OK. I just got back from Bermuda and the Oxygen Sensor Thread chaser tool arrived in the mail too!
I had the old O2 sensor in the bung and gave it a couple turns to tighten more, then loosened it.
I took he thread chaser and sprayed some liquid wrench chain oil on it - I used this because I don't have too much use for it and figured this is a good application for it.
Screwed the tool/bolt in by hand and used a rachet to tighten a few turns, then unscrew a few turns. Sprayed more lube, tightened and loosend. Repeating the process until the bolt was in as far as I could take it. Lubing all the way.
then I unscrewed and removed it.
Turned the new O2 sensor in by hand - It goes in snugly!
Used the cheap harbor freight offset O2 sensor tool on it and used my breaker bar to tighten it. Done!
Couldn't find my bluetooth code scanner, so went down to Advance Auto parts where I could get it read for free.
P0171, is still there, but now joined by a P0135 codes.
Looked up P0135 and got. I think the P0135 code was caused by driving the car around with the O2 sensor disconnected for a week or two. Hopefully it goes away. I erased the codes and will now drive the car around for a bit.
P0135 FORD - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1
Possible causes Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit open shorted to ground Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit poor electrical connection Faulty Engine Control Module (ECM) What does this mean? Tech notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. If the sensor and connector are OK, replacing the O2 Sensor 1 usually takes care of the problem What does this mean? When is the code detected? Current amperage in the front heated oxygen sensor heater circuit is out of the normal range. (An improper voltage drop signal is sent to ECM through the front heated oxygen sensor heat Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) Possible higher than usual fuel Consumption P0135 FORD Description Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM). In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground. The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
