Frequently Asked Questions about P1187 Chrysler Code
1. What does OBDII code P1187 mean on a Chrysler vehicle?
P1187 indicates a correlation issue between the throttle inlet pressure sensor and the manifold absolute pressure (MAP) sensor, suggesting inconsistent or unexpected readings.
2. What are the common symptoms of code P1187 in a Chrysler?
Symptoms may include poor engine performance, reduced fuel efficiency, rough idling, hesitation during acceleration, and illuminated check engine light.
3. What causes the P1187 code to appear in a Chrysler?
Common causes include a malfunctioning MAP sensor, a faulty throttle inlet pressure sensor, wiring issues, vacuum leaks, or a problem with the powertrain control module (PCM).
4. Can a dirty throttle body cause the P1187 code?
Yes, a dirty or clogged throttle body can disrupt airflow readings, leading to a mismatch between the throttle inlet pressure and MAP sensor data.
5. How is the P1187 code diagnosed in a Chrysler?
A mechanic will use a scan tool to read live data, check the MAP and throttle inlet pressure sensor readings, inspect wiring and connectors, and look for vacuum leaks.
6. Is it safe to drive with the P1187 code on a Chrysler?
Driving with this code is not recommended, as it can lead to reduced performance and potentially cause further damage to the engine or sensors.
7. How do you fix the P1187 code on a Chrysler vehicle?
Repairs may include replacing a faulty MAP sensor or throttle inlet pressure sensor, repairing damaged wiring, cleaning the throttle body, or reprogramming the PCM if needed.
8. Can a vacuum leak trigger the P1187 code in a Chrysler?
Yes, a vacuum leak can cause incorrect pressure readings, leading to a correlation error between the throttle inlet pressure and MAP sensor.
9. How much does it cost to repair the P1187 code on a Chrysler?
Repair costs vary but may range from $150 to $400 depending on whether sensors, wiring, or other components need replacement or repair.
10. Will clearing the P1187 code solve the problem on a Chrysler?
Clearing the code may temporarily turn off the check engine light, but the underlying issue causing the code must be addressed to prevent it from returning.
