Po 171, po 305, po 441


Hi, I know from my past experiances the spark plug wires at the boot ends than slide onto the sparkplugs usually over time short out due to the metal tubes that protect the sparkplugs from heat kind of ark across from the metal tube through the plug boot causing an error code. Sometimes in the dark you can actually see them arking at the tube on the engine, and also hear a crackling noise. As to the code for the O2 sensor that's a normal wear and tear item that may need replaced. As all vehicle age over time electrical connections, and things have issues develop and cause havick with sensors and computers in these vehicles too.


As with the 441 code and then the other code for the O2 sensor showing up may mean both O2 sensors are going bad if your system has 2 sensors in the exhaust, usually one before the cat converter and one behind it. A lot of this also is due to what gasoline you use in the vehicle over time. Lower octane gas may be what is causing things to act up.

What's your problem? my 2004 mercury monterey has eight codes ,po301,poo53,po106,po316,po300,po304,po305,and po306


PO 300 is multiple misfires detected
PO 301, 304, 305, 306 are misfires in cylinders 1,4,5,&6
PO 053 is HO2S Bank 1 Sensor 1 Heater Resistance
PO 106 is MAP/BARO CKT Range / Perf
PO 316 is Misfire detected 1st 1000 Revs.

On a misfire, I usually push towards the spark plugs, plug wires, and coil packs / distributor coil.
You have PO 106 and PO 053 that need to be inquired about at nearest AutoZone.
They can give you an idea as to what is the problem on these.

Did a MAP sensor **** out and cause all the misfires ?
Did a misfire cause the MAP sensor error?
You see what I'm saying ?...Something caused all the misfires...thinking MAP...but not that familiar with the function of the MAP.

Hope this helps...

Error codes po 134 po 153 po 154 po 155 po 171 po 174


PO 134 = 02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 1 SENSOR1)
PO 153 =02 SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 1)
PO 154 =02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 2 SENSOR 1)
PO 155= 02 SENSOR HEATER CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)
PO 171= SYSTEM TOO LEAN (BANK 1)
PO 174= SYSTEM TOO LEAN (BANK 2)
I WOULD SAY YOU HAVE FAULTY OXYGEN SENSORS CAUSING THE ENGINE TO RUN TOO LEAN REPLACE THEM AND YOU SHOULD BE BACK IN BUISNESS

I have a error code reading of PO 743, Torque converter clutch, what does that mean?


It sounds like the convertor in the exhaust system is partly blocked. You will need to have this checked at a shop. Frankster016
