Is the signal wire negative or positive?

[@katzenpapa]

Thank you brother! I am a hardcore DIY person and I been wanting to buy a scope for my personal enjoyment! Definitely getting on very soon!

[@kekoagallant579]

Great video. I see so many that don't show hooking up the scope. Thank you.

I’m having a no start issue and p0340 showed up after a month but it finally popped up while cranking I’ve always thought an engine has to be running to pick up a code and it wasn’t in the saved message either that one had a p0011 something over advanced and that was in the saved codes not an actual cel light

[@decthemano]

great video ,could you show what to do if it was a shorted ground signal please

[@t-train6534]

I think that’s the problem with my car I wanted to know that also

[@daverobins887]

Thanks for that OZ nice and clear, is the procedure the same for crank sensor and throttle position sensor ?

[@aboremas7107]

I have the same issue in my range rover 2004. After cicked down the accelerator pedal. I clear code then it come back again. . Thanks oz

I subscribed to your channel because you have a great way of explaining both how the car is supposed to work and how to make a fix (a rare talent). Very clear. I have a cheap multi meter that won't graph the signal wire like yours did. Can I still test the signal wire with my multi meter? Am i doing that on the OHMs setting? Thank you for your video.

[@murkywaters7185]

Yes, use low voltage range which includes 5v and set meter to A/C!

[@randeniweerachandra158]

Hi, I have 2000 toyota avalon with 1mz engine which slightly backfires when trying to start and won't idle and won't rev over 2000rpm. came from other workshop which they done timing belt and water pump, checked timing ok, fuel pressure and other things ok as the car can forced to run. as the car can forced to run around 1500rpm and hold steady but the rpm counter on the scanner goes up and down. draft the crank signal on scanner and sowing erratic signal, changed the sensor still the same.

[@frankrobles4155]

I had problem whith New chinese Cranksensor, and i had to put original Nissan and I solve the problem, Original is more safety, thanks...good video...

[@precisiont5188]

Can someone please help me find the crank position sensor and cam position sensor on my 2014 Ford Mustang v6 3.7? This would be amazing. Thank you.

[@jluke2525]

Sorry this is so long, it's copied from caddy forum i used........... I had the p0008 on my 2010 CTS4. I changed the sensor for bank 1 along with the solenoid actuator. The p0008 is gone, p0342 is now on the CEL. The car did not start until several long attempts. The sensor for the cam was bad and now has a full 12 volt load going to it and no more p0008. Ohms test shows the old sensor defective. The solenoid actuator was not bad but replaced with a new AC Delco part. I show 9 volts input at key on. And 2 volts when running. I also tried the old actuator with the same results. Both actuators show good with ohms result test. The battery has a full charge, Alt putting 14 volts when running. What would make the p0342 voltage drop? If i clear the code it reappears at the next start up. I'm stumped here, any help appreciated. The only odd issue was the long start up of several attempts before it ran. Any ideas? Thanks.

Thank you Oz. Good job. Merry Christmas to you and your family.

+Billy Yoder thank you for watching. And merry Christmas to you as well.

Anyone know what electricmotor is between the firewall and motor...i hear it running and its draining my battery over night...my battery light is on now as well as my e brake light and now launches in 3rd gear .. i had issue with this nissan Maxima 06 3.5 l ...it was cam sensor by battery...but that running fan motor or pump is draining batt...somewhere under the intake manifold....if someone kinda knows what is wrong w it...I really appreciate you taking time to help a not so mechanically smart guy!!;)

[@jmb-bj9gs]

Air pump? ? I think its an emissions thing on start up it pumps air into exhaust to warm it up faster and cut down on emmissons

[@raiya1114]

Autozone have the same sensor from hitachi. It an OE part. Is it working OK so far? It's look different.

[@bobbyparker780]

Where can I find a cheap meter that I can use to check for them waves on sensors and such

[@RampartPh]

is it possible for a failing cam sensor not be sensed and therefore fail to activate a check engine light?

[@OzMechanics]

A dropping 5 volts or ground can cause it but. A dropping 5volts will normally pop a code

[@christianobedoza760]

hi my nissan cefiro a32 model 1997 rev only 2000rpm after i change MAF sensor problem still occure

[@smithraymond09029]

Looks like the previous owner installed the wrong part. That magnetic end on the "old" sensor is way shorter than the factory replacement.

[@oscarcrespo9365]

Value information. Make my life more easier. Thank you guy.

[@rafaelpareja1177]

thank u... this video really helped me a lot....

[@OzMechanics]

Rafa Pareja thank you for watching

[@alpinehs]

The best video about it

[@OzMechanics]

Thank you. I have newer videos testing cam and crank sensors. Feel free to check them out as well

[@emenikepauluzodimma2485]

1 month ago my nissan was scan and found code P0335, use to have hard start and stops while ideling. Finally refused to start a week ago. I changed crankshaft sensor at the back of engine, maintained the camshaft sensor on top of the engine and the car will not still start. i went further to test the resistances of the three sensors.2.74Mohms old crankshaft, 6.98Mohms new crankshaft and 3.89Mohms camshaft. Please any way out.

[@Abizzy84]

Don't buy aftermarket junk

[@philh9238]

good job man! do you own your shop?? like the diag videos better than the "replacement" videos

[@OzMechanics]

phil holbrook thanks man. Yes I do. Been owning my shop for 5 yrs now.

[@philh9238]

must be nice being your own boss.

[@OzMechanics]

phil holbrook does have its ups and down. But overall I wouldn't change it for anything.

[@tracycolorado]

Good job , nice explanation

[@OzMechanics]

tracycolorado thank you very much

[@marcodeluca4068]

hate to point this out but you say the owner google the code for sensor and switched it out so why are you replace sensor again??

[@OzMechanics]

Did you watch the entire video? I checked the signal wire on the sensor they replaced and didn’t show the square signal when cranking. That’s why I changed it out

[@marcodeluca4068]

Oh I didn't sorry whats the part number of where can I buy it ?

[@OzMechanics]

I don’t remember the part number. It’s been a while since that video

[@marcodeluca4068]

np thanks for vid it was great know anything about routans??

[@amr-50]

Thanks Oz

[@jmb-bj9gs]

How do you feel about napa parts ?

[@OzMechanics]

I do t use napa. It’s not because I don’t like them is just there’s not one close to me

[@fire7765]

awesome

[@OzMechanics]

Glad you liked the video

[@juniorpadillah5507]

One more time thank you very much for your help

[@OzMechanics]

Junior Padilla H no problem. Thanks for watching

[@MrDilandy]

The issue wasnt a cheap sensor..it was totally different sensor or incirrect sensor purchased by tge customer

[@OzMechanics]

MrDilandy the customer didn’t buy the sensor

[@Temptedization]

I am sick of the fossil fueled cars, next one will be an Electric when the prices comes down. The up side is no maintenance, there is nothing that can go wrong with EV's, no tune-ups, no transmission, no engine, no hidden sensors like the one I need to replace with a P0340 code engine camshaft position sensor. The car starts and runs fine, but I have this check engine light that will not go out, so I'm concerned that if that sensor goes completely the engine won't start at all one day & then I will junk the car or sell it for parts, so until then I think it will be just for local driving, it doesn't pay to fix a 19 year old car they would have to take half the engine apart to get at the stupid sensor. When everyone goes EV I feel sorry for the repair guys, they will need to retrain.

Nice

[@OzMechanics]

Suki Kuri glad you like

[@ryancrack5875]

My car won’t start I think it is the camshaft sensor

[@OzMechanics]
