You don't mention what type of sensor. I assume it is a motion detector. Before replacing I would strongly suggest you first remove all power from the system by disconnecting the backup battery inside the control panel then pull the system's power transformer which should be plugged into an electrical outlet nearby. You will know that all power is removed by looking at the keypad - all lights on the display are off. Next remove the motion detector's front cover. Some detectors have a small screw on the bottom so that when removed the cover pops off. Others need to be opened using a flat blade screwdriver and prying off the cover. Once the cover is removed there should be a 4 conductor wire that is wired to a series of terminals. Observe the polarity of the wires, disconnect them and remove wall mounting screws. Install new unit. Be sure when wiring to connect power wires correctly. The 4 conductor wire should have a red (positive) wire and a black (negative) one. Connect the red to the + or pos terminal and the black to the - or neg terminal. Read the instructions that came with the new unit if in doubt. When finished plug the power transfomer back in then reconnect the battery (in this order). If power is connected properly the motion detector's red walk test light (indicating motion) should light whenever you walk in the protected area. Also make sure the system recognizes motion by first closing all protected areas such as windows and doors to get a system ready or green light indication on your keyad, then walk around the protected area. A properly working detector will show you a fault on the keypad everytime the system senses motion.

O2 SENSOR LOCATION


Hi Greg:
On 1995 GMC Truck Sonoma 4WD 4.3L TBI 6cyl the Oxygen Sensor is located under hood, driver side, lower engine area mounted in lower exhaust manifold at pipe flange.


1_12_2012_2_28_20_am.jpg

Fig.: Removing the oxygen sensor from the exhaust pipe

The sensor uses a permanently attached pigtail and connector. This pigtail should not be removed from the sensor. Damage or removal of the pigtail or connector could affect the proper operation of the sensor. Keep the electrical connector and louvered end of the sensor clean and free of grease. NEVER use cleaning solvents of any type on the sensor! The oxygen sensor may be difficult to remove when the temperature of the engine is below 120?F (49?C). Excessive force may damage the threads in the exhaust manifold or exhaust pipe.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

My camera is really blurry; theres a pop-up that says: E:61:00


Press the reset button on the bottom of the camera. Then power the camera off, and power it back on again. "I have a DSC-P50 and was encountering the same problem. I went in to the camera set-up mode with the memory stick removed and changed serveral options (Don't remember which ones, although I do remember trying to change the "Format" setting) When I re-inserted the memory stick, the camera worked. " E 61 00 Difficult to adjust focus Inspect the lens block focus reset sensor
E 61 10 Zoom operations fault Inspect the lens block zoom reset sensor

Engine is difficult to start when cold
  1. Check the battery condition, battery state of charge and starter motor current draw. Replace the battery if marginal and the starter motor if the current draw is beyond specification.
  2. Check the battery cable condition. Clean the battery terminals and replace corroded or damaged cables.
  3. Check the fuel system for proper operation. A fuel pump with insufficient fuel pressure or clogged injectors should be replaced.
  4. Check the engine's tune-up status. Note the tune-up specifications and check for items such as severely worn spark plugs; adjust or replace as needed. On vehicles with manually adjusted valve clearances, check for tight valves and adjust to specification.
  5. Check for a failed coolant temperature sensor, and replace if out of specification.
  6. heck the operation of the engine management systems for fuel and ignition; repair or replace failed components as necessary.
Engine is difficult to start when hot
  1. Check the air filter and air intake system. Replace the air filter if it is dirty or contaminated. Check the fresh air intake system for restrictions or blockage.
  2. Check for loose or deteriorated engine grounds and clean, tighten or replace as needed.
  3. Check for needed maintenance. Inspect tune-up and service related items such as spark plugs and engine oil condition, and check the operation of the engine fuel and ignition management system.

As long as it works, I wouldn't spend too much time worrying about it. In the future, learn to clean the sensor yourself. It's not difficult when you have the proper supplies. Just Google the words "how to clean a DSLR sensor" and you will find sites with pictures to teach you.

DSC light comes on when I run the A/C


It is not your A/C the problem, try this:
1- Apply the brake.
2-Open ignition to on position II engine off.
3-make sure to set A/C to low temp with A/C button off.
4-Start the car while keeping foot on the brake.
5-push A/C button on and make sure that a/c compressor comes on and wait around 10-12 second.
6-Let foot of the brake and wait ,check if DSC light comes on if not pump the brake several time with A/C compressor on if light comes on, if it dose mean your MASTER CYLINDER BRAKE SENSORS NEED CHANGING.
This was the solution for my car,I had exact the same problem.

E:61:00 Difficult to adjust focus
(Cannot initialize focus)

Retry turn the power on by the power switch. If it does not
recover, check the focus reset sensor of lens block (pin ea of CN401 on the SY-183 board). If it is OK, check the focus motor drive IC (IC401 on the SY-183 Main board).

98 mercury villager OBD I code P0135


This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor 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 P0135.
Repair short or open or high resistance in wiring harness or harness connectors.
Since you have already changed out your O2 sensor (as long as you used to OEM replacement and not the "Universal" replacement) you should not have to replace it again. You might check your thermostat to part of the time it takes for the O2 sensor to start switching being based on coolant temp, if your thermostat is not operating properly, it could cause the coolant temp to take longer than what is considered by the ECM to be normal.
