How to solve the P1297 trouble code?

[RyanDella]

P1297 trouble code causes and solutions are as follows: 1. The P1297 trouble code means the electric load sensor circuit voltage is too low. When the vehicle's charging system load increases due to car lighting or rear window heating, it can send an electronic signal to the ECU to control idle speed and resolve the issue. 2. P1297 can also indicate a pressure difference between the exhaust turbocharger and throttle valve. This fault may be caused by throttle valve damage, which can be resolved by inspecting and replacing the throttle valve. Here is some extended information: 1. During vehicle operation, component aging, damage, missing parts, or functional abnormalities are inevitable. When the components don't match the information stored in the control unit, specific trouble codes are generated within the control unit. These codes are translated into professional terms familiar to technicians through specialized diagnostic tools, while also providing important data streams at the time of the fault. 2. Trouble codes are stored in registers for easy reading and analysis, and can also alert drivers through instrument displays or warning sounds.
