No problem!
I agree. From these images I can say with good certainty that the ECU is likely repairable. (BTW it appears to have been repaired at least once before, judging by the non-standard caps in the first photo). I don't understand why would the ECU repair shop deemed it unrepairable.
I...
As @FJ40 that green thing stated, it is unfortunate that you had this experience.
Also, X2 his idea...If you want, you can post a decent photo or two of the damaged area(s), this will help me assess if it's indeed unrepairable. Please keep in mind although I have the experience this is a...
@kzj78dp
According to my research, all the non-electrolytic capacitors are okay to leave in circuit due to being manufactured using different formulation, lack of electrolyte, or the utilization of non degrading ingredients such as mica or tantalum.
Replacement of the 1uf bipolar capacitor was...
Thanks @kzj78dp !
Yes you are correct. For my own ECU recap I opted for higher voltage/duty hours capacitors. That was an experiment that worked well since I knew that you can go up in the voltage but not the capacitance. Higher duty and temperature tolerances are never a bad thing to have...
@specter
You are most welcome!! Glad to help..
Now, if you are attempting to do the recap yourself, remember to take your time cleaning. IPA and flux are your best friends.
Cheers!
Okay, here is the list of correct caps as ordered from Digikey. Use the manufacturer # in the search and add them to the cart. Since these caps are very affordable I would suggest that you order two sets instead of one just in case you bugger one during install.
Good luck!
@FJ40 that green thing
Thank you! And yes that is certainly not fun. I also suspect that the alternator job may have been the last straw for the ECU capacitors, but of course these old electrolytic caps are just going to fail and spew their guts sooner or later.
Having professionals do the job...
Lol, unfortunately I don't have the PN. I was only going with the Google search results for shopping. The MAP sensors I saw did look like the one on a 1KZ-TE though. Sorry!
Best of luck.
Again, the crankcase position sensor related code could be a manifestation (symptomatic) of the outcome of a separate issue, like a different fault causing the crankcase to "think" it's malfunctioning. Please remember this is not always the case, of course.
Now the MAP sensor...
I am currently overseas away from my truck. But I did a quick search and the 1KZ MAP (manifold absolute pressure) sensor is on the side of the intake manifold closer to the front of the vehicle. There should be an online guide on how to test one with a multimeter.
My theory is (although I could...
Yeah that is certainly not fun. These trucks are really good and reliable, but just like anything else that is old, some parts start to fail. I don't think the injectors are to blame (although a replacement/rebuild is never a bad idea) mainly because I understood that the truck is idling okay...
@MIKADO Z
Thank you for your comment.
My shifting anomalies we're all fixed with the ECU recap. I didn't have any lights coming on, just a sporadic inability to shift from 2nd to 3rd, and a much more common inability to shift to 4th. The truck was randomly downshifting one gear without...
@kgrove
Since I did the job myself, I don't know of a specific person who is qualified to do the job that is willing. I do know that @GTSSportCoupe is qualified and have performed this very procedure before I did. But I can't verify if he is taking orders.
With that being said. I do know that...
Lucky bunnies 😆
Yeah if your ECU/ECM/TCM etc is not included in the capacitor plague then you may be fine for a long time. All electrolytic caps fail with time and likely before other components on a PCB. I even contemplated replacing them with tantalum caps but unfortunately those don't seem...
Thank you @janyyc you are very kind. You are correct about all the talent we have on this forum but I am certainly not one 😆. I just know that everything is figuroutable if you don't rush things and do your homework lol.
With that being said, I do believe that a preventative replacement of the...
Hello friends!
Some of you know that I've been chasing an intermittent shift anomaly on this newly imported KZJ78. I started with the basics, connectors inspection, AT fluid flush, and AT filter/solenoids replacement. Although these measures did help reduce the frequency of the shift weirdness...
