The 1KZ-TE engine has a cast-iron block with Compression ratio rating is The engine is equipped with the EGR system. Redline is rpm. The cylinder block has a monoblock high-strength cast-iron structure with the five-bearing-support system. The cylinder bores were plateau honed for more efficient piston ring sealing. The 1KZ-TE engine is equipped with a fully balanced steel crankshaft that has five main journals and operated on aluminum alloy bearings.

The connecting rods are made from lightweight carbon steel and each rod has an internal oil passage which supplied an oil gallery in the piston. The pistons are made from aluminum alloy and an FRM fiber reinforced metal top ring groove to improve wear resistance. Each piston is fitted with two compression and one oil control rings. The cylinder bore is The 1KZ-TE has an aluminum alloy cylinder head with a cross-flow configuration which is mounted on a steel laminate type head gasket and had plastic region tightening bolts.

The engine has single overhead SOHC high-quality steel camshaft and two valves per cylinder: one intake and one exhaust 8 valves in total. The camshaft is driven by a timing belt and gears.

Intake valves are The Toyota 1KZ-TE engine does not have hydraulic lifters, so special shims are used to adjust the valve clearance. Shims are available in 17 sizes from 2.

Board index Site Information and Help Having problems? Once a few months back I went to start it and it fired and just stalled. About 3 weeks ago I was packed up to go duck shooting first thing in the morning jumped in the truck turned it on felt like it fired up then it died.

I tried re-starting it several times and it just wouldn't crank into life. Eventually I got it going but if I took my foot off the accelerator it wouldn't idle. I could drive it but as soon as it went near idle RPM it died. I pulled the ECU which looked fine - no leaky diodes etc. Truck went fine after that but got the mechanic to check it over when it went in for a WOF - no fault codes showed up but maybe cause I had taken the ECU out.

Anyway, a couple of times since it has stalled the first time I try to turn it on and then takes 2 - 4 goes and it will fire up and run fine. Seems a very intermittent problem and its pissing me off! Has anyone else had this issue and successfully resolved it? It doesn't always throw up a fault code. Can you buy the spill control valve separately? I guess you still need to get a mechanic to pull the injector pump out to access and remove the valve? Bloody thing did it again last night when I got dropped back at the vehicle - only started with a bit of right foot then had to drive with the left foot on the brake and right foot keeping the revs up at intersections etc.

After a couple of kms all was running fine again Anyone ever heard of an injection pumps sudden death? I wonder if it has anything to do with the immobiliser.

I imported the car from UK 5 yrs ago. You do not have the required permissions to view the files attached to this post. Jump to. Who is online Users browsing this forum: No registered users and 0 guests.

Toyota Prius Ecu. Toyota Camry Ecu. Toyota Auris Ecu.Posted: Thu Dec 31, am. After reading about the benefits other people have had replacing the electrolytic caps in the ECU, I finally did mine.

Even though the brand of caps Toyota used in my ECU anyway is a decent brand Nichicon10 years is usually the expected life of electrolytics The first thing i've noticed is definitely less smoke on startup If a normal polarised electrolytic is used here, something might not work properly.

If you can get a 1uF non-electrolytic cap to replace it Always use caps that are rated for the same voltage or slightly higher. Try to avoid using ones that rated far higher like V ones where 16V ones are required as they will probably fail prematurerly due to not reforming properly during each charging-discharging cycle.

It is also best to try and use degree rated caps instead of the 85 degree ones for reliability.

There are cmos chips on the pcb that can be easily fried by static. The pcb is double sided, so means that it can be a pain in the arse to get old components out and new ones in I will be getting my done very soon, we think that I have damaged a cap whilst replacing the alt due to the voltage difference as my torque lconverter ock up is intermittent. Yes we did replace the gearbox whilst at it but the gearbox was in full working order when we swapped it.

Note for those with auto trans models. Your ECU has two PCBs in the one "box" which are connected by a ribbon so extra care is required, there are also two additional "caps" on this board to replace which are uF 10V as stated use 16V. To save silly questions this is due to the one "module" controlling both the engine and transmission, Other manufacturers call this the PCM Powertrain Control Module, Ford and Holden for example I've mentioned this in other threads but the general rule with caps is a hour life at the rated voltage.

This roughly equated to km when doing a case study on a boat however one would think that when averaging out speeds and vehicle use in our applications km would not be an unreasonable figure which seems to equate to when most are rebuilding their ECUs. Buzz Lightyear electric Quad Mr Dog. Any car with door open. I've mentioned this in other threads but the general rule with caps is a hour life at the rated voltage. Posted: Fri Jan 01, am. Well I am going to have to open mine up and do this as well.

It might fix my warm start issues and the missing on cold idle. This is probably the cause as I've got black smoke on startup as well where it didn't have it before. Posted: Fri Jan 01, pm. There is no standard lifespan for electrolytics in general.

How close to their rated voltage they are being run, what temperatures they are being run at etc, can all affect the operating lifespan. Even the rated figures are only indicators. Nothing more. Can we please stop making out that electrolytics crap themselves completely after low duty cycles please? Granted, electrolytics are the most prone of the capacitor family to fail, but no way on earth are they that bad.Starting price. No reserve. Toyota engine computers rely on various electronic components for proper function.

These can fail if maintenance is not performed rendering the car undriveable. If you have bad idle, misfires and high fuel consumption the ECU is often at fault due to leaking capacitors. Please note that due to the age of the components, and various states of condition these older vehicles can be in there is a chance of continued problems beyond the ECU which means I can't provide a total guarantee such an ECU fix will sort your all issues.

It's not possible to guarantee ECU repairs on engine conversion due to the custom wiring that differs from OEM vehicles, there are too many variables and 'bad' custom wiring can easily damage the ECU circuits inside.
