Question Asked: Why does the DTC P0123 for "TPS voltage high" come on when I turn on the A/C?
June 27, 2014, 11:35 AM
I have changed the TPS with a new one and cables/connections look and test fine. I cleared the code, the problem still occurs but only when turning on the a/c. The a/c compressor works fine. The a/c system has a low charge but no trouble code shows for same. No other trouble codes are stored or show when the vehicle is run without a/c.
