Hi all,wat's the normal symptoms of a failed O2 sensor.I'm having issues with unstabilize idling (more obvious on a hot weather),high fuel consumption,no black smoke,noisy knocking (tappet sound from cylinder head)..u think its an O2 reading fault or related to a leaky valvetrain assy from cylinder head.I'm currently using a stock Blacktop.need a bit of help from 4AG sifu.Thx!!

Need some inputs...

Is BT's O2 sensor a 4-wire, heated? Trying to get a Bosch replacement and i think P/N: 15738 is my best bet.

Tried googling for a few days and i found out that :

-Our main O2 sensor is called Before Cat-Con O2 sensor.

-The missing 'ext temp sensor' is actually called the After Cat-Con O2 Sensor. Can someone confirmed if this is true? Is this a unheated sensor?

-I refered to BT ECU. There got 2 pins for O2 sensors. One of the is called 'Heated Oxygen Sensor' while the other one is called 'Oxygen sensor'. Does that mean it has 2 O2 sensors?

Sifu with sensors/ecu knowledge or anyone pls help.... thanks

I got mine from overseas.


Standard AFR for BT 20V (or any other EFI engines) should be around 14.5 to 15.5 as the ECU will try to maintain 14.7 AFR, which is the optimum AFR for idling and cruising. For BT 20V, the AFR will be slightly richer during full throttle 13-ish and reaching to 12-ish between 6k-7krpm. Most high revving engines will have higher AFR during high rev as this is to keep the engine cool and keep on the safe side. But anyways, the O2 sensor will not feedback to ECU during full throttle.


Yup bro, serious. PNP to BT 20V socket. I think I will order 5 pcs first next week and ETA 2 weeks.


Yup, read that on sifu Chin's website a long time ago, but recent check at Wing Hin quoted me RM400 and no stock! UMW Toyota usually sells stuff at higher price as they will usually claim to have the parts shipped from Japan. :banghead:
bro, did u still available to get the cheaper o2 sensor for silvertop? i need it urgent.pls pm me if still have a stock.
