I have a 2002 Honda Accord LX V6 2 Door

Question

Codes

P0131 O2 sensor low input

P0108 MAP sensor high input

P0122 TPS sensor A low input

P0420 catalyst system efficiency below threshold

I know it needs new spark plugs and TPS. .. my question is if I change TPS will it possibly get rid of the other coads? Don't won't to spend unnecessary money. .. it's a has loap to it when it idels sometimes. .. some days it runs great some days it runs like shit!! It's been giving me coad P0420 for a long time now ( I hate it but catalic converts have been hulled out prob 7 years ago ) but I have felt like it wasn't connecting with the car at times finally last night I leave it plugged in while I'm going down the road and it give me these 5!! Could it be my ECM??? Btw it's got 250,000 miles on it !!

Answer 1

The plugs and TPS will only fix the P0122 TPS code, and possibly the P0420 code, but not the other ones.

For the P0131 code you must replace the O2 sensor to fix the problem and for the P0108 the MAP Sensor.

Thank you so much for your time! Just to be clear are you saying spark plugs might fix the TPS  code?

My mistake "The plugs and TPS will only fix the P0122 TPS code"
