I am looking at buying a 98 ford ranger 5speed under 100k miles seems to run fine engine light was on so I took it past the local parts store to get the codes

p0133-o2 sensor slow response bank 1 sensor 1
p0141-heated o2 sensor bank 1 sensor 2
p0135-heated o2 sensor bank 2 sensor 1
p1400-egr curcit low voltage presure sensor low voltege

At a glance it looked to me like the egr/sensor could be causing all of these codes
has anyone had a simalar combination of codes or have any sugestions as to the cause of them

Thanks for the help

 

Well I guess it was not the truck for me it sold right after I posted this of course
