Can’t diagnose CEL & Coolant Temp Light
 

I’ve got a CEL for the following:

P1124 P1126 with P0130 P0150 P0115 marked as pending in my OBD II Reader

On top of that I have the quick blink for the engine temp sensor on my water temp gauge.

Really I am perplexed, coolant is topped off and no visible sign of any leaks and car runs as expected. I got the car for a steal a few days ago and went in expecting a few thousand in repair. Other issues are the wipers not working and the air con not blowing cold air.

If I clear the CEL it stays off for atleast a day, tends to come back on if I idle for a while.

Any people smarter than me who can weigh in? I’ve tried to research it on here and some other forums but everybody seems to have slightly different codes. I’m planning to change out the spark plugs and coils and clean the MAF this week is it worth throwing in the two pre car O2 sensors or should I just assume the worst and prepare for a costly exhaust overhaul?

Thank you!

Always helps to know the year and model for this kind of thing.

P1124 - Bank #1 overly lean
P1126 - Bank #2 overly lean
P0130 - Bank #1 O2 sensor ahead of main cat shorted.
P0150 - Bank #2 O2 sensor ahead of main cat shorted
P0115 - Coolant sensor signal implausible

Looks like you have wiring harness problems at a minimum......................

Sorry about that it’s a 1998!

Then the information I gave you is correct.

Good luck.
