cams


To Install:
  1. Install or connect the following:
    • Timing chain drive sprocket to crankshaft
      1. Rotate the crank so the mark on the sprocket is at the 5 o'clock position
  2. Assemble chain to the intake camshaft sprocket alignment copper link to the "INT" diamond timing mark on the camshaft sprocket sat_car_22_tmng-chn_pos.gif

    NOTE: When lowering the timing chain rotate the assembly 90° to allow the chain to fall between the cylinder block bosses then rotate the assembly back so the camshaft sprocket is facing forward.
    sat_car_22_tmng-c_hsng_opng.gif

  3. Lower the assembly through the chain housing opening on top of the cylinder head. Use care to ensure that the chain goes around both sides of the cylinder block bosses NOTE: The crankshaft sprocket timing mark will be at approximately the 5 o'clock position.
  4. Route chain around crankshaft sprocket and align silver link to the timing mark sat_car_22_set_tdc.gif

    NOTE: The camshaft sprocket bolts are not reusable; they are torque-to-yield and must be discarded to prevent premature failure.
  5. Install or connect the following:
    • Intake camshaft sprocket loosely onto the intake camshaft then install the new camshaft sprocket bolt finger tight NOTE: It is not necessary to align the sprocket-to-camshaft offset notch at this time.
    • Adjustable timing chain guide through the opening on top of the cylinder head then install the chain guide bolt; torque to 89 lb-in. (10 Nm) sat_car_22_ajst_tmng-ch_guid.gif

      sat_car_22_cm-shft_sprkt_blts.gif

    • Exhaust camshaft sprocket loosely onto the exhaust camshaft with the timing mark on the sprocket aligned with the silver link then install a new camshaft sprocket bolt finger tight
    NOTE: It is not necessary to align the sprocket-to-camshaft offset notch at this time.
    NOTE: The camshaft sprocket bolts are not reusable; they are torque-to-yield and must be discarded to prevent premature failure.
  6. Align the camshaft sprocket-to-camshaft then tighten the camshaft bolt using the following procedure: sat_car_22_crnk_tmng-c_mrk.gif

    NOTE: Do not rotate either camshaft more than 1/2 turn in either direction with the crankshaft at Top Dead Center (TDC). To do so may cause valve to piston contact resulting in a damaged valve and/or a damaged piston.
    • Ensure that the sprocket timing mark is at the 5 o'clock position
    • Rotate the intake camshaft using a 24mm wrench on the flats of the camshaft until the sprocket-to-camshaft alignment notch seats
    • When the sprocket seats on the camshaft tighten the sprocket bolt finger tight
    • Rotate exhaust camshaft using a 24mm wrench on the flats of the camshaft until the sprocket-to-camshaft alignment notch seats
    • When the sprocket seats on the camshaft tighten the sprocket bolt finger tight
  7. Verify that all colored links are aligned with the appropriate marks on the camshaft and crankshaft sprockets NOTE: If they are not repeat steps 1C through 4.
  8. Install the fixed timing chain guide and bolts; torque to 89 lb-in. (10 Nm)
  9. Install the fixed timing chain guide bolt access hole plug; torque to 30 lb-ft. (40 Nm)
  10. Install upper timing chain guide and bolts; torque to 89 lb-in. (10 Nm) NOTE: Use a 24mm wrench to support the camshaft while applying torque to the camshaft sprocket bolt. Do not torque the camshaft bolts against the timing chain as it may damage the timing chain.
  11. Torque the intake and exhaust camshaft sprocket bolts; torque as follows:
    • First Pass: 63 lb-ft. (85 Nm)
    • Second Pass: Turn an additional 30° using a torque angle gauge
  12. Install the sealing ring and tensioner assembly; torque to 55 lb-ft. (75 Nm)
  13. Install or connect the following:
    • Timing chain oil nozzle and bolt; torque to 89 lb-in. (10 Nm)
    • Camshaft cover assembly
    • Engine front cover
    • Negative battery cable; torque to 13 lb-ft. (17 Nm)

Where r the glow plugs on a isuzu 4jx1 engine


The glow plugs are in the cylinder head. Remove the plastic cover which hides the camshaft cover, and find the black wire that connects to the common bus which connects all four glow plugs. They should be easy to see once you have the cover off.
