Dtc P2135[L3 With Tc] - Mazda CX-7 2007 Workshop Manual

DTC P2135[L3 WITH TC]

DTC P2135 TP sensor No.1/No.2 voltage correlation problem
• The PCM compares the input voltage from TP sensor No.1 with the input voltage from TP sensor No.2
when the engine is running. If the difference is more than the specification, the PCM determines that there
is a TP sensor No.1/No.2 voltage correlation problem.
