Scanned error codes - 1999 Z3 2.8

[mksp4747]

Hi al!
My Z is due for inspection and the dreaded check engine light is on. Ran the scanner and it comes up with 5 codes.
First two are codes 25 and 55, Lambda Sensor Heater -Bank 1 - O2 sensor and Lambda Sensor Heater -Bank 2 – O2 Sensor.
I recently replaced both pre-cat O2 sensors and while it cleared the original fault, it now comes up with these two.
Also, when I looked at the sensor cables, the feed cable going to bank 2 sensor was not fed correctly and laid up against the engine and melted some of the wire insulation, down to bare wire....#1 was fine. Replaced both sensors...probably needed it with 177K miles and I have no idea if they were ever replaced.
Not I get these sensor heater errors. Ideas?

The other 3 look like they may be related, they come up in order, 50, 35 and 126:
50: EVAP Control Valve or Response Monitoring Level 2
35: Aux. Air Injection System Relay
126: Activation Tank Leak Pump Solenoid
Any thoughts on these error codes? is one causing the others or?

Reset codes after O2 sensors replaced pre-cat.
Also, repaired the cable running to bank #2 sensor.
The code errors came in after the above was done. Drove it several times and re-read codes. Cleared and read again, The error codes I listed above were read after all of this.

Have you actually cleared the codes to see which come back?

Replace F204 and retest.

Randy, what is an F204?

[rf900rkw]

Fuse F204. It's in the DME box inside the holder. Break the holder open and replace the 30A fuse, the one that's blown.

Thanks Randy!
Sorry for my late response, been away on business. I will check that out. I was beginning to think I may have blown a fuse given the exposed wiring on pre-cat bank 2 O2 sensor.
So hopefully this is it, sure sounds like it!
I appreciate the help!!

You may be better off starting a new thread with your problem rather than tackiing on to a thread that died four years ago.
