the oil pressure sensor is in the cylinder head between fuel pump and air vacuum pump, i have a universal oil pressure kit with around 30 different connectors so not not sure on thread you need off hand, this is on same oil rail as vvt so with give a good guide to oil pressure at vvt solenoid, would also deffo do adaptation reset, ie reset it when car cold then within the program will say start car leave idling until fan kicks in then take for a drive this will reset it all back to beginning of life ie factory bass settings... i have had a number of them that react like yours when first run after a t/chain change... but oil pressure is a must do
A P0015 DTC trouble code may be caused by one or more of the following: Incorrect camshaft timing Wiring problems (harness/wiring) in intake timing control valve control solenoid system Continuous oil flow to VCT piston chamber Failed timing valve control solenoid (stuck open)
The main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.
with autocom cdp+ you can see the timing, that code relates to position sensor and timing incorrect is how i would read it. also shows timing when car rev'd ie change in timing shows vvt working if no change in timing when rev;d then vvt has a issue..
did you replace the vvt sprockets and did you put a slight preload on timing chain tensioner and set timing tighten sprocket to 40nm then replace tensioner and turn engine by hand a few times then replace tensioner with special preload tool and relock cams and crank off...IMPORTANT IF CAMS DONT FALL IN TO LOCKING POSITION WHEN CRANK LOCKED OFF LOOSEN IT ALL OFF AGAIN AND RESET,, MIGHT NEED TO DO THIS A FEW TIMES UNTILL IT ALL SETTLES DOWN,,, VERY RARELY DO THESE ENGINES TIME UP THE FIRST TRY,
added point, also when i do first 40nm torque on the bolts i always tighten crank bolt first then the front exhaust cam sprocket last the inlet cam one,, as have found its possible to put timing out a tad if go the other way around by pressure the wrong side of cam chain tensioner,
added note another thing i have found is when the chain timing is out the compression is lower on 2 and 4 will be much lower than 1 and 3 as a rule or the other way around, worth a compression test, number 1 cylinder on these engine is flywheel side and not vanos side.. i just done a peugeot thp today and and took 3 go's at getting it to lock off correctly each time,, you must use the 10mm bolts to hold locking tools to head as the first time i use the preload tool then if out i leave the spring tensioner in and adjust to that this also works as long as when do the stretch bolts you ensure the sprockets dont move whatsoever,, i lock them off with a number of molgrips etc
