2000 Toyota Tundra Code P00155

If memory serves you have a fuel line from tank to engine and a vent on both sides.

2000 toyota tundra code p00155. P0155 is a very common OBDII code that occurs in the Toyota Tundra. Replacing 02 sensor Bank 2 1 in a 2000 V8 4WD Tundra. I have a 2000 toyota tundra v8 2wd pickup truck my check engine light came on and i got the codes it was reading p0155 so i changed both o2 sensors on the front side of the system.

I am going to attempt this myself found the sensor do you have to unhook the battery before you start or just at the end to clear. The purpose of the heated element in the oxygen sensor is to quickly bring your O2 sensor up to normal operating temperature after the vehicle has been started. Heated oxygen sensors contain heating elements to help them get to operating temperature quickly in order to minimize the amount of time spent in open-loop operation A fixed rich mixture.

It appears to cover 2000 through mid 2002 V8 2UZ-FE engine Number 1 oxygen sensors. It is caused by a failure in one of the oxygen sensors heated elements specifically bank 2 sensor 1. This trouble code references a number that is given to you when you plug your Tundra into a OBD2 scanner and has to do with the emissions system.

If your Toyota Tundra has registered it means that the ECMPCM is getting a signal from the engine coolant temperature sensor ECT that the engine is not warm enough to enter closed loop fuel control. I have a tundra 2000 SR5 and have just received a 7yr90000 oxygen sensor warranty enhancement notice from Toyota covering the P0135 and P0155 diagnostic codes. Code P0155 occurs when the powertrain control module tests the upstream heated oxygen.

Maintenance Repair I replaced the 02 sensor bank 2 sensor 1 and it still sets code. Asked by GuruY1M5B Mar 15 2018 at 0538 AM about the 2000 Toyota Tundra Question type. The code will go away once the problem is resolved if its not fixed and you clear the code it will come on again right away.

I am now on my third freakin sensor to solve the CEL PO0135 code. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. After a long trip during which I cleared my P0420 code which pops up pretty regularly my monitors were ready and no codes were stored.
