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.

I have a 2005 Freestar Se and the P2196 and P2198 problem? Is this the fuel pump problem and how do I fix the problem?


codes p2196 and p2198 refer to the oxygen sensors
p2196 is the HO2s sensor 1 bank 1--signal stuck rich or no signal===causes HO2s --fuel pressure --injectors ---air intake restricted---wiring ---ECM
for p2198 it is HO2S 1 bank 2 --signal stuck rich===causes --same as for p2196

Check engine light is on and i got error code p1133. what is that?


Faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1
- Vacuum leak
- Faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 harness is open or shorted
- Faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 circuit poor electrical connection

The Powertrain Control Module (PCM) monitors the Heated Oxygen Sensor (HO2S) activity for 90 seconds after closed loop operation has begun. The PCM determines if the front HO2S is functioning properly by counting the number of HO2S-1 Lean/Rich (L/R) and Rich/Lean (R/L) switches.

If the Powertrain Control Module (PCM) determines that the front HO2S did not switch enough times, the PCM will set the P1133 code.

replace the o2 sensor

Service Engine light code 431


Here is the definition for code 431.

P0431 MITSUBISHI Description The Engine Control Module (ECM) monitors the switching frequency ratio of heated oxygen sensors 1 (front O2 sensor) and heated oxygen sensors 2 (rear O2 sensor).

A three way catalyst converter (Manifold) with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2. As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase.

When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed. The problem could be the catalytic converter, one of the O2 sensors, or an air leak in the exhaust system.

P0131 sabb 93 2001 po121 error codes


P0131 - O2 Sensor Circuit Low Voltage Bank 1 Sensor 1 (sensor is before the catalytic converter)

Possible causes- 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
P0132 - O2 Sensor Circuit High Voltage Bank 1 Sensor 1
Possible causes- 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

I am not really sure what is going on here with the same O2 sensor giving these lean and rich codes, if nothing else is apparent and the engine runs well you may have a defective O2 sensor.

P0037. heater sen. where is it on the engine?


The code is for the heater in the O2 sensor bank one sensor two. That would be the sensor after the catalytic converter on bank one.
It could be the sensor itself or the power supply for the heater.

What is the code p00300


this is an obd2 trouble code table, it can help you understand the meaning of code.
for po300:
Possible causes of OBD code P0030:
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 Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse - Faulty Engine Control Module (ECM) The Error code is generally activated on detection of the following conditions: The P0030 is set when the ECM detects an open or shorted to ground condition on the heated oxygen sensor heater circuit
Possible Solutions:
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. HO2S Heater Control Circuit Bank 1 Sensor 1 is the generic definition for the P0030; however your vehicle's manufacturer may have a different definition and information for the P0030 code.
hope help.

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.
