What is P1004 : Engine Error code Causes Explained
The P1004 engine trouble number indicates a camshaft position or timing issue. Understanding its causes, risks, and treatments is essential for sustaining performance, minimizing severe damage, and running your vehicle smoothly.
How to Identify a DTCs Number
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
Identifying a DTC’s number, like P1004, is done using an OBD-II scanner that connects to your vehicle’s diagnostic port. The scanner communicates with the ECM, retrieves stored trouble codes, and displays the specific DTC number, which helps in diagnosing the exact issue.
