camshaft sensor

**Mentis** · May 9th, 2016 07:55 PM

There are 2 sensor, involved in p1345. Camshaft position sensor (cmp) at Crankshaft position sensor (ckp).
Napa-check mo na ba ang wiring baka lose lang at yung mismong sensor? Bakit hindi mo dalhin sa ibang auto shop para magkaroon ka ng ibang opinion at matest nila ang mismong mga sensor, actually kung matyaga ka lang kaya mong i-DIY yang pagtetest basta may multi-meter ka lang.
At mas ok gumastos ng 5k+ para sa 2 sensor kesa sa 65k😂 agad agad tapos yung mismong sensor lang pala ang problema.
Anyway, 2nd 3rd opinions are better than one. Goodluck!

unfortunately some replies of this thread are not correct and mis leading. the 4JHI fuel system is a VP44 injection pump. betan is right, the cam sensor ay kasama sa injection pump, i don't know if you can buy it separately (maybe sa mga surplus pwede kand magtanong kung pagbibilhan ka). but first a trouble code does not indicate a failure of the sensor kaya sabi ng code ay circuit problem. and 1 thing ho for correction purposes lang (peace) camshaft position sensor ay not located sa may flywheel it's the ckp crankshaft position sensor. tip pag 2 wires inductive type pag 3 ay hall-effect type.

Ergo, the 65k is for the replacement of the injection pump assembly as a whole plus calibration, then?

Makes more sense. In my experience, no sensor will cost anywhere near that much!

yes i think yung quote sa kanya ay whole pump. kung cmp sensor ang problema maybe baka sakali may mabile, if ang camshaft tone wheel ang problema ay wala sigurong choice kundi palitan ang pump assy.

You were reffering a hall type sensor and I am with the magnetic type.
I am not misleading, its part of my job nature which is related to the sensors alike.
Google it and look for the actual images.

onga kaso depende pa rin sa sasakyan kung anong klaseng sensor ang ginagamit. either the AC type (2 wires) or DC (3 wires).....

saglit lang brader. hinay hinay laang.

ayon sa librong meron ako para sa isuzu 4ja1tc/4jh1tc e DTC P1335 (flash code 43) ay crankshaft sensor habang ang DTC P1345 (flash code 41) ay sa camshaft sensor......

a very short article regarding vp44s although still needs to be confirmed,

Bosch vp44 injection pump failures explained

tulad nga ng pump failure explanation madali lang ma diagnose ito though you will need a scanner and oscilloscope. since nag iistart pa ang vehicle ay intermitent failure un code. by looking at the freeze frame makikita mo dun ang mga kundisyon kung kailan lumalabas ang dtc. example kung lumalabas ang code pag mainit na may chance nga na sa psg (pump module) circuit board baka nag oopen ang connections (solder) pag mainit na. sa scope naman makikita mo kung erratic ang signal ng cmp. syempre sa isang shop mas sure nga na magpalit ng pump kaso nga lang ay napakamahal.

thanks so much for the enlightenment. yes sir, the quotation of 65k is inclusive of the calibration of the pump. i am based in davao city and im still looking for shop to do the tests as suggested here. car is running but the anxiety is there. i cant take it for a long drive as it might just stall and wont start again. salamat mga masters. ill just update here once repairs are done.
