Check your fuse and replace any that are burnt out. It is possible that it your heater on your O2 sensor shorted that it blew the fuse.

P0141 error code - mitsubishi diamante 1998

It is the O2 Sensor. Are you sure you replaced the correct one or have you replaced all of them. My vehicle has four. Based on what I have found it appears your car has four also. Have you replace those or just the one you can see. You will have one each at the Catalytic converters, whioch are called the down stream sensors. You will also have two upstream sensors on the exhaust pipes near the exhaust manifolds.

Engine Light on --Scaning appeare Code 0141

P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141. See also: P0135 (Bank 1, Sensor 1).

You will likely notice poor fuel economy the illumination of the Check Engine Light.

Causes: A code P0141 may mean that one or more of the following has happened:
* open or short to ground in the wiring harness
* O2 heater circuit wiring high resistance
* O2 heater element resistance is high
* Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Possible Solutions
* Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
* Repair short or open or high resistance in wiring harness or harness connectors

Hope helps (remember to rate this answer).

I got a p0141 code on my 2001 tacoma v6 what is the problem

p0141 indicates that the heater in the upstream (#1) oxygen sensor has failed. It will take longer for the O2 sensor to heat up, taking longer for the computer to go into closed loop, which burns more fuel. Replacing this sensor is pretty easy, I believe it involves removing one plug and two bolts. After it's replaced, any auto parts store with a code reader can turn the check engine light off, for free.
