    1KZ TE Injector Pump Resistor Modification

    I should have really followed this up ages ago. My CEL at low revs was not caused by the pump being too advanced or retarded. If was caused by a tiny break in the wire that connected to the timing correction resistor. For exactly the reasons that Davet points out this is why the CEL was being...

    1996 Prado 1KZ TE Rough Idle with hunting and insane amounts of black smoke

    So essentially temperature senor assists the ECU to decide how much or little fuel to inject. When it can't do this the idle can be rough or it will hunt. Also, it may cause it to over fuel hence the black smoke.It may do this without throwing an error code. Mine didn't. To be fair, mine was...

    EGR removal/Delete

    Just thought I'd add to this incase anyone is mulling over an EGR delete. So I haven't deleted mine on my 1kz te. It has over 300,000km albeit rebuilt at 220,000. It does however have an oil catch can. I had to have my turbo rebuilt recently so I took the intercooler off to clean out the oil...

    1996 Prado 1KZ TE Rough Idle with hunting and insane amounts of black smoke

    I had a similar issue. It turned out to be a broken wire to the water temperature sensor. Its the one behind the Injector pump near the firewall, not the water temperature sender at the front. Simple change of the connector and sensor and problem solved for me.

    1KZ TE Injector Pump Resistor Modification

    To be honest, im almost at the stage where i know i just need to advance the pump, i just want to satisfy my curiosity about what the timing resistor mod does and how it works!

    1KZ TE Injector Pump Resistor Modification

    Thanks Grimbo. Again, I think this explains what the Fuel Resistor does. My understanding is the screw on the SPV affects the fueling across the whole range of RPM whilst the resistor mod largely affects the lower revs. I believe this was for emission control. What it still doesn't explain is...

    Ah ok. Hopefully someone else will know. Thanks again.

    1KZ TE Injector Pump Resistor Modification

    Cheers for the reply Shayne. Sorry for being simple. Would that not be the fuel resistor (beige) not the timing resistor (grey)? I should have said it was the timing resistor that I was interested in knowing about. Also how is that different from adjusting the spill control valve nut?

    1KZ TE Injector Pump Resistor Modification

    Sorry if this has been done to death on here before. I've been reading/watch plenty of stuff from Oz about resistor Mods. Seems very simple and not sure of the downsides. One thing I cant work out: What does the resistor mod actually do? does it just give you more range to advance/retard the...

    Prado 95 ABS not working

    Brakes feel a tonne better since servicing the rear calipers. I adjusted the LSPV as well and that seems to have helped a lot. All in all, I think i have set of brakes that actually do what they are supposed to!

    Prado 95 ABS not working

    Boom! New wheel speed sensors arrived (£35 each made by Kavo). Fitted them this morning. The ABS light has finally gone out!

    Prado 95 ABS not working

    I've found some partern ones for £35 each so will start with those. While I'm waiting for them to arrive i am going to try repair the current ones. They have broken in an awkward place though. I have a replacement injector pump arriving tomorrow as well so that's the priority for this week...

    Prado 95 ABS not working

    Awesome. On close inspection I can actually see the front sensor cables are damaged around the control arm mounting point. I think this may be our problem. With the fault code I connected Tc and E1 and then removed the short pin, turned to on and it gave me my codes. I see that you can search...

    Prado 95 ABS not working

    SOLVED!!! Sort of at least. The ABS warning light in the dash had been bridged to another disused light on the dash, presumably as a dodgy fix by a local mechanic...TIA! Now getting Error 31 and 32. Just need to work out what they are and get them fixed...

    Prado 95 ABS not working

    No probs. You have been a massive help already. I am not sure what else to do. Managed to find a cheap second hand relay and decel sensor online so I'll try those. Also coincidentally changing the front calipers and servicing the rear. Always had spongy brakes on the car, maybe the stopping...

    Prado 95 ABS not working

    I am thoroughly stumped. ABS ECU tested, checked all the live inputs to the ECU and the actuator, check all the earths, even actuated the ABS pump manually to check it works. Checked the brake pedal switch. Chedked the link connector.. Still the ABS does not work and no warning light. If the...

    Prado 95 ABS not working

    Mine has a rear diff lock fortunately but no ABS light on activation. I have checked every fuse on the vehicle and can't find anything wrong. Ill have a play with the earth wire tomorrow and see what I find. Thanks again.

