bronzee Posted August 13, 2009 Posted August 13, 2009 Hi guys, One of the guys over here has just purchased a 350 and the engine management light is on constantly. He was just given the numbers, so searched them out: P0031 O2 Sensor Heather P0037 O2 Sensor Heather P0051 O2 Sensor Heather P0057 O2 Sensor Heather So question being what does the Sensor Heather relate to??? Alex, or anyone else that might know. There are other issues, but we're onto those. If anyone knows, if they would please pm me, given the time difference. Quote
Chris`I Posted August 13, 2009 Posted August 13, 2009 I beleive it to be O2 sensor Heater, not Heather. That might make it a bit easier to work out whats wrong A P0031 DTC (diagnostic trouble code) refers to the O2 sensor (oxygen sensor) located on Bank 1 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2. This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is. It detects the amount of oxygen in the exhaust gas compared to the outside air and then vehicle's computer adjusts the air/fuel ratio going into the engine. The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the A/F O2 sensor. Essentially this P0031 code means that the resistance of the heater circuit is lower than normal. In most cases, that resistance level must fall below 0.8 A to trigger the DTC code. Quote

It sure would help. What I put was cut and pasted (someone can't spell). That makes sense now. Quote
bronzee Posted August 13, 2009 Author Posted August 13, 2009 Thanks Chris. End of the day here, can't be stuffed. Quote
Chris`I Posted August 13, 2009 Posted August 13, 2009 Yeah, the internet is a dangerous place, mis-information is as freely available as information When googling, I usually try to find a few places that say the same thing before believing its true Quote
ZMANALEX Posted August 13, 2009 Posted August 13, 2009 Immy As what Chris has said plus. P0031 Heated O2 Sensor Heater Control Circuit Low (Bank 1 Sensor 1) P0037 Heated O2 Sensor Heater Control Circuit Low (Bank 1 Sensor 2) P0051 Heated O2 Sensor Heater Control Circuit Low (Bank 2 Sensor 1) P0057 Heated O2 Sensor Heater Control Circuit Low (Bank 2 Sensor 2) You have PM. Alex. Quote
Chris`I Posted August 13, 2009 Posted August 13, 2009 Thank you very much Alex. Well on the way to fixing it now I'm sure Quote
bronzee Posted August 13, 2009 Author Posted August 13, 2009 Yeah I hope so for his sake. He purchased the car at someone's word. Sigh..... But I guess some people can be so dishonest when selling cars. Alex you are an absolute champ as always. Quote
