There are some codes. The speedometer shows: 'Change Oil' (need to get this done), 'gas cap'. It reads that. There is also the check engine light. I put it on a scanner and the results were:
1. Small leak in the evaporacion system detected. (I already purchased a new gas cap-so that was not the problem the light did not go away). The printout also says there is a large leak in the evap/gas system somewhere.
2. (Different code) The module detects an error in reading the calculation for the air/combustion relation (I am trying to translate from spanish the codes to english).
Probably cause: oxigen sensor. It also says: reaction en H02$11 (Oxigen sensor hot Bank 1 Sensor 1). The truck has 4 oxigen sensors (I believe they are all identical?) So I would prefer to not change all of them as they are pricey if there is a way not to.
Can you please help me with these issues? The truck is all original and in very good shape. It needs maintenance and these 2 issues. Can you please help me with the above issues? I would obviously prefer to buy as few parts as possible. If you also have diagnostic tips to help solve the EVAP problem I would like to try that before taking it to a mechanic (many here have NO idea what they are doing when it comes to diagnosis).
Thank you! Ryan
