Understand the car, don't just erase mistakes.
The information is general and does not replace professional consultation. Code P0123 is a diagnostic signal from the PCM indicating that the voltage in the throttle position sensor circuit exceeds…
When the Check Engine light illuminates on the dashboard and the scanner shows code P0130, many immediately think: “oxygen sensor problem.” But this is just the tip of the iceberg.…
Code P0340 appears when the engine control module (ECM) detects a malfunction in the camshaft position sensor (CMP) circuit. The sensor transmits the current camshaft position signal, which the ECM…
Has code P1320 appeared on your dashboard, and is the engine behaving oddly? Let’s explore what happens inside the engine management system when the ECM registers this fault. P1320 is…
DTC P0122 means “Throttle Position Sensor A Circuit Low Input.” The ECM records this when the TPS voltage drops below 0.17–0.2 V instead of the expected 0.5–4.5 V. This can…
The information is general and does not replace professional consultation. Code P0102 indicates a low signal level from the mass air flow sensor (MAF). This page provides a quick action…
This guide covers common P0100 causes and checks. Exact test values and repair steps depend on the vehicle, engine, and service information. Code P0100 is a diagnostic trouble code (DTC)…
The P0335 code appears when the engine control module detects a missing or distorted signal from the crankshaft position sensor. Without this signal, the ECM cannot synchronize ignition and fuel…
Code P1800 is a manufacturer-specific DTC interpreted differently by various automakers. Most commonly, it relates to the intake system flap control circuit (VIAS, IMRC) or a valve hydraulic actuator. Below…
P0141 – oxygen sensor heater circuit malfunction Bank 1 Sensor 2 (post-catalyst). Four main causes: faulty sensor heater, damaged wiring or connector, blown fuse, and less commonly, PCM/ECM failure. Basic…
