1998 nissan altima trouble code p0135


The code P0135 means O2 sensor heater circuit malfunction bank 1 sensor 1. This means you most likely have a bad O2 sensor. The possible causes are:

TT - Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit poor electrical connection
- Faulty Engine Control Module (ECM) Usually the code indicates a bad Oxygen sensor, but an intake vacuum leak or a failing fuel pump can cause the code, so check your intake vacuum hose for a leak or hole. But most likely, you have a faulty Oxygen sensor. Now Bank 1 Sensor 1 means the bad O2 sensor is the one on the number one cylinder side (which is the cylinder closest to the timing belt or where all your belts and pulleys are),which is bank one. If you look really closely, you will see that the number 1 cylinder is just a little bit closer to the belts than the number 2 cylinder. Now that you know which side you are dealing with, the next step is which sensor. There are two O2 sensors on each side (upstream or downstream), four total. Sensor 1 is the upstream sensor, which is before the catalytic converter closest to the exhaust manifold. Number 2 sensor is on or after the catalytic converter. So in short, you are replacing the O2 sensor on the Number 1 cylinder side before the catalytic converter. They are a pain to remove. Get some Pb Blaster lubricating oil and spray on the threads and let sit for 10 minutes and spray it again. You will need a 7/8 Oxygen sensor removal socket to remove it. Don't forget to disconnect negative battery terminal and O2 wire harness first.. Any questions please feel free to email me. Good luck.

This is Bank 1 (closer to the dash panel) Sensor 2 (located after the catalytic converter).

---
Note: A malfunctioning front oxygen sensor may cause fuel trim codes to set.
  1. Several Diagnostic Trouble Codes use specific terminology to refer to sensor location. The illustration and key below explain the following terms:
  2. Engine BANK Bank 1 is closer to the dash panel, (also referred to as RH or right hand). Bank 2 is closer to the radiator, (also referred to as LH or left hand).
  3. UP Refers to Sensor 1 or "front sensor". It is located closer to the exhaust manifold and before the catalytic converter.
  4. DOWN Refers to Sensor 2 or "rear sensor." It is located after the catalytic converter.
  5. The following examples show how to interpret oxygen sensor terminology:
  6. B1/S1 = Bank 1/Sensor 1 = Dash panel side, BEFORE the catalyst or "upstream"
  7. B2/S2 = Bank 2/Sensor 2 = Radiator side, AFTER the catalyst or "downstream"

5 error cods on my 2002 Jetta GLS 1.8 Turbo Engine


P0420= Catalyst System Efficiency Below Threshold Bank 1
P0300=Random/Multiple Cylinder Misfire Detected
P0301=Cylinder 1 Misfire Detected
P0172=System Too Rich Bank 1
P2181=Cooling System Performance
you need to write these down,have someone clear the codes in the car,then go for short ride and recheck which if any code reappears.it's like domino's affect,one sensor can start a chain affect with the others.

Code # P0141 and P0138


You said you changed the O2 sensors, which ones? I do believe that sensor 2 is the Catalyst efficiency monitor, it looks like an O2 but it's function is different. This sensor is behind the Catalytic converter, the O2 is in front. Bank one is the bank that # 1 cylinder is on, so the sensor that is defective is the 2nd sensor back on that sides exhaust pipe.

P0141 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 2

P0138 - Heated Oxygen Sensor (HO2S) Circuit High Voltage Bank 1 Sensor 2
