Most o2 sensors are located on the exhause manifold that is connected to the head of the engine block. There easy to find. All you have to do is Remove the old one and you can pick one up from any auto parts store. i.e. NAPA, Kragen, AutoZone, etc.

I have a 01 ford windstar im getting acode. P1132 can you explain why


P1132
Lack of HO2S-11 Switch, Sensor Indicates Rich A HEGO sensor indicating rich at the end of a test is trying to correct for an over-lean condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. I would change both of the upstream (before the catalytic converter) O2 sensors (cylinder bank 0ne and two). 9 times out of ten this is the right guess to fix this code.

Is p0052 a fuse problem or a o 2 sensor


P0052 DTC trouble code may be caused by one or more of the following:
A short in the heater circuit in the sensor.
A failed O2 sensor heater.
Wiring/connectors broken/frayed leading to sensor and/or relay.
Failed PCM/ECM.

What is p0141b and how to fix it?


Technical Description O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2) What does that mean? 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



Try wiggling the wire to the Oxygen sensor. Probably just corroded or loose! Worst case, $25 for a new sensor.

What does the codes p0442,p0136 &p0141 mean on my 2001 ford taurus it failed inspection for these codes


P0442 FORD - Evaporative Emission System Leak Detected Small Leak

Possible causes- Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
P0136 - O2 Sensor Circuit Malfunction Bank 1 Sensor 2
Possible causes- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Rear Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

How do you fix the oxygen sensor for 1996 ford explorer


pctech1_31.jpg

NOTE: If excessive force is needed to remove heated oxygen sensor, lubricate heated oxygen sensor with Penetrating Lubricant prior to removal.

  1. Disconnect battery ground cable.
  2. Disconnect heated oxygen sensor from engine control sensor extension wiring.
  3. On 3.0L, 4.0L and 5.0L raise and support vehicle.
  4. Remove heated oxygen sensors from exhaust manifold, inlet pipe, or dual converter Y pipe, using an Oxygen Sensor Wrench.
Installation
  1. To install, reverse the removal procedure.
  2. Apply a light coat of anti-seize compound to thread.
  3. Tighten heated oxygen sensors to 36-46 Nm (27-33 lb-ft).

Subaru wrx impreza showing fault code p0037. how do i fix this fault which sensor is it and where is the sensor located?


http://helpforcars.net/obd_codes/codes.php?code=P0037

It's an O2 sensor according to the above link, and it is bank 1 sensor 2 low, the 2 meaning that it is downstream past the catalytic converter but not on the manifold.

- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM) Possible Solution Tech Notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.
Good luck on this repair.

What is the code b0135 in the chevy tahoe.


Harness or connectors (The sensor circuit is open or shorted)
- Front Heated oxygen sensor (Bank 1) may be faulty Possible Solution Replacing the O2 Sensor 1 usually takes care of the problem P0135 Description The front heated oxygen sensor (or sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V. 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 a four thumbs up would be helpful if this fixed your problem thanks have a nice day

Code po141


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.

Here are a few causes, that may have contributed to this failed sensors actions:

A.Open or short to ground in the wiring harness(CHeck the sensor harness for this type of fualt)
B.O2 heater circuit wiring high resistance(Replace this sensor if this exsist)
C.O2 heater element resistance is high(Replace the sensor if this exsist)
D.Internal short or open in the heater element(Replace the sensor if this exsist)

NOTE_Possible Solutions

A. Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
B. Repair short or open or high resistance in wiring harness or harness connectors
