C1538 Volkswagen Touran I OBD Code

OBD/2 C1538 error code description and symptoms.

Throttle Position (TP) Sensor Intermittent The TP sensor circuit is monitored by the PCM for sudden TP rotation angle (or voltage) input change through the comprehensive component monitor (CCM). If during the last 80 warm-up cycles in key ON engine running the PCM detects a TP rotation angle (or voltage) changes beyond the minimum or maximum calibrated limit, a continuous diagnostic trouble code (DTC) is stored. Poor continuity through the TP sensor connectors Poor continuity through the TP harness Intermittent open or short inside the TP sensor While accessing the TP V PID on the scan tool, lightly tap on the TP sensor or wiggle the TP sensor connector and harness.

Circuit High Input codes like C1538 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

C1538 Volkswagen Touran I Error Code Repair Process :

If your scp (j1850) invalid or missing data for mirrors check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system C1538 and engine control unit are in charge of monitoring a bunch of different scp (j1850) invalid or missing data for mirrors, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Volkswagen Touran I C1538 OBD2 Code

A common cause of code C1538 is the failure of SCP (J1850) Invalid or Missing Data for Mirrors, but there are several other possible causes as well, such as ;

Damaged VCT phaser
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Fuel injectors may be faulty
Foreign matter caught in fuel filler cap

C1538 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
