Re: Exhaust Camshaft Timing Toyota 3SFE

This engine has a distributor with a engine speed sensor and a cam position sensor fitted as well as the ignition coil fitted. No map sensor but a vane type air volume sensor.Also no Crankshaft position sensor. Maybe there are different set ups in different countries. This is Australia

Re: Exhaust Camshaft Timing Toyota 3SFE

Thanks for the replies. I was after a wave form to show the cam timing if possible. This vehicle is from another workshop and I looked for an unrelated issue. ( Ignition system ) It actually runs not to bad . I wanted to know whether my assessment is correct because I have no reference wave form. So...

Re: Exhaust Camshaft Timing Toyota 3SFE

I want to add that the car is a Celica ST162R and there are no camshaft phasers and has solid lifters.

Exhaust Camshaft Timing Toyota 3SFE

Attached is the in cylinder pressure wave form of a Toyota engine at idle. I believe that the exhaust cam shaft is too far advanced. On this engine only the inlet cam shaft is driven by the timing belt. The exhaust cam shaft is driven through a gear of the inlet cam shaft. the marking to fit the exh...

Re: Vito 2006 646.980

Reading your post it seems you perform more " Guesnostics " than Diagnostic. The compensation Values are OK with the exception of cyl 2 just a bit high compared to the rest. The ECU seems in control of the injectors. As a rule the sum of all corrections is about O. You should not disconnect or block...

Re: Identifying Piezo vs Solenoid Injectors

No not really. You need to identify by having the correct specification before scoping

Re: Ranger 3.2 Relative compression waveform

Hi Burt, I f you sync your waveform with the firing order 1-2-4-5-3 you could have a head gasket leak on cyl 2 -3 This would be confirmed by the uploaded form with diagnostic software. Normally there are rarely issues with head gaskets on diesel engine these days. Almost always there is a primary re...

Re: Volvo C 30 D (Ford 2.0 engine)

Hi Cam Code You are quite correct that this is a generic fault code.It is set if the system can not maintain a required fuel pressure within its control mapping. The reasons and trigger points to set this code vary by manufacturers and systems. They can include faulty internal injector seals, Low pr...

Re: Volvo D5 relative compression

Hi there,

Have a look at the cam shafts and hydraulic lifters. I believe this engine is prone to failures in this area.

This would lead to incorret calve opening and closure.

About two years ago after extensive research I bought a Pico 4425 advanced kit as well as a WPS500 kit.I am very happy with the performance of the equipment. The deceiding fact...
