As i was driving to work my Check Engine light suddenly came on. I just checked it for codes and the following codes were shown;

Current Fault
P0132 Sensor Circuit High Voltage (Bank 1 Sensor 1)

Pending Fault
P1456 Powertrain

Can someone explain the differences with the faults please.

As for the P0132 code i am going to replace the sensor. I honestly thought it would be easy. But i went to the Denso website to try and buy the OEM part for my vehicle. But i see there are different ones available.



I am confused on the Upstream Downstream subject

I checked Amazon

Robot Check

But all of the ones i clicked on says it's not compatible, all except for the following, which i am unsure if it's the part i need.



Please help me, I'm sure this is one of the simplest things to fix. But i am a newbie and know almost nothing about cars.

Can't tell you what sensor without knowing model (LX, DX, EX or HX) and year. You'll also need an O2 sensor socket, they're $8-10.

P1456 is an EVAP (evaporative emissions) leak in the fuel tank.

Being a newb, the best thing I can tell you is to get a service manual. You can get a paper copy for about $50 here: Service Manuals, Owner Manuals, Wiring Diagrams, Service Bulletins - Helm Incorporated or get a download or CD of off eBay for cheap.

I forgot the most important part, didn't i lol. I'll look around for a Service Manual.

You need the upstream for the D17A2. It should be about $50. The primary O2 sensor is in front (upstream) of the catalytic converter.
