Hi to all,
Iv just done some checks as having a bit of trouble with 95 wrx import,and i got two codes flash up 1 being 21 which i looked up and found it engine coolant temp sensor,dont no why that would be as car do not over heat and coolant gauge reads ok,and the second code is 23 which i beleave to be the Maf.

Could someone please comferm these are correct before i go spending my dose on something it aint.

Many thanks to all,
Karl.

 

Codes are correct.

Coolant temp sensor doesn't mean the car will overheat just means the ecu doesn't get the correct reading and normally causes fluctuating idle and problems starting from cold it is relatively cheap and easy to replace

 

Much cheaper than the MAF sensor!!
Change your coolant sensor then clean your MAF. Once that's sorted, clear your fault codes and see where you're at.....

 

Cleaned me Maf today,but got to dark to put back on,but will do to morra,it was'nt that dirty so may need replaceing,shall have a look at the coolant sensor to morra and see whats what.
Cheers for the help guys.

Hi,had a look at where the coolant sensor is,think it may be easyer to do while iv got the MAF and pipe work of and out of the way.
Did you remove anything to do the cooland sensor....?
