If you drive a Citroen C5 Aircross, a Peugeot, or any vehicle equipped with the 2.0L diesel engine, experiencing a sudden loss of power or engine "juttering" can be alarming. Often, these symptoms—combined with a dashboard warning light—point to a specific culprit: the P0113 Diagnostic Trouble Code (DTC).
In this guide, we break down a real-world repair case from SA Diagnostic's to show you exactly how to identify, locate, and fix this issue using professional methods.
Locating the intake air sensor is the first step in solving power loss issues.
Step 1: Stop Guessing, Start Scanning
Before you pop the hood or start buying parts, you need to confirm the issue. As seen in the tutorial, the technician starts by plugging in a diagnostic machine. Why? Because "losing power" could be anything from a turbo issue to a clogged fuel filter.
To follow along with this repair, you need a tool that can communicate specifically with Peugeot and Citroen systems. The iCarsoft CR ULTRA P is the ideal companion for this task. Unlike basic code readers, the CR ULTRA P provides:
- Full System Access: Read codes from the Engine, Transmission, ABS, and more.
- Live Data Stream: Verify if the sensor is sending erratic voltage before you replace it.
- Manufacturer-Specific Support: Covers over 55 vehicle brands ensuring deep compatibility.

Step 2: The Diagnosis & Fix Process
Once your iCarsoft diagnostic tool confirms the P0113: Inlet Air Temperature Sensor 1 Circuit High error, follow these steps derived from the expert video:
1. Locate the Sensor
On the 2.0L BlueHDi engines found in the C5 Aircross and similar models, the sensor is located on the top air intake pipe. Important: Do not confuse it with the DOX sensor located further down.
2. Check the Wiring
The technician advises: "Check the wiring to make sure you are getting voltage to these." Use a multimeter or the live voltage data on your CR ULTRA P to ensure the wires haven't been chewed by rodents or corroded.
3. The "Clean First" Approach
Before buying a new part, try cleaning the existing one:
- Remove the sensor (it's usually a plug-and-play fitment).
- Spray the element with Electrical Contact Cleaner (available at most auto parts stores).
- Let it dry completely and reinstall.
- Crucial Step: Use the iCarsoft CR ULTRA P to clear the fault codes.
If the code stays away after a test drive, you've saved money! If the check engine light returns, proceed to replacement.
Using live data to verify sensor performance ensures accurate repairs.4. Use OEM Parts Only
This is a critical tip from the video. Cheap aftermarket sensors often fail to communicate correctly with the sensitive ECUs in modern French cars. Stick to Original Equipment Manufacturer (OEM) sensors to avoid "hassle and stress."
Why Accurate Diagnostics Matter
Modern vehicles rely on precise data. A P0113 code affects how much fuel your engine injects. Ignoring it can lead to clogged DPFs (Diesel Particulate Filters) and reduced engine life.
Equipping yourself with professional-grade tools like the CR ULTRA P empowers you to perform these checks at home, potentially saving hundreds in labor costs. Whether you are maintaining a family fleet or running a workshop, knowing exactly what's wrong is half the battle.

Frequently Asked Questions (FAQ)
Can I drive my car with a P0113 code?
While you can often drive for short distances, the car may enter "limp mode," limiting power to protect the engine. It is recommended to diagnose the issue immediately with an OBD2 scanner.
Will the iCarsoft CR ULTRA P work on my specific car?
The CR ULTRA P is a comprehensive diagnostic tablet. It covers over 55 vehicle makes, including Peugeot, Citroen, Ford, BMW, and more, making it versatile for almost any vehicle in your driveway. Check our full vehicle coverage list here.
How do I reset the Check Engine Light after repair?
Disconnecting the battery is not the recommended method as it can reset radio codes and seat memories. The correct method is to use the "Erase Codes" function on your diagnostic tool after the repair is verified.