    Prado 95 ABS not working

    Also I have checked the fusible link in the engine compartment and there is power going through it. Are there any other fuses in the system?

    Prado 95 ABS not working

    So I have put in a tested ECU, still the same issue. I have also checked the 4WD ECU and that is fine. Does any of your vehicles ABS light up when diff lock is engaged? Mine does, thought it would though if its working. Next step i need to test the earth and the live, I pressume I would do...

    KDJ95 Diff lock relay

    Solved. Feel like a bit of a idiot. Went and checked the ECU, everything was fine. Went back and checked all the wires again (using a multi meter this time). Two more wires had broken including the earth to the sensor, hence why I thought that was the problem to begin with. Reconnected and jobs...

    KDJ95 Diff lock relay

    Could be but, I have used the diff lock enough to stop it failing. I'm told there is a trick with a 9v battery you can do to test it but not sure how to do it. I'm fairly sure its an electronic issue as I can no longer hear the relay when I turn the switch.

    KDJ95 Diff lock relay

    Long shot but I want to try revive this thread. I have had issues with my rear diff lock ever since I owned my 1kz. I eventually found the problem, it was a broken wire to the Rear Diff Lock Position switch. A few months after fixing it the same issue. I traced it to another broken wire, fixed...

    Prado 95 ABS not working

    Thanks a mil for looking into that. Agree it doesn't make sense. I have actually pulled out the whole ABS ECU which I have sent to an electronics guy to have a look at. I'm hoping I can start by discounting this before i fiddle with anything else. I have actually worked out how to read the ABS...

    Prado 95 ABS not working

    So checked the ABS computer and it is all connected up. I tried disconnecting and still no warning light. Went further and also disconnected the ABS pump, still no warning light. Reconnected everything and the ABS still doesn't work. Any ideas on what to try next? Was thinking I could open up...

    Prado 95 ABS not working

    So I have disconnected the front right ABS wheel sensor, still no ABS light. Any idea where the ABS computer is located?

    Prado 95 ABS not working

    I know the engine light and ECU is working when it comes to the other sensors such as CPS, water and oil temp etc. I guess I could disconnect one of the actual ABS wheel speed sensors to see if that brings up an error. Anyone tried cleaning the ABS sensors?

    Prado 95 ABS not working

    Im on about 50:50 tarmac and dirt roads. On regular emergency braking (live in Kenya and the driving is terrible) the wheels do lock up slightly but I have never felt the pedal pulse. Could it be possible that the ABS rotors in the hubs have gunked up? Thought it weird that the engine warning...

    Prado 95 ABS not working

    Good Afternoon All, Need a bit of help. My 1kz te is fitted with ABS, but no matter how hard i brake it never engages. The ABS light comes on as usual with the ignition but turns off once started. If I disconnect any of the connectors (ABS pump or deceleration sensor) neither the ABS light...

    1KZ TE 1996 Rough Idle/Hunting

    May have spoken too soon. The rough idle returned shortly after. This time it did bring up an Error code (22) After a pulling out the airbox I spotted so dodgy wiring on the coolant temperature sensor. Tidied those up and it runs a dream.

    1KZ TE 1996 Rough Idle/Hunting

    Problem solved. It was a leak in the fuel line between the filter and the injector. I didnt find it the first time as I thought the leak would be further back so used the same direct from a can. Turn out there were leaks at both ends. Replaced with a clear bit of braided hose resistantto...

    1KZ TE 1996 Rough Idle/Hunting

    Awesome. Ill give it a go tomorrow. Out of curiosity, when you say turn it a little at a time, how little are we talking. Quarter turns or just a few degrees?

    1KZ TE 1996 Rough Idle/Hunting

    Ok cheers Shayne. Ill give this a go. Is the rough idle i am experiencing an indication of over or under fueling? Generally speaking it has plenty of power and already has a little bit of black smoke when I put my foot down (nothing out of the ordinary for an old diesel though)

    1KZ TE 1996 Rough Idle/Hunting

    Hi all, New to the group. Proud owner of a 1996 Prado 95 (1KZ TE). Its had an engine rebuild about 20k km ago. All in all it runs smooth, plenty of power no excessive smoke and no unusual noises. It does have one annoying habit which is that it has a rough idle (regardless of AC). I would...
