Subject: Re: Help Appreciated - Service ASR by Matatk on 2011/3/19 2:52:44 As far as the trouble codes: http://tech.corvettecentral.com/2011/ ... diagnostic-trouble-codes/ "H" represents a history code, and may or may not be current. 64 Bank 2 (Right Front) Heated Oxygen Sensor (HO2S) #1 Circuit (Lean Exhaust Indicated) 65 Bank 2 (Right Front) Heated Oxygen Sensor (HO2S) #t Circuit (Rich Exhaust Indicated) 72 Vehicle Speed Sensor Loss The O2 sensor problem sounds like a bad sensor or wiring since it is throwing both codes. The VSS loss I'm not familiar with, but sounds like a wiring issue, as well. The VSS is located on the side of the transmission, driver's side. You said you serviced the throttle body? What do you mean by that? As in you removed it? Left it on and cleaned it? Most sensors are sensitive to TB cleaner. Did you possibly spray the TPS with cleaner? I would check the TPS voltage with an ohmmeter to see what it registers, closed and open. Also, the ASR is connected to the throttle body, so I'm not sure if there is a reset procedure if the cable has been moved/position changed. If I give you suggestions on what to check first, I'm just making semi-educated guesses. Without a FSM for a 96 I personally can't tell you the correct troublshooting steps. Someone with a 96 (or 90+) will have to jump in. Good luck, Matthew |
