Customer Question

I'm having trouble with code $7EA and 7E*
JA: Fortunately, the mechanics here speak code like it's their native tongue. They're great at getting to the bottom of things, and it would be my pleasure to put you in touch with the best one for this. Tell me a bit more about what's going on so he can help you best.
Customer: The light came on and the codes read $7EA and $7E8 , what does that mean?
JA: Are you hoping to fix this yourself?
Customer: No, but I would like to know how much will cost ?
JA: OK! The Pontiac Mechanic will help you with the diagnostics so you are sure to get this fixed right. I'm not sure of the exact price, but there's only a $5 deposit. The rest of the price information will be on the page I send you to.
Customer: ok
JA: Is there anything else the Pontiac Mechanic should be aware of about your Pontiac?
Customer: My Traction control light and the ABS lights can on also
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Pontiac Mechanic about your situation and then connect you two.

Hello both of those codes point to fault with the exhaust / cataylst Check for exhaust leaks before the O2 sensor as if this has been experiencing an exhaust leak then it will have been running very rich as the sensor will see the extra air pulled in as fresh / lean fuelling and be adding fuel to compensate. this can lead to catalyst failure as the extra fuel can re-light inside and melt the catalyst The best way to find an exhaust leak is to run the engine from cold and feel around the exhaust joints with your bare hands - you'll have about 30 seconds before it all gets too hot and you should feel any escaping gas blowing over your fingers what is prone to problems is the flex joint cracking as per the image

Hido you still need help?Bear in mind that the site takes a deposit from you at the beginning and this is held by the site until you rate my answer at which point the cash is split between the site and the expert. I am only paid for my work on this question if you rate my answer, using the star system at the top of the screen. Please do not forget! Thank you
