I broke my water temp sensor while changing the cap and rotor ... ...meanwhile, I got a check engine light with codes 4 and 5 ... I replaced the broken sensor with one from Rock Auto and cleared the codes... but -the check engine lite is still on , and now I still get a code 4 .... I've had the van for 13 years with NO check engine lites-- QUESTION ... could the new sensor be bad ??? ( If it matters, my temp. guage is working properly...does the guage run off of that sensor??) thanks !! - Phil
