Just Threw My First Code, Heated Oxygen Sensor

[LD50]

Well Shortly after I went offroad and bounced all around, I noticed my check engine light on. Got home, printed off codes and checked it out.

 

I got one long blink, 2 more after a short break that seemed to stay on longer, and then a group of 3, group of 4 and a group of 5.

 

First blink means it starts with 1 i think? Then added up, the rest of the blinks tell me 14... 14 = vehicle speed sensor, right?

 

I wasnt sure if the slightly quicker 2 blinks meant anything, but they are shorter than the first and longer than the last 3 groups.

 

Is a vehicle speed sensor integral to driving abilities or will it just affect speedo, etc? Need to drive into the city the next 2 days

 

EDIT - looking over the ecu diagnostic sticky and looking at my printout from another source - i am highly confused. Am I looking at the check engine light blinks or the red/green ecu blinks? And, I may have cleared the code also.... Maybe I'll go for a drive and see if it gets thrown again

your looking at the ECU lights. one red blink and 4 green blinks would mean code 14. 3 red and 1 green would mean code 31 and so on.

I think you were watching the diagnostic selector mode where it flashes once, twice, three times, four times, five times and then repeats. After it flashes three times you're supposed to turn the screwdriver back all the other way and then release it. Then it will flash any stored codes.

 

This is all written up in the How-To section... :tonguefinger:

ok that was easy... Got 3 reds and 3 greens = 33 - Heated Oxygen Sensor. In the how-to, it says 3 green blinks for .5 seconds may have to do with the MAF sensor.

 

I'll start off with cleaning the connectors and my filter. any further input would be great (if needed)

 

 

edit--

 

Everything looked fine, filter is good, connector at MAF is fine. Going to gas up in a few, but I think it will probably go again. Am I going to blow something up if I keep driving?

Nope.....if it's your O2 sensor, you'll be fine, but your truck could run rough, and your mileage will suffer.

Runs fine, milage sucks anyway. Thanks Simon!
