What do these codes mean? P0705, P0700 and P2135

The codes are likely related and I would bet the P2135 is causing the other codes. Codes such as these for a 2006 Suzuki Forenza typically represent problems with the car. A P0700 code indicates there is a problem with the transmission control system; this could be a system malfunction. A P0705 code usually represents an issue with the transmission range sensor circuit of the car. When contacting a car mechanic about these problems (which is the highly recommended course of action) you should mention these codes to the mechanic; it could make their job a lot easier. • What to do if you have a problem with your car If you find you have a problem with your car, you should firstly assess how serious it could potentially be. If you think it could cause a hazard whilst driving, you should not use the car until a professional mechanic has been consulted. For instance, if you discover you have a flat or popped type, do not drive your car until the type has been refilled or replaced (with problems such as these, driving your car to the garage to be fixed is often an exception to the rules regarding problematic cars). If you only have a minor problem with your car, you should continue to drive it but get the problem sorted out as soon as possible. For instance, you may discover you have a chip in your windscreen. Whilst this is unlikely to cause you any problems in the very near future, you should get it repaired as soon as possible to prevent the chip developing into a crack (which will be troublesome). 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). • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • 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
