This Week’s Winners
On this edition of Fix of The Week: a programming bug in a Honda, a Toyota running rough, and a wonky transmission in a Pontiac.
2016 Honda Civic – Double A Automotive
The customer returned the day after a tire replacement stating that the TPMS resent light was still on. We performed the reset again, drove 30 minutes at 49mph, turned the vehicle off, and waited 45 seconds. The TPMS light did not flash, indicating it had accepted the calibration. The customer returned the next day due to TPMs low tire warning again, so we called Honda to get some insight. They have a known programming flaw— you have to calibrate 3 times in a row to clear any previous data. We performed the reset 3 times in rapid succession and since then the customer has not had to come back. A little tip: turn the key on to see if the calibration is accepted. After 45 seconds, the TPMS light will illuminate if it’s not.
2004 Toyota RAV4 – Grandma’s Garage
This RAV4 was idling rough when the AC clutch was engaged and when the car was in drive or reverse. The idle drops to 400-500rmp and felt like it was about to stall out. The alternator voltage dropped to 12.5v. In addition, the battery was 4 years old and failed the load test and the alternator was draining. We checked for codes but found none, so we changed battery and alternator. At this point, there was no drain and the battery passed the load test, but we still had the issue with the idle drop when the AC clutch engaged. We hooked up the scan tool to check the MAF reading when the idle dropped, but that didn’t change. We removed the MAF which was filthy. We cleaned the MAF and throttle body and that fixed it.
2006 Pontiac G6 – TGK Automotive
The car moved in reverse fine but would not move in any forward gear positions. The transmission pan was removed to inspect the condition of the Forward Clutch, Low, and Reverse Band metal fluid/lube pipelines that sit just above the filter. The Lube/fluid pipeline assembly was replaced along with a new filter, pan gasket, and fluid. A test drive confirmed the transmission worked correctly.
