Normally you have one sensor in front of and behind the catalytic converter. And most Ford products have two cats. On your Ford you may have one in front on each bank and then one after the cat.
Number 3 would be after the cat converter.

SOURCE: Check engine error code P0155

If you used the type you splice the wires, recheck the wires. Sensor 1 should have been the one up closest to the exhaust manifold. I prefer to pay $30 more and get the OEM plug-in type. You might try disconnecting the battery for a while.

SOURCE: code PO147 02 heater circuit, bank 1 sensor 3

basically it means the 02 sensor on bank 2 detected a lean condition. on v-6/ v-8/ v-10 is usually the side of the engine that does not have cylinder #1. In the vast majority of cases, simply cleaning the MAF sensor does the trick. also check vacuum lines. you can buy maf sensor cleaner at mostly all auto parts stores. just follow directions on can. check the maf sensor first.

Replaced:plugs,wiresdistributor,fuel pump.truck wouldn't start before but now it starts but i am getting po135,po141,po147.po300 codes


P0135 means 0xygen heater circuit malfunction, P0141 mean 02 heater circuit bank1 sensor 2 (this is catalytic monitor) P0147 means 02 heater sensor circuit bank 1 sensor 3, P0300 is random misfire. You will get all the 02 code because of the misfire correct the misfire and the 02 should correct.We will start with the plug wire and make sure the firing order is correct 1996 chevy blazer that will make it a 4.3 engine size check the firing order firing order is 165432 also check the coil (it has a tendency to short you will know if it is) cansmo_181.gifcansmo_182.gifmake sure the distributor rotation is check

Specifically sensor 3 bank 1 oxygen sensor 2000 GMC Jimmy 4.3L v-6 4wd


Skolruby, There are four different codes for bank1 sensor3 as i think you may have written it backwards. It goes as follows, code po143 ho2s circuit low voltage bank 1 sensor 3 po144 ho2s high voltage bank1 sensor 3 po146 ho2s circuit insufficient activity bank 1 sensor 3 po147 ho2s heater performance bank 1 sensor 3. If you are getting code 44 lean exhaust. or 45 rich exhaust, It will show up on an emmisions test witthout the check engine light on and fail. If you get code 45 you might have a csefi fuel meter leak, A common problem with this engine. It is hard to detect unless you dissesemble it and see raw gas by the plastic injector tubes. I have the same year and model jimmy. It took days on a diagnostic machine to shake it out, What a pain. good luck.

Where is the #3 bank 1 oxygen senser located on the exhaust system of my 1999 chevy s10 4x4 4.3 liter v6 pick up?


The oxygen sensor is located in the flow of exhaust and there will be two. the first is at the exit of the exhaust manifold where the head pipe attaches before the converter and the other is just after the cat converter.
