Possible Causes of P1189 CHRYSLER Code
The P1189 code is related to the Throttle Intake Pressure (TIP) sensor on CHRYSLER vehicles. Potential causes include:
- Faulty TIP Sensor:
The sensor itself may be malfunctioning or providing incorrect readings. - Damaged Wiring Harness:
The wiring associated with the sensor may be open, frayed, or short-circuited. - Poor Electrical Connection:
The connectors in the TIP sensor circuit may be loose, corroded, or damaged (broken, bent, or pushed-in pins).
How to Fix P1189 CHRYSLER Code?
To resolve this issue, follow these steps:
- Check Possible Causes:
Start by examining the points mentioned above. - Visual Inspection:
Thoroughly inspect the wiring harness and connectors associated with the TIP sensor.
Look for signs of wear or damage (exposed wires, corroded connectors, broken or bent pins). - Testing and Replacement:
- Test the Throttle Intake Pressure sensor to confirm it is functioning correctly.
- Replace the sensor or damaged wiring if necessary.
- Ensure all connections are clean and securely fastened.
Possible Symptoms
A malfunctioning TIP sensor may manifest as:
- Check Engine Light On:
The check engine light (or warning indicator) is activated. - Irregular Engine Operation:
The engine may misfire or behave abnormally due to improper air intake management.
Meaning of P1189 CHRYSLER Code
The Powertrain Control Module (PCM) continuously monitors the signal from the Throttle Intake Pressure (TIP) sensor.
When the PCM detects an abnormally low signal, it records the P1189 code to indicate a failure in the throttle air intake system.
This code thus indicates that the vehicle is experiencing a problem with reading or transmitting information from the TIP sensor, requiring inspection and intervention on the relevant circuit.
