O2 sensor install question

Trying to get a O2 sensor connector unplugged. Japan's connectors are a *****... over engineered for special services that are unnecessary. Any suggestions welcome. The harness is hard to get to. I pulled off the wiring bracket to make it some what easier. I know they have plug-less but many after market sensors don't have the same color wires. You don't want to splice in the wrong wire to a terminal.

The O2 sensor connectors are a straight-in push and snap-lock design. Are you sure you've got the right connector? On the passenger side, look along the main intake manifold collector, just below it, halfway back, and you'll see two connectors on a bracket. You can also see the O2 sensor down in the exhaust header, so you can follow the wire up to see which connector is the correct one. Best way to separate them is what you're doing - slide the connector off the mounting bracket and then undo it - it just takes some swearing at it and the use of a small flat-blade screwdriver to separate the clip.

The driver's side connector is at the top of the engine, at the back, mounted with an identical connector next to it. Same deal there - remove from the bracket (just slide it sideways), swear at it while prying, and it'll disconnect. Because of the heat in the Z's engine bay, sometimes those connectors will stick, but there are no real tricks to it - they unclip and separate. Yours are sticking due to heat exposure. Just keep at it and you'll get them.

Removal & Installation

3.5L

WARNING When disconnecting the sensor electrical connector, do not pull directly on wire going into sensor.

  1. Disconnect the negative battery cable.
  2. Disconnect the heated oxygen sensor electrical connector.
  3. Use a socket such as a crowfoot wrench to remove oxygen sensor.

To Install:

NOTE When replacing an O2 Sensor, the PCM RAM memory must be cleared, either by disconnecting the PCM C-1 connector or momentarily disconnecting the Battery negative terminal. The NGC learns the characteristics of each O2 heater element and these old values should be cleared when installing a new O2 sensor. The customer may experience driveability issues if this is not performed.
  1. After removing the sensor, the threads must be cleaned with an 18 mm X 1.5 + 6E tap. If reusing the original sensor, coat the sensor threads with an anti-seize compound such as Loctite 771- 64 or equivalent. New sensors have compound on the threads and do not require an additional coating. Tighten the sensor to 28 Nm (20 ft. lbs.) torque.
  2. Connect the heated oxygen sensor electrical connector.
  3. Install the wiring clip to the heat shield.
  4. Connect the negative battery cable.

Testing


NOTE Allow the O2 Sensor to cool down before conducting the test. The O2 Sensor voltage should stabilize at 5.0 volts. Raising the hood may help in reducing under hood temps quicker.

  1. Turn the ignition on, engine not running. With the scan tool, actuate the O2 Heater Test.
  2. With the scan tool, monitor O2 Sensor voltage for at least 2 minutes. Does the O2 Sensor voltage stay above 4.5 volts- If so, sensor is normal.
  3. If voltage does not stay above 4.5v as indicated, check wiring and connectors. Check O2 sensor for contamination.
  4. If wiring from the O2 sensor is damaged, DO NOT repair it; replace the O2 sensor.
  5. Turn the ignition off. Allow the O2 sensor to cool down to room temperature.
  6. Disconnect the O2 Sensor harness connector.
  7. Measure the resistance across the O2 Sensor Heater element component side. Resistance for either O2 Sensor should be 2.1-2.7 ohms.
  8. If the O2 Sensor is not within range, turn the ignition off.
  9. Disconnect the O2 Sensor harness connector. Turn the ignition to ON; engine not running.
  10. With the proper scan tool, actuate the O2 Heater Test.
  11. Using a 12-volt test light connected to ground, probe the O2 Heater Control circuit in the O2 Sensor harness connector.
  12. If the test light illuminates brightly and flashes on and off, replace the O2 Sensor.
  13. Confirm the repair with the appropriate Verification Test.
  14. Turn the ignition off.
  15. Disconnect the O2 Sensor harness connector.
  16. Disconnect the PCM harness connector.
  17. Measure the resistance between ground and the O2 Heater Control circuit in the O2 Sensor harness connector.
  18. Is the resistance below 5.0 ohms- If yes, repair the short to ground in the O2 Sensor Heater Control circuit. If resistance is okay, go to step 20.
  19. Confirm the repair.
  20. If resistance was okay when measured in step 17, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.
  21. If the resistance is still not within specified range, replace and program the Powertrain Control Module in accordance with the service information.
  22. Confirm the repair.

How to replace 02 sensor p0141 bank 1 sensor 2?


there are only two O2 sensors on your vehicle. The one before the catalytic converter is bank 1 sensor 1 (also known as upstream). The one after the catalytic converter is Bank 1 Sensor 2 (also known as downstream).

You will need to jack up the car and safely support it in order to crawl under the vehicle to access the downstream O2 sensor. Unplug the connector and use a 7/8" wrench to remove the O2 sensor from the exhaust pipe. Install the new O2 sensor, tighten until snug, and plug in the connector.

