ipobarethieves:
take it to auto mech workshop. Gadzu still sleeping on

olasunkanmimart:


I will bro. Just wanted to be sure that's all.

Barrywilly:
Take it to another auto electrician for rescanning. It is definitely the knock sensors. I think maybe the right one was not used. Change the two knock sensors. Make sure you collect the original ones first removed.

mammanbawa:
Turn on overdrive
There's a light on your dash that says "o/d off"
There's a switch on your gear lever
Press it
The light will go off
You're good to go

olasunkanmimart:



That's not the problem Sir.

olasunkanmimart:



That's not the problem Sir.

Good day,
Please my wife's car would not shift from 3rd to 4th gear and would hit about 4k rpm.
It was diagnosed with obd II scanner and knock sensor, speed sensor, 02 sensor were reported.

Knock sensor and 02 sensor was changed, the car still wouldn't shift from 3rd to 4th gear.

I also noticed that the abs light is constantly ON but not reported by the scanner.

Also, the speedometer won't read.

Professional with similar experience so please guide me on what to do.

Thanks

GAZZUZZ:


Replace knock sensor. Do not touch the transmission

AutoMoTech:

I deduce from this details you only scanned the engine not the transmission. So pls as suggested kindly scan the transmission and also the ABS module.

olasunkanmimart:



Thanks man? Knock sensor replaced and the car is good to go but the speedometer and temperature gauge isn't working.

chukel:
After replacing the knock sensor, is it still showing code for knock sensor? If yes, check to make sure u replaced with appropriate functioning knock sensor. If yes, check the wire harness of the knock sensor. For the speedometer, first check the fuse for abs and make sure it's not cut. If bad, replace.

olasunkanmimart:


No code for knock sensor, no code for abs too but the abs light is ON on the dashboard.

chukel:
there is code for abs. Just that the scanner you are using is limited in function and can't pick up the abs code. Check all the fuses both in the cabin area and the engine bay. Replace any broken one. Specifically look for the one that controls abs

olasunkanmimart:


Bros I dey use Launch Connector Diagnostic-Tool Bluetooth-Adapter Dbscar X431 Pro.

It can even scan for tire pressure not to talk of abs....

chukel:
you can't have abs light on without a code. Ur scanner does not scan Abs
