Hey Trixie passed smog! Tirns out the issue was a vaccuum leak caused by bad injector O-ring.

I had similar issue. Catalytic converter was nearly plugged.

I had a similar issue. Turns out the pnuematic system on transmission what a clot in it. Clean it out and solved the problem. Anither time wiyh similar issue was the master air sensor had a crack it it.

Hiya. Original owner of 2000XE needs computer.Replaced front catalytic converters. Replaced timing belt. Replaced oxygen sensors and checked wiring harness already yet still can't pass smog. Error codes showing low voltage to oxygen sensor. Please recommend a source. Anyone know of a trusted...

Car eins great but a bit more exhausty since replacing the sensors

Work was done at a smog and repair station. He thinks it's the computer.

Hello. Any ideas what to do next?

Yes. I replaced all 4

Okey I had the sensors replaced. She still won't pass. The codes are now: PO 131 Bank 1 Sensor 1 Low Voltage PO 151 Bank 2 Sensor 1 Low Voltage Next steps?

Thanks. I found: NTK: downstream right. Bank 1. Sensor 2 Upstream right Bank 1. Sensor 1 Upstream left. Bank 2. Sensor 1 Downstream left. Bank 2 Sensor 2 These are all the NTK under Xterra 2000 v6 3.3 so I think this is it, right? I am ordering but if I am wrong pls let me know and U will...

I am thinking the sensors are first. At the start, Trixy wouldn't pass smog due to random misfire. Plus, there was loss of power on hill acceleration. Replaced the timing belt at 70 thou and the misfire.cleared up, car runs great. Now there are the O2 codes which had been masked by the misfire...

Yes that is encouraging. I will replace the sensors. Do hou think it's worth the money to get Nissan parts?

will do. Do you know.of a viable.source for computer when she needs one?

So true. The mechanic believes they are likely ok and a new computer is needed. I can't find a compatible computer anywhere. So maybe do the sensors and hope fie the best.

Did the cats about a year ago.

Timing belt?

Finally got the diagnostic codes. P0151 02 Sensor Circuit Low Bank 2 Sensor 1 Then: P0131 2 Sensor Circuit Low Voltage Bank 1 Sensor 1 Please advise. I Really love this car and need her to pass smog.

Ok. Thanks.

First code was intermittent random misfire but new timing belt fixed that. No it is Oxygen Sensor but mechanic says they look fine. I replaced a little over a year ago. The check engine light is always on. It flashes sometimes. 240,000 miles. Original owner.

Hiya folks. I drive a 2000 XE which runs great except it won't pass smog. Mechanic thinks she needs a new computer. Thing is, Nissan sez they don't make them anymore. I need some ideas where to find one. Thanks, Susan.
