Trouble code P1111 means: IAT Sensor Circuit Intermittent Voltage High
Trouble code P1111 means: System Pass
The code P1111 for a 2004 Jaguar X-Type typically indicates an issue with the intake air temperature sensor. This code can result from a faulty sensor, poor electrical connections, or issues with the engine control unit (ECU). It's advisable to inspect the sensor and its wiring, and if necessary, replace the sensor to resolve the issue. Always consult a professional for accurate diagnosis and repairs.
fauit code p1111
The code P1111 for a 2004 Jaguar X-Type typically indicates an issue related to the vehicle's air intake system, specifically the throttle position sensor or the air intake temperature sensor. This can result in poor engine performance or increased emissions. It's advisable to have the vehicle diagnosed with a professional scan tool to pinpoint the exact cause and make necessary repairs.
The P0420 code indicates a problem with the catalytic converter's efficiency, suggesting that it may not be functioning properly and could require replacement or inspection. The P1111 code typically relates to the engine control module detecting an issue with the air-fuel mixture or sensor readings, often linked to the mass airflow sensor or fuel system. Together, these codes may point to issues affecting emissions and engine performance, necessitating diagnostics to pinpoint the exact causes.

I just came in from the cold, fixing the same problem you are talking about (P0113). My 3.4L V6 01 Alero was hard shifting with the Service Engine light on. The Diagnostic Trouble Code was P0113: Intake Air Temperature Circut, High Input. The Trouble Code P1111 is a similar problem: Intake Air Temperature sensor circut intermittent high voltage. Hoping for the easy fix I bought and installed a new IAT sensor (AKA: Air Charge Sensor) at AutoZone for $13.99, but it didn't help anything. The problem was the wiring leading to the sensor had broken. The IAT sensor shares the same 5V reference voltage with the Coolant Sensor and the Throttle Position Sensor. When the wire broke at the IAT Sensor, the TPS signal got messed up telling the computer to up the transmission pressure to "protect" the transmission. (Even though it felt like it was destroying the transmission shifting that hard) The solution to the problem was to order a new IAT Sensor connector pigtail, GM Part #12102620/ AC Delco Part #PT307/ PICO Part #5616. I found mine at bmotorsports.com for under $8.00 after shipping. Stagger your cuts on the pigtail wires, heat shrink both butt connectors, and re-apply some electrical tape and you'll be back to smooth shifting in no-time!
This p-code is pointing to Oxygen Sensor Bank 2 Sensor 2
The speed sensor tells how fast the wheels are turning. The cruise control uses this to maintain the speed. When you get the code for speed sensor it is not working properly.
A code 10 is a Iat sensor. Intake air tempature sensor.
