How many O2 sensors does a 2007 Mazda 3 have?
Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
What are the symptoms of the p2251 trouble code?
The O2 sensor for bank 1 sensor 1 has an open circuit in the heater circuit. What are the symptoms of the P2251 code? The Check Engine Light will be illuminated and the code is set in ECM memory as a fault. The ECM may lose control of the fuel control circuit for the O2 sensor for bank 1 sensor 1.
What does p2251 mean on an O2 sensor?
Although generic, the exact repair steps may vary depending on year, make, model and powertrain. A stored code P2251 means that the powertrain control module (PCM) has detected a negative current discrepancy in the upstream oxygen (O2) sensor for engine bank number one. Bank one is the engine bank that contains the number one cylinder.
What does a stored code p2251 in PCM mean?
A stored code P2251 means that the powertrain control module (PCM) has detected a negative current discrepancy in the upstream oxygen (O2) sensor for engine bank number one. Bank one is the engine bank that contains the number one cylinder. Sensor 1 denotes the upstream (pre-cat) sensor. The negative current control circuit is a ground circuit.
How much does it cost to fix a p2251 code?
The cost of diagnosing the P2251 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

What to do if your car has code p2237?
If the code P2237 continues to be reset, start the engine. Allow it to reach normal operating temperature and idle (with the transmission in neutral or park). Connect the scanner to the vehicle diagnostic port and observe oxygen sensor input data on the data stream.
