I looked up the code you posted, and came back as the camshaft position sensor, which is behind the timing belt cover, if it is the right model.

My check engin light came on the codes came up as po133, p1000 what do i do to fix my car is a 1998 ford windstar?


A code P0133 may mean that one or more of the following has happened:
  • The oxygen sensor is faulty
  • The wiring to the sensor is broken / frayed
  • There is an exhaust leak
the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
  • Check and fix any exhaust leaks
  • Check for wiring problems (shorted, frayed wires)
  • Check the frequency and amplitude of the oxygen sensor (advanced)
  • Check for a deteriorating / contaminated oxygen sensor, replace if necessary
  • Check for inlet air leaks
  • Check the MAF sensor for proper operation
  • code p1000 refers to emission monitors not fully run and requires a couple of drive cycles from cold start to fully warmed drive cycle at different speeds.

Check Engine light with Po131 o2 circuit low voltage sensor 1 bank 1 reading, what does that mean?


- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Front Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

Replacing the O2 Sensor 1 usually takes care of the problem

The front heated oxygen sensor (or O2 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 Engine Control Module (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.

My 2000 Cadillac Deville engine light on. Engine code PO420


Catalyst System Efficiency Below Threshold (Bank 1)

A code PO420 may mean that one or more of the following has happened:
  • Leaded fuel was used where unleaded was called for
  • An oxygen sensor is not reading (functioning) properly
  • The engine coolant temperature sensor is not working properly
  • Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
  • Retarded spark timing
  • The oxygen sensors in front and behind the converter are reporting too similar of reading

  • Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
  • Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
  • Inspect the downstream heated oxygen sensor (HO2), replace if necessary
  • Replace the catalytic converter

Replaced the O2 sensor unit and the ECM(programs installed) but I'm still getting CHECK ENGINE LIGHT(P0001). what is the possible problem and how can this be resolved?


P0001 Fuel Volume Regulator Control Circuit/Open The above code is about an oxygen sensor code for the heater circuit located in bank 1 sensor 1. (bank 1 is at exhaust manifold by the #1 cylinder head, bank 2 is on the 2nd cylinder head. On some engines, both exhaust manifolds could have one oxygen sensor each side and the 2nd cylinder head will have the sensor 2). On the oxygen sensor itself, it has 4 wires which are color coded. Two of wires are for the heater circuit that heats the oxygen sensor to make it reach optimum operation quickly. Those 2 oxygen sensor heater wires could be shorted between the sensor and the ecm (engine computer) or other engine components.
oxygen%20sensor%20heater%20copy.jpgThe common fix for this code is to check the integrity of the heater wires. Check the wires for insulation and routing which could be loose or touching a hot exhaust that can short the wires. If the engine has too many miles, it is possible that the heater circuit inside is worn and shorted which needs a replacement of the oxygen sensor. If you have a DVOM, you can also test the continuity of the heater wires from the oxygen sensor to your computer pins.
More detailed fixes will be provided as soon as you give the symptoms of the obd2 trouble code. ATS will provide the wiring diagram so you can trace the color coded wires. Use an obd2 code reader or scanner so you can access this obd2 trouble code. When you have this obd2 code list, use it as a reference and give the code to ATS. We will then send you all the possible fixes for the obd2 trouble code. ATS has lots of fixes for obd2 gm codes, obd2 ford codes, dodge obd2 codes and all obd2 import codes such as Toyota obd2 codes, Honda obd2 codes, Nissan obd2 codes, etc. All fixes for this obd2 codes are guaranteed or your money back.
Important TIPS about Oxygen sensor:
The oxygen sensor content of the exhaust gas indicates when the engine mixture is operating lean or rich. When the oxygen sensor detects that the engine is operating rich, the signal voltage is high, and any decreases in the signal voltage means the engine running is lean. The engine computer supplies a reference voltage like one volt or five volts, and then shows the change in the sensor return voltage as the sensor's resistance is changing. If you have connected everything properly, when you crank the engine, you should see the check engine light coming out.
Unheated oxygen sensors rely on the heat of the exhaust gases to reach the working temperature, therefore they might start to cool down while the engine is idling and revert back to a default air-fuel ratio setting. This type of sensor usually has a single wire connector, though others have two. Unlike the fuel pump relay, the 02 sensor heater circuits have a separate fuse for each sensor and grounds, which are controlled by the engine computer.
To read a voltage across the heater, one side must be connected to (+) and one side must be connected to (-), which is accomplished by the computer or a transistor. It can read 12V between each wire and a separate ground if it was connected to positive and the other was not yet connected to ground connection (for details, please contact ATS).after you replace oxygen sensor you have to drive for so many miles before it resets its sef

Oxygen sensor codes I have 2 codes PO133 and PO141 says possible defective sensor or faulty HO2S12 or poor connections


Well it could be the wiring too the sensor, a software issue that requires flashing the pcm or the sensor you purchased is not working too the same standards that the old one was. Did you use a one type fit alls 02 sensor that uses the old connector and you have to splice the wires? Read this info...


P0133 - Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)

What does that mean?
This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Symptoms:
You will likely not notice any drivability problems, although there may be symptoms.

Causes:
A code P0133 may mean that one or more of the following has happened:
* The oxygen sensor is faulty
* The wiring to the sensor is broken / frayed
* There is an exhaust leak

Possible Solutions:
The simplest thing to do is to reset the code and see if it comes back.

If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
* Check and fix any exhaust leaks
* Check for wiring problems (shorted, frayed wires)
* Check the frequency and amplitude of the oxygen sensor (advanced)
* Check for a deteriorating / contaminated oxygen sensor, replace if necessary
* Check for inlet air leaks
* Check the MAF sensor for proper operation



P0141 - 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


Hope helps (remember rated and comment this).