1997 plymouth voyager w/ codes: P0140 O2 sensor circuit no activity detected (bank 1(2) sensor 2


The Powertrain control module (PCM) will provide a .45 volt reference voltage to the Oxygen sensor. When the O2 sensor reaches operating temperature, it will generate a voltage that will vary depending on the oxygen content of the exhaust. Lean exhaust generates a low voltage (less than .45V) and rich exhaust generates a high voltage (greater than .45V). O2 sensors on a specific bank marked as "sensor 2" (as this one is) are used to monitor emissions. A Three-Way Catalyst (TWC) system (catalytic converter) is used to control tailpipe emissions. The PCM uses the signal received from Oxygen sensor 2 (#2 indicates aft of catalytic converter, #1 indicates pre-converter) to read efficiency of TWC. Normally this sensor will switch between high and low voltage at a noticeably slower rate than the front sensor. This is normal. If the signal received from rear (#2) O2 sensor indicates that the voltage has "stuck" between .425V to .474 V, the PCM determines this sensor is inactive and this code will set.
Potential Symptoms Your check engine light(CEL), or malfuction indicator lamp (MIL) will be illuminated. There will not likely be any noticeable drivability problems other than the MIL. The reason is this: The rear or post catalytic converter Oxygen sensor does not affect fuel deliver(this is an exception on Chryslers). It only MONITORS the efficiency of the catalytic converter. For this reason, you will likely not notice any engine trouble.
Causes The causes for a P0140 code are fairly few. They could be any of the following:
  • Shorted heater circuit in O2 sensor. (Usually requires replacement of heater circuit fuse in fuse block also)
  • Shorted signal circuit in O2 sensor
  • Melting of harness connector or wiring due to contact with exhaust system
  • Water intrusion in harness connector or PCM connector
  • Bad PCM
Possible Solutions This is a fairly specific problem and shouldn't be too difficult to diagnose.
First, start engine and warm up. Using a scan tool, watch the Bank 1, sensor 2, o2 sensor voltage. Normally the voltage should switch slowly above and below .45 volts. If it does, the problem is likely intermittent. You'll have to wait for the problem to surface before you can accurately diagnose.
However, if it doesn't switch, or is stuck then perform the following: 2. Shut off vehicle. Visually check the Bank1,2 harness connector for melting or chafing of the harness or the connector. Repair or replace as needed 3. Turn ignition on, but engine off. Disconnect the O2 sensor connector and check for 12Volts at the Heater Circuit supply and for proper ground on the heater circuit ground circuit. a. If 12V heater supply is missing, check the proper fuses for an open in the circuit. If heater circuit fuse is blown, then suspect a bad heater in the o2 sensor causing a blown heater circuit fuse. Replace sensor and fuse and recheck. b. If ground is missing, trace the circuit and clean or repair ground circuit. 4. Next, with connector still unplugged, check for 5 Volts on the reference circuit. If this is missing, check for 5 Volts at the PCM connector. If 5 Volts is present at the PCM connector but not at the o2 sensor harness connector, then there is an open or short in the reference wire supply between the PCM and the o2 sensor connector. However, if there is no 5 Volts present at the PCM connector, the PCM is likely at fault due to internal short. Replace PCM. ** (NOTE: on Chrysler models, a common problem is the 5Volt reference circuit can be shorted out by any sensor on the car that uses a 5 Volt reference. Simply unplug each sensor one at a time until the 5 Volts reappears. The last sensor you unplugged is the shorted sensor. Replacing it should fix the 5 Volt reference short.) 5. If all the voltages and grounds are present, then replace the Bank 1,2 O2 sensor and re-test.

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).

Symptoms: 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



P0339 - Crankshaft Position Sensor A Circuit Intermittent
The Crankshaft position sensor also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Powertrain Control Module (PCM) or Electronic Control Module(ECM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.

- The crankshaft position sensor (POS) signal sent to the ECM is intermittent
- The proper pulse signal from the crankshaft position sensor (POS) is not sent to Tech notes
- Sometimes and in some models, low battery voltage or a weak starter can can trigger a Crankshaft Position Sensor code.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall

Possible causes:
- Harness or connectors (The sensor circuit is open or shorted)
- Crankshaft position sensor may be faulty
- Signal plate may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead (Weak) battery

Possible solution:
- Charge battery
- Repair harness or connector
- Replaced Crankshaft Position Sensor.

Trying to remove an o2 sensor that befor the cat off 200 caddy escalade


To remove the O2 sensor you will need an O2 sensor socket that you can buy at most auto part stores, or you can dis-connect the wire connector for that O2 sensor, and then slip the wire connector from the O2 sensor through a 7/8 inch box end wrench and then slide the wrench up to the O2 sensor and then remove the O2 sensor. Use plenty of W-D40 to soak the base of the O2 sensor before removing it, and if the wire connector does not fit through the box end of the wrench then cut the wire connector off from the O2 sensor, and you will only need the open end of the wrench to install the O2 sensor, and only tighten the O2 sensor up until you feel the the sealing rings crush down, and do not over-tighten the O2 sensor because they are not supposed to be torqued down.

How to install oxygen sensors on 2000 Honda Accord?


The easiest way is to purchase the direct fit O2 sensors as you don't have to mess with splicing in a new connector. You will need a special O2 socket, and ratchet or a suitable wrench.
First locate the sensor(s), find the exhaust manifold, there should be one there, then follow it back, and you will see the other(s).
Disconnect the connector, then remove the O2 sensor with the socket or wrench. You may need to spray some WD40 or other similar lubricant if it doesn't want to come off.
Just do the opposite to install.

The oxygen sensor may be difficult to remove when the engine temperature is below 120°F (48°C). Excessive force may damage the threads in the exhaust manifold of exhaust pipe.
  1. Start the engine and let it warm up to 120°F (48°C), stop the engine and disconnect the negative battery cable.
  2. Detach the electrical connector from the oxygen sensor.
  3. Using a special, oxygen sensor socket, remove the oxygen sensor from the exhaust manifold or exhaust pipe.


NOTE A special anti-seize compound is used on the oxygen sensor threads. The compound consists of liquid graphite and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service sensors will already have the compound applied to the threads. If an oxygen sensor is removed from the engine and if for any reason, it is to be reinstalled, the threads must have this anti-seize compound applied before installation.
  1. Coat the threads of the oxygen sensor with anti-seize compound 5613695 or equivalent.
  2. Install the sensor and tighten it to 30 ft. lbs. (40 Nm).
  3. Reattach the electrical connector to the sensor and the negative battery cable.
