P1382 — 9 documented meanings by make

P1382 does not mean the same thing on every car — manufacturers reuse the number for different faults. 13 makes document it: Audi, Chevrolet (Daewoo), Citroen, Ford, Honda, Isuzu, Mazda, Opel / Vauxhall, Peugeot, Saab, SEAT, Skoda, Volkswagen. Find your make below.

P1382 on Audi, SEAT, Skoda, Volkswagen

On Audi, SEAT, Skoda, Volkswagen vehicles P1382 is documented as: Cylinder 16 misfire detected. P1382 points at engine misfire (cylinder 16). The standard definition names the system involved; which part inside it has actually failed is what the checks below establish, cheapest first.

Usually one of: Worn or fouled spark plugs; Failed ignition coil on that cylinder; Injector blocked or leaking; Loss of compression — worn valve or head gasket; Unmetered air leaking into the intake.

Check first, cheapest first:

1. Swap the coil with a neighbouring cylinder and see whether the misfire follows it — this identifies a coil fault in minutes and costs nothing
2. Pull the plug on that cylinder and read its condition
3. Swap the injector the same way if the misfire stayed put
4. Check for vacuum leaks around the intake
5. Compression-test the cylinder if the electrical and fuel sides are both good

P1382 on Chevrolet (Daewoo)

On Chevrolet (Daewoo) vehicles P1382 is documented as: Rough road data invalid. P1382 is stored when the ECU sees range or performance on the circuit named in the code. That describes how the circuit is behaving, not which part has failed — the wiring, the connector and the component itself can all produce it, which is why the checks below start with the cheapest.

Usually one of: Sensor reading is inside its electrical range but does not match reality; Contamination or deposits changing what the sensor sees; A mechanical fault upstream that the sensor is correctly reporting; Sensor drifted with age without failing outright.

Check first, cheapest first:

1. Compare the live value against a second sensor or a known-good figure — this code is about plausibility, not a dead circuit
2. Look for the mechanical cause first: leaks, restrictions or wear that would genuinely produce this reading
3. Clean the sensor if it is the type that fouls
4. Check freeze-frame data to see under what conditions it triggered
5. Replace the sensor only after the mechanical side is ruled out

P1382 on Citroen, Peugeot

On Citroen, Peugeot vehicles P1382 is documented as: Variable camshaft timing solenoid 1 circuit. P1382 points at camshaft timing or VVT. The standard definition names the system involved; which part inside it has actually failed is what the checks below establish, cheapest first.

P1382 on Ford

On Ford vehicles P1382 is documented as: Variable cam timing solenoid circuit fault. P1382 is stored when the ECU sees malfunction on camshaft timing or VVT. That describes how the circuit is behaving, not which part has failed — the wiring, the connector and the component itself can all produce it, which is why the checks below start with the cheapest.

Usually one of: Wiring or connector fault in the circuit; Component failed electrically; Supply or ground problem feeding the circuit; Controlling module fault, though this is the least common of the four.

Check first, cheapest first:

1. Read all stored codes — a general fault code is often the symptom of a more specific one
2. Inspect the connector and wiring for the named component
3. Check supply and ground at the component
4. Measure the component against specification
5. Replace the component once wiring and supply are ruled out

P1382 on Honda

On Honda vehicles P1382 is documented as: Cylinder position sensor, no signal, glow plug relay positioner, short circuit to positive. P1382 is stored when the ECU sees short to positive on the circuit named in the code. That describes how the circuit is behaving, not which part has failed — the wiring, the connector and the component itself can all produce it, which is why the checks below start with the cheapest.

Usually one of: Signal wire touching a permanently live wire in a damaged loom; Connector pins bridged by corrosion or a bent terminal; Internal fault in the component shorting the signal to supply; Incorrect wiring after an aftermarket accessory was fitted.

Check first, cheapest first:

1. Disconnect the component and check whether the signal line still reads battery voltage
2. Inspect the loom for melted or rubbed insulation, especially near heat sources
3. Check the connector for a pushed-back or bent terminal
4. Trace the signal wire back to the module, looking for a live wire running alongside
5. Repair the harness, or replace the component if it is shorting internally

P1382 on Isuzu

On Isuzu vehicles P1382 is documented as: Cylinder position sensor, no signal. P1382 is stored when the ECU sees no signal on the circuit named in the code. That describes how the circuit is behaving, not which part has failed — the wiring, the connector and the component itself can all produce it, which is why the checks below start with the cheapest.

Usually one of: Module has no power or no ground; Broken bus wire or a bad splice in the network; The module itself has failed; Terminating resistor or bus fault taking the network down.

Check first, cheapest first:

1. Check power and ground at the module before suspecting the module itself
2. Read whether other modules on the same bus also report faults — that separates a network fault from a single module
3. Inspect connectors at the module and any inline joints
4. Measure bus resistance across the two lines at the diagnostic socket
5. Replace the module last, once supply and network are proven good

P1382 on Mazda

On Mazda vehicles P1382 is documented as: Camshaft position timing solenoid nr. 1 circuit. P1382 points at camshaft timing or VVT. The standard definition names the system involved; which part inside it has actually failed is what the checks below establish, cheapest first.

P1382 on Opel / Vauxhall

On Opel / Vauxhall vehicles P1382 is documented as: Random or multiple cylinder misfire in gasoline mode detected. P1382 points at engine misfire. The standard definition names the system involved; which part inside it has actually failed is what the checks below establish, cheapest first.

Usually one of: Worn or fouled spark plugs; Failed ignition coil on that cylinder; Injector blocked or leaking; Loss of compression — worn valve or head gasket; Unmetered air leaking into the intake.

Check first, cheapest first:

1. Swap the coil with a neighbouring cylinder and see whether the misfire follows it — this identifies a coil fault in minutes and costs nothing

P1382 on Saab

On Saab vehicles P1382 is documented as: Glow control unit, short circuit to ground. P1382 is stored when the ECU sees short to ground on control module. That describes how the circuit is behaving, not which part has failed — the wiring, the connector and the component itself can all produce it, which is why the checks below start with the cheapest.

Usually one of: Wiring insulation chafed through where the loom passes a bracket or edge; Water or salt in a connector bridging the signal pin to the body; The component itself shorted internally; A harness pinched during earlier repair work.

Check first, cheapest first:

1. Unplug the component and re-read the code — if it changes, the fault is in the component, not the wiring
2. Inspect the loom where it passes metal edges, brackets and hinges
3. Open the connector and check for green corrosion or moisture
4. Measure resistance from the signal pin to a body ground; near-zero confirms the short
5. Repair the harness section, or replace the component if it shorted internally

Which one is yours

A generic OBD reader gives you the number, not which of these meanings your manufacturer assigned to it. To get to the specific one:

1. Use a brand-specific scanner — VCDS for VAG, INPA or ISTA for BMW, XENTRY for Mercedes, Forscan for Ford. It shows the manufacturer's own text rather than the generic one.
2. Read all stored codes together — the neighbouring ones usually point at which system is involved and narrow the list.
3. Check freeze-frame data: the RPM, temperature and load at the moment it triggered indicate which system was active.
4. If you have no brand scanner, tell me the make and model below and I will tell you which of these applies to your car.

Code family

P1xxx is manufacturer-specific code (VW/Audi, BMW, Mercedes, Toyota etc. have different meanings for the same code number).

Severity

Manufacturer-specific codes need a brand scanner (VCDS for VAG, INPA for BMW, STAR for Mercedes).

That is what holds for P1382 in general. From here it depends on your engine — tell me which car it is and what it does, and I will give you the steps for it: real procedures, torque figures and diagrams instead of general advice.
