Engine Light And Fault Code P1135

[Perfection]

Does anyone know the following fault code mean?

P1135

The following data was also retrieved from the scan tool.

P1135 Sensor values:

Calculated Load 8.63 %

Coolant Temperature 84. C

Short Term Fuel Trim Bank 1 0. %

Long Term Fuel Trim Bank 1 -7.03 %

Short Term Fuel Trim Bank 2 0. %

Long Term Fuel Trim Bank 2 -3.12 %

Engine Speed 1829 rpm

Vehicle Speed 28 km/h

I have checked on the website and found the following info.

"Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)"

See any of the experts could help me here without the need to pay for the dealer to fix.

Regards,

Perfect.

I think you need to talk to moonstone mart.

Try pm'ing him.

Cheers

Bank 1 Sensor 1 was the one I had replaced . On a Rav there are 2 sensors before the cat in the manifold and two after. It was one of them before and naturally if you trawl the web these are the dearer ones. You can buy a spanner with a cut-out to allow the wires not to snag when changing them. Would be interested to know how you get on.

Hi there,

I have a reply from another forum. P1135 is the pre-heater sensor that is closest to the gearbox.

I have measure the circuit an confirmed its open circuit. I will try and buy one to replace.

I think I can use an adjustable spanner to remove and replace the sensor.

i wouldnt use an adjustable m8 if you chew the end off that sensor you will be nackered :o

You're right, I have seen something call lamda socket or wrench. Do you know what size I need?

I have seen some 22mm for around £5

Report back with progress....

Bought the part from Toyota for £170 and fitted today, and hurray!! its fixed now. Fault code is cleared.

Resistance measured 1.3 ohms on new pre-heater for future reference (Bank 1 Sensor 1 - Top right hand side or shortest lead on the sensor).

Perfect.
