replace the o2 sensor but still the same problem
same error code 21 comes on ...? the new sensor is denso,diagnostics now showed normal - LEAN,RICH and changing,the old one showed LAZY,so i think the new one is working fine,but the error comes on. the only different between the old one and the new one is resistance - old one shows 7,the new one shows 10 ohm! please help This post has been edited by EdinR-DrugB: Apr 8, 2015 - 12:11 AM |
