Current (amps)=Watts/Volts =2000/120 =16.75 =16.75 amps
16.67 Amps
Newer oxygen sensors are heated for accuracy. If the heater element goes bad the oxygen sensor doesn't work and needs to be replaced. If you have an oxygen sensor heater malfunction, it just means that the oxygen sensor has failed.
I=U/R so 30/2000=0.015 so 15 mA

No.
Yes you can.
heater sensor circuit Chevy astro 2000
There is no fuse. It means there is a problem in the catalyst moniter heater circuit bank #2, sensor #2. here is a brief description of why this code was set: During testing the HO2S Heaters are checked for opens/shorts and excessive current draw. The test fails when current draw exceeds a calibrated limit and/or an open or short is detected. Possible causes: Short to VPWR in harness or HO2S. Water in harness connector. Open VPWR circuit. Open GND circuit. Low battery voltage. Corrosion or poor mating terminals and wiring Damaged HO2S heater. Damaged PCM wiring. Damaged HO2S heater. Damaged PCM.
Trouble code P0141 means:O2 sensor heater circuit malfunction (Bank 1 Sensor 2)
In an AC circuit it flows both directions, in a DC circuit see website below. http://www.madsci.org/posts/archives/2000-02/949953455.Ph.r.html
Trouble code P0135 means: O2 Heater Circuit (Bank 1, Sensor 1)
Trouble code P0141 means:O2 sensor heater circuit malfunction (Bank 1 Sensor 2)
Newer oxygen sensors are heated for accuracy. If the heater element goes bad the oxygen sensor doesn't work and needs to be replaced. If you have an oxygen sensor heater malfunction, it just means that the oxygen sensor has failed.
Trouble code P0042 means: HO2S heater control circuit malfunction (bank 1 sensor 3)
I think it is called the heater motor and has a circuit breaker and a 40 amp fuse in the under hood fuse compartment.
The O2 sensor heater circuit helps warm up the O2 sensor. The purpose of this is to allow O2 sensor to get to normal operating temperature without having to wait for exhaust pipes to warm up so it can give accurate readings. It is built into O2 sensor.
I=U/R so 30/2000=0.015 so 15 mA
You have a short circuit/over current problem with the circuit. If the wires are not touching metal, then the starter may have failed.
