first, my car.. '89 civic hatch. SOHC ZC (d16a6) 5 spd. ok, im throwing code 63 and the car seems to be misfiring. code 63 is (i looked it up): o2 sensor heated i recently put an exhaust on my car.. a cheap E-bay 4-2-1 header and a Monza Pacesetter cat-back system. the Monza kit has a lot of backpressure, could this extra backpressure cause an increase in exhaust temp's to cause my 2 month old o2 sensor to get 'heated'? is there any way around this problem? (i.e.: a high-temp o2 sensor) i dont want to have to get rid of the exhaust, especially after the money I put into the kit. thanks in advance
ok.. i might have been wrong about it being code 63... this is what code 63 says.. : 63- Accord Civic CRV CRX Del Sol Odyssey Prelude 96-98 96-98 97-98 n/a 96-97 96-98 96-98 Oxygen Sensor, Heated - Sensor 2 (Secondary) high voltage, low voltage, or slow response my car (and ECU) is an '89 civic.. and i only have a 1-wire O2 sensor which would mean its a non-heated O2 sensor. I was thinking the code meant the O2 sensor was heated, as in overheated or burnt. the light on the ECu flashes 6 times, then takes a VERY short break then flashes 3 times. that means 63 i believe. if not, then it means code 6 and code 3. or code 9 code 6: 6- Accord Civic CRV CRX Del Sol Odyssey Prelude 85-98 86-98 97-98 85-91 93-97 95-98 85-98 ECT Sensor (Engine Coolant Temperature) defective circuit or unplugged / defective sensor code 3: 3- Accord Civic CRV CRX Del Sol Odyssey Prelude 85-98 86-98 97-98 85-91 93-97 95-98 85-98 MAP Sensor (Manifold Absolute Pressure) defective circuit or unplugged / defective senso code 9: 9*- Accord Civic CRV CRX Del Sol Odyssey Prelude 85-98** 86-98 97-98 85-91 93-97 95-98 85-98 CYP Sensor (Cylinder) defective circuit or unplugged / defective sensor * not a valid code for any throttle body injection Hondas ** not a valid code for V-6 engines GRR! idk. im sure its not code 6, the temp guage is reading out fine. that would also rule out code three, because code 6 & 3 would have to go together in order for the ECU code to make sense. Code 9 is saying its not a valid code for any TBI hondas.. my civic is FI, which means it uses a TB, wouldnt that make it throttle body injected?
