Hello!

So right after I lowered the Jag and put the rims. I installed some blue headlights off of ebay for $20.

A day later, one headlight blew. I replaced with original and poof...nothing.
Then the other went right after, and I replaced with original and nothing.

I checked all the fuses including f16, f17, and f67.

I removed all fuses to check and now I have engine codes P0057, P1647.

Where can I start? Could it be the connector? The relay? I'm running out of options and a little disappointed since I did all the upgrades to the car. No check engine light was on before and lights were working perfect.

Let me know..

 

Wierd. Did you check for voltage at the plug?

 

So the headlights work. I bought brand new headlights and they worked.

Still have the check engine light on with codes P0057, P1647.

Whats weird about the whole thing is I never had the check engine light until I removed all the fuses in the engine bay checking for a bad one. Can it be a short or something somewhere?

 

One of the codes if for the o2 sensor upstream and the other for the downstream. The problem is that the ecm uses one to test the other. But the codes are heater resistance codes. I would plug in an OBD clear them, see which one comes back first and replace that o2 sensor. Read this on my blog too about those codes
