DTC Code P1195 – What does this code mean?

<ul> <li><b>Engine Light ON</b>: The Engine Light or Service Engine Soon Warning Light illuminates, indicating a problem with the Electronic Throttle System. This is often the first sign of an issue.</li> <li><b>Reduced Engine Power</b>: The vehicle may enter a 'limp home' mode, significantly reducing engine power to prevent further damage. This is a direct result of the Electronic Throttle System not functioning correctly.</li> <li><b>Delayed Throttle Response</b>: There may be a noticeable delay in throttle response when pressing the accelerator pedal. This delay is due to the system's inability to follow the target throttle position accurately.</li> <li><b>Unstable Idle</b>: The engine may experience an unstable idle, fluctuating RPMs, or stalling. This is caused by the Electronic Throttle System's failure to maintain a consistent throttle position.</li> </ul>

<ul><li>The Electronic Throttle System (ETS) motor may be malfunctioning, leading to improper throttle response.</li><li>Issues within the Electronic Throttle System (ETS) itself can cause delays in target following.</li><li>The ETS unit might be defective, affecting the overall throttle control.</li><li>An open or shorted harness in the ETS can disrupt the communication and functionality of the system.</li><li>Poor electrical connections in the ETS circuit can lead to intermittent or failed throttle responses.</li></ul>

<ul> <li><b>Initial Scan</b>: Use an OBD-II scanner to confirm the presence of DTC P1195 and check for any additional codes.</li> <li><b>Visual Inspection</b>: Inspect the throttle body, wiring, and connectors for any visible damage or corrosion.</li> <li><b>Throttle Body Cleaning</b>: Clean the throttle body to remove any carbon buildup that may be causing the delay in target following.</li> <li><b>Check Throttle Position Sensor (TPS)</b>: Test the TPS for proper operation using a multimeter. Ensure the sensor is providing accurate readings.</li> <li><b>Inspect Electronic Throttle Control (ETC) Motor</b>: Verify the ETC motor is functioning correctly. Check for any signs of wear or failure.</li> <li><b>Examine Power and Ground Circuits</b>: Ensure the power and ground circuits to the throttle body and ETC motor are intact and providing proper voltage.</li> <li><b>Check for Software Updates</b>: Consult the manufacturer’s service bulletins for any software updates that may address this issue.</li> <li><b>Perform Throttle Body Relearn Procedure</b>: If applicable, perform a throttle body relearn procedure to reset the system parameters.</li> <li><b>Test Drive</b>: Conduct a test drive to ensure the issue is resolved and the DTC P1195 does not reappear.</li></ul>

<p>The DTC code P1195 indicates an issue with the Electronic Throttle System, specifically a delay in target following. This is a critical issue as it can severely impact the vehicle's drivability and safety.</p><ul><li><b>Immediate Actions:</b> Inspect the throttle body, wiring, and connectors for faults.</li><li>Check for any software updates or reprogramming needs.</li><li>Address any mechanical obstructions or sensor malfunctions.</li></ul><p>Delaying repair can lead to loss of throttle control, posing significant safety risks.</p>
