Greetings,

About a year ago it did my timing belt on my 2001 S60 T5. Car runs great, with the exception of ever since then it throws the P0014 code, exhaust cam over advanced. I reset the code and it returns after 40 miles of driving. My guess is that I'm off a cog on the timing belt. My question is, which direction am I off? The timing marks all look to be on. Which do I move, the exhaust, intake, or crankshaft pulley....and which direction? Thanks in advance for any help, my car is failing emissions testing because of this code.

Hey did you ever figure this out? I'm having the same code on my Volvo s60 after doing the timing belt myself . suppose ill just try adjusting the exhaust cam a little bit each way . .

 

I have the same code coming up,

​​I'm hoping I can just replace my camshaft position sensor?

I haven't thought about the timing belt. It was done not too long ago .

 

I just got one of these in the shop - 2014 S60 T5 with weird timing errors - mainly P0016 affecting intake cam - not exhaust cam. Confirmed physical timing of cams/crankshaft is on the marks. No drivability, stumbling, or performance issues have been detected in the shop or by the owner - car runs flawlessly. In VIDA, error occurrence is showing less than 30%. Live data in VIDA shows the actual camshaft timing changes that happen with abrupt throttle inputs track very closely and rapidly with the nominal or target timing values. However, at a steady idle, the intake cam values vary randomly +/- 3 degrees from the target value of 15 where the exhaust cam's angle values stay locked within a degree of the target value. Exhaust cam adaptation is nominal at 27 where intake is 69 - higher than the 57 +/-8 value quoted as nominal in VIDA. It takes a couple of days of driving for the CEL to return after the code is cleared. Installed new VVT solenoid - error persists. Checked engine wiring harness resistances. Chemically cleaned ECM connector. Checked solenoid resistances. Changed intake VVT hub - problem persists. Changed intake cam sensor - problem persists. Checked resistance back into ECM from VVT solenoid connectors - consistent measurements of 150k ohms for exhaust and 175k ohms for intake circuit (pins 86 and 87 of ECM). Double checked to ensure that resistance of engine wiring harness for these two circuits is .1 to .3 ohms for each (continuity).
For reference, I checked the same input impedance of the ECM's pin 86 and 87 on an earlier T5 (2006) that has never had any timing issues. Resistance is as one would expect - 65k ohms exactly for both VVT solenoid circuits. Conclusion: 2014 T5 ECMs have problems with the VVT solenoid control circuits - likely a manufacturing defect that results in a highly resistant connection within the ECM over time. Since these ECMs are mounted to the engine and constantly are exposed to extreme heat cycles and vibration, any defect in the manufacturing process is likely to be exposed over time due to the harsh environment - right behind the radiator fan and mounted to the engine - a stupid place to put an ECM if you ask me.
