OBD II Fault Codes Reference Guide

The Diagnostic Trouble Code numbering follows a standardized structure. All Diagnostic Trouble Codes have a letter followed by a 4-digit number (e.g. P1234). The first letter indicates the type of code:

P = Powertrain

C = Chassis

B = Body

U = Network Communication



The remaining 4-digit number specifies the problem within that system.

My '03 Dreamer constantly has the check engine light come on while cruising...
but NO fault codes! Wha hoppening??!!

Damn dude.......I hope you didn't sit there and actually type all of that......

[knowyourturbo]

Hey there Bud, That's the MOST info I've found on ANY site/forum. I will print it asap......Thanx again...Stew

[poppabear]

great post punch, question, i have a 2003 gt turbo, the engine light has been on for awile, no problems with performance or anything else until i went to get a smog cert. couldent get it cause code poo38 ho2s bank 1 sen 2 heater circuit high. where is this heater circuit ? is it somthing i can replace myself with average skills ?

[CREWZIN]

Pappabear, that's a 6 year old post your replying to.


According to PT Do-It-Yourself.net ...

P0038- O2 Sensor 1/2 Heater Circuit High

Possible causes include:

O2 Sensor Heater Operation
O2 Heater Element
O2 Heater Ground Circuit Open
O2 Sensor
O2 Heater Control Shorted To Voltage
O2 Heater Control Circuit Open
PCM

Which means there's a problem with the Downstream 02 sensor and a scanner tool is needed to further diagnose the problem.

Or, you could just replace that 02 sensor and hope that cures it.

[poppabear]

a little discombooberated right now my baby cant get a smog cert. sorry

[poppabear]

where is the o2 sensor?
