The P1148 code means that the connection to the front sensor is shorted or open.

You may need to replace your O2 sensor.

If the O2 sensor has recently been replaced, check the connection or fuse of the sensor.
If the connection or fuse are Okay, then have Nissan reprogram the ecu with the latest program.

I have a 2005 nissina frontier. I had sensor 1 bank 1 replaced but the check eng. light still comes on with the codes 1148 and 1031


You were right in thinking if you replaced the sensor all would be fixed. But code 1148 means the sensor is not going into closed loop mode, and code 1031 means the heater in the sensor is not working.
Code 1031 could cause code 1148, and the actual problem could be in the wiring harness or the power source for the heater inside the O2 sensor.

How to solve Diagnostic code p1148 nissansentra 04


Code 1148 and 1031 are both for the O2 sensor in front of the catalytic converter. The sensor would need to be tested with a scanner and a multi-meter.

P1148 P1031 P1279 P0420


Well looks like all 4 codes point to the O2 sensor bank one sensor one.
Code 1148 and 1279 are for problems with the performance of the sensor, code 1031 is for a problem with the heater in the sensor, and code 420 is for poor performance of the catalytic converter on bank one which could also be the sensor.
I would probably replace the sensor or switch it with the one on bank two and see if the codes change.

I have an engine code u1000 for my 2005 nissan altima. whats that mean?


basically that is a communication code between one or more computers

you need a dealer scan tool or something similar like the $8000 snap-on scanner to verify which computers are suspect and a DVOM to measure voltage on the communication circuits between the suspect computers

long story short.... this is a job for a select few technicians.... your best bet, depending on where you live.... is the dealer

My 05 altima has several error codes..335 (02,04,and 05) and 725 (01 and 03). The car acts like the starter may be going bad. Would these codes support that problem?


No those codes would not support a bad starter diagnosis.

And those are not correct codes for a 2005....codes should be a 4 digit code

Receiving engine code p0420 on my 2005 altima 2.5 s


A p0420 code indicates a Catalytic System efficiency failure, Bank 1.
Basically, the computer is seeing reduced efficiency of the catalytic converter or one of it's components (such as an 02 sensor)

There may be a few root causes, such as a faulty oxygen sensor, faulty coolant temperature sensor, faulty converter, Large exhaust leak, or retarded (slow) timing.
