Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)
- What does that mean?
Symptoms
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.
Causes الاسباب
You will likely not notice any drivability problems, although there may be symptoms.
Possible Solutions الحلول المقترحه
A code P0133 may mean that one or more of the following has happened:
- The oxygen sensor is faulty خطأ في الاشارة
- The wiring to the sensor is broken / frayed الكيبيل الذاهب الى الحساس مقطةع او مجروح
- There is an exhaust leak يوجد تهريب في نظام العادم
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 افحص عن اي تهريب في نظام العادم
- Check for wiring problems (shorted, frayed wires افحص الاسلاك الذاهبه الى الحساس )
- Check the frequency and amplitude of the oxygen sensor (advanced فحص الترتيب والقيم المعطاه من الحساس )
- Check for a deteriorating / contaminated oxygen sensor, replace if necessary فحص او استبدال الحساس
- Check for inlet air leaks فحص مجرى دخول الهواء
- Check the MAF sensor for proper operation
