DTC P2135 [L3]: Notes

WARNING: This page is about a different car, the 2008 Mazda 5. However, it is still accessible from the selected car via links, so may be relevant.

DTC P2135 [L3] DETECTION CONDITIONS AND POSSIBLE CAUSES

DTC P2135	TP sensor No.1/No.2 voltage problem
DETECTION CONDITION	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. Diagnostic support note This is a continuous monitor (CCM). MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	TP sensor No.1 malfunction TP sensor No.2 malfunction Connector or terminal malfunction PCM malfunction

DTC P2135

TP sensor No.1/No.2 voltage problem

DETECTION CONDITION

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.

Diagnostic support note

This is a continuous monitor (CCM).
MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
FREEZE FRAME DATA is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

TP sensor No.1 malfunction
TP sensor No.2 malfunction
Connector or terminal malfunction
PCM malfunction
