2001 Lexus ES300

Does anyone know what P1150 fault code means and how to troubleshoot?

Appreciate any assistance.

 

Thats related to the oxygen sensor on bank 1 sensor 2. Bank 1 is the one near the firewall. Sensor 2, is the oxygen sensor after the catalytic converter of bank 1. Time to replace a new one.

 

I'm pretty sure it's bank 2 sensor 1. The sensor you need is a Denso 234-9009 Oxygen Sensor.

Be sure to use a Denso sensor, it's cheapest from Amazon.

 

Is anyone sure which sensor it is, i see differing opinions when I start googling.

Thanks

 

Bank 2 sensor 1 is the one towards the radiator

 

Thanks Guys,

I borrowed one of my buddies computer deals and tells me both Bank 2 Sensor 1 and Bank 1 Sensor 2 are reading 3.7 (im not sure if thats volts or some type of percentage it is converting). I assumed the voltage would be below 1V.

I unplugged Bank 2 Sensor 1 and cleared the check engine and trac off, 4 hours of drive time and the fault isnt back yet.

 

Check the oxygen sensor monitor to see if it's complete. If it's not, the CEL will come back on when it detects the problem again.
