Apologies for sounding of..it's not possible to see other folks problems on the end of a keyboard😫 ..
Of course you do what you have to do and take the best option for yourself.. I can see why the parts is your best option... Hope it's easily sorted 👍 |

Yes, as mentioned its a picoscope .. The automotive version as opposed to the labs scope.. But I have a little handheld dso that serves as a multimeter or scope , made by onwon, that is OK for quick checks , without the need to drag laptops out etc 👍 |

Once you have the key
 you can see if any DTC’s are present and point towards the cam or crank sensors. An absence of DTC’s tends to point to a VCV issue.
Even if no DTCs then you can still check the wiring continuity from each sensor to the ECU with a multi meter, visual check wiring for chafing, check connectors are not damaged. See wiring diagrams three and four on this link https://www.lrworkshop.com/wiring-diagram/...e-controls. Once you have tested / checked the wiring given you have purchased the camshaft and crankshaft position sensors already, I would change the crankshaft position sensor first, see if that rectifies the issue. If not then change the camshaft position sensor to see if that rectifies the issue. |

Hi... here is a link to the pico automotive site..and various products..
https://www.picoauto.com/products/automoti...t/overview The scope I've been using up till fairly recently is a 4423...which is a 2 channel automotive scope..i doubt its available now..I've had it years..but the equivalent will be the new 4225A.. the decision will be whether to go for a 4 channel scope , which if you get into this sort of thing is handy, but at the time I couldn't afford one so got a 2 channel which I've only recently changed for a 4 channel.. Pico we're never cheap but the price appears to have shot up in the last few months😳.. Their software is free and constantly been upgraded ..and generally regarded as a top quality product even if expensive to buy the hardware.. |
