| : Help with Check Engine Light ppowers2 03-15-2011, 10:05 AM Please help, 2008 Highlander with 32000 miles, MIL light just came on with one DTC P2192 (system to rich at higher loads). Has anyone come across this code? Any help would be appreciated. Vehicle seems to run fine with no drivability problems. Cleared code but it came bach the next day. Dealer said to check the gas cap, but it seems fine. avconsult 03-15-2011, 09:20 PM An ODBII scan tool with logging is required to diagnose further, but some possible causes: 1. Dirty MAF 2. Faulty TPS 3. Faulty A/F upstream sensor 4. Faulty downstream (after catalytic) 02 sensor alotawatts 03-30-2011, 07:43 PM Dealer said to check the gas cap, but it seems fine. 'Seems' ? I replaced the gas cap on my 2000 Camry today because of .....CEL - EVAP codes. $8. for an after market cap. Cheap fix. The second cap replacement for this car with aprox 70,000 miles ! Your problem (code) sounds different though. | |
