Mazda OBD codes P0031 P0051 P0037 related to exhaust manifold?
I have a 2000 Mazda MPV that had a cracked exhaust manifold. I took it
to the dealer and they replaced it under warranty. However they still charged me $85 to run the OBD codes. I know, I got ripped off. I just went to AutoZone and ran the codes myself and came up with P0031, P0051 and P0037. These all indicate failed O2 sensors. Shouldn't these failures be related to the cracked exhaust manifold? Basically, I want the dealer to refund my $85 and reset the Check Engine light for free. From my research they usually charge about $100 because you have to take apart the dash. Great design. Thanks in advance. |

Any scanner can plug into the obd11 port and clear codes, about 3 minutes

The dash should not have to come apart. The port for the OBDII machine
is usually under the dash on the drivers side and takes only a few minutes to reset the codes. The dealer should have done at least one of these 2 things: 1) Have the diagnosis included with the warranty as the codes derive from the warranty work. 2) If they cannot include it with the warranty and are not willing to cover the diagnostic cost then the codes get reset after the warranty work because it is part of scanning it in the first place and you paid for it.

I should probably clarify. I went to AutoZone and used their OBD scanner. That is how I know the codes. When I had the repair work done, they told me the codes were from "Arching spark plug wires" and therefore not covered under warranty. Then I went to Autozone and read the codes myself. I have cleared the codes but two, P0031 and P0051, keep coming back. My main question is can the bad O2 sensors be a result of having a cracked exhaust manifold? They tried to f*** me once, so I am sure if I don't have my facts straight they will try again. Ken wrote: > The dash should not have to come apart.

A cracked manifold can definitely cause a false code. Extra air is getting pulled into the exhaust system. Since air is 21% oxygen, it'll easily throw off the fuel mixtures and set a code... EDIT: I don't think the crack could cause an O2 sensor to fail, though. -- corning_d3 ------------------------------------------------------------------------ corning_d3's Profile: http://www.automotiveforums.com/vbul...?userid=373828 View this thread: http://www.automotiveforums.com/vbul...d.php?t=616665 http://www.automotiveforums.com |
