Hi, Peter, I love your videos and it has helped me a lot. You describe stuff in a very effluent way. I have the same car as in this video, but a different problem. I tried to find if you have covered it, but no luck. As per my research my Speed Sensor [not the idle speed sensor (which controls the RPM meter)] is malfunctioning. The problem I am facing: - Put my key to ON position and my speedometer shows 20-40 KM/H reading. - When I am driving the car to normal conditions, it keeps floating between 20-180 KM/H abruptly. - Even in traffic jams it is constantly above 20 KM/H. Can you tell me if I have got to a correct conclusion? Also If you can like make any video illustrating how to diagnose the sensor, and also replace it in case it is faulty it would be very helpful. I would be very thankful of yours if you do that. Thanks a lot for your hard work!
2007 Toyota Corolla my speedometer still works but the vehicle rev out high wen I drive it . Code p0500 .and I had replaced the output sensor and same thing .
Hello Peter, I followed this video and it did not work. I changed the idle sensor and still did not get the results you are getting. Is there another way to test? I have a AE111 which was originally a 4A-FE but now a 5A-FE. Many thanks in advance.
Hi Peter, I got a problem with my 4afe 1995. The idle is so good. It is very steady but whenever I will turned on my aircon, the rpm will drop from 800 to 700rpm. I would like to ask what are the things I need to check? I just think that it would be related to IAC valve. Thank you in advance.
bro, with ac on idle 700-1000 rpm is acceptable idle 800 with ac off and ac on goes to 700 means IAC is working normally, if IAC is bad it already stalled
@@PeterFinnTheCarDoctor Thanks have found the connections in the diagnostics box. The motor increases speed when l connect the two positions in the diagnostics box but my corolla idles rough even after cleaning the throttle body
Hi Peter You applicated the idle speed control by diagnosis with the cable. Was the engine hot or cold ? or Does it metter cold or hot to check it . Does work idle speed when the cold or hot time changes cold or hot mode.
Can anyone try this test and leave the wires connected for like 15 seconds and see if the engine rpm increases for the full 15 seconds? On my car the rpm increases for about 5 seconds and then returns to normal while the wires are still connected. I'm wondering if my IAC is defective and needs replacing. Any info would be greatly appreciated.
HI Peter ihave toyota corolla model 98 .when i start my engine my idle speed is getting more 1500 after around 10 monutes.back to 1000 .and when the engine hot the idle speed gp down to 700

Hi, Peter, I don't know if you know about '94 Toyota Coronas, but I have a problem and think you know the answer. My car has been sitting since the beginning of the Pandemic, and now the Speedometer is not working. Could you please help me solve it?
When i start my corolla engine when cold the fast idle speed is 2000 rpm for a few soconds. Is that normal for these cars or do i need to do a fix on it?
Hello, I did the same procedure, the revolutions go up and then go down on their own without me having removed the cable. Do you think the idle valve is the problem?
Hi peter. I have Toyota Corolla 1997 engine 1.6 I went to auto zone for check engine. The check with machine. Code number P0125 it’s mean oxygen sensor. I bought online oxygen sensor and put it. After 10 minutes Check engine light come back. I went to again to the auto zone. The check with machine the said upstream oxygen sensor have problem. When I put oxygen sensor the car burnout? This case. What is problem of my car. Still check engine on. Do I need change fuel injectors spark plugs and fuel filter ?
I’ve got a 02 CE 1.8liter with a Manuel trans. My Speedometer doesn’t work and I’m having a heck of a time trying to find the censor. Where can I find it? The one I ordered doesn’t look like the one that’s on it

Hi, I have the Toyota with 4efe engine, now these days sometimes the idle goes 2000rpms from cold, the most times was normally about 1300-1200 from cold, what do you think? the iacv is faulty? Thanks in advance.
Hi Pete I have a Toyota starlet 4efe. It goes sluggish and putts on take off and up hills and almost stalls, I have replaced fuel filter and checked plugs they are fine ,it feels like fuel delivery but I undone nut at end of fuel rail like u show in your video and petrol seeped out , so could it still be fuel pump or do the symptoms sound like throttle position sensor?
Hello Peter.. my car registers two error codes. Error code 12 and 52. I took the car to the mechanic and he replaced the knock sensor (original Toyota part). On the way home the check engine light turned on again, same error codes - 12 and 52. I noticed that every time I turn the car on, the check engine light is off, after idling, the check engine light turns on again - same codes. I removed and cleaned the throttle body and the IAC - now I get one error code only - error 52. When I follow the testing on this video, I connect the wires, the motor speed becomes higher for about 4 seconds and then returns to normal - even though the wires are still connected. Any help would be greatly appreciated.
o.k thank you. When I connect the wire like in this video, the motor speed becomes higher but returns to normal after about 4 seconds - while the wires are still connected - so maybe IAC is defective ? The car is still in the mechanic - any info will help.

It drags the cars down and then back to normal. What can be the problem?
thank you for reply sir, but what I mean is when I insert the cable in the diagnostics, my engine idle go down not up. does it mean my idle up sensor is broken?
