General Decoding Information This topic can be somewhat confusing, especially with the amount of information available and the interpretation of it. You can decode the casting number. And you can check dates. The engine code and partial vin will accurately nail down whatever the thing is rather quickly, and the other information will fall into line with that. If you already know what you're doing, Chevy Engine Codes are listed down below. Let's decode something real quick like, you can read the details further down below: Here's an engine.

I know Norwood built Camaros - among other things. So I'm dealing with something from a Camaro. Now to the engine code. V flint, january 12th CLJ in is a horsepower used in a Z28 Camaro mated to a manual transmission. If that happens to be the vehicle this engine is currently sitting in they "match". I'm Done. CTG - in My point here I guess is It's a If you're trying to buy a and you see this thing laying on the ground, then there it is. Once you identify something - like the above vette block, then you can conclude what other pieces and parts should have been on it, and check those casting 's.

Take the above CLJ example. In CLJ is a L69 in a monte carlo, or in it's a from a monte carlo. So when the arguement overor comes up That eliminates the and possibilities. This is why I looked at the VIN code 1st.

Everything else lines up and there's no confusion. Engine Code Stamping Numbers All engines are stamped with an engine ID code, consisting of assembly plant code, production date and suffix code. The location of this code depends on the type of engine, typically as follows: Small Block Chevy : Machined pad in front of the passenger side cylinder head. Often hidden by the alterator. Big Block Chevy : Machined pad in front of the passenger side cylinder head or above timing chain cover.

Six Cylinder : Passenger side of the block behind the distributor. The engine assembly date must precede the car build date often by a few daysotherwise something is amiss. Some engine machining operations decking will obliterate the engine ID. The format consists of divisional identification number, model year, assembly plant designation and vehicle serial or sequence number.

In model cars, the serial VIN number of the car the engine was installed in is stamped next to, or under the engine code ID. Starting inthe serial number is stamped either above the oil filter, somewhere on the block pad in front of the cylinder heador on the transmission flange somewhere.The actual list of available parameters is vehicle specific.

Each sensor is characterised by a number called PID Parameter Identifier used to identify the parameter.

For example, the standard stipulates that the engine speed has a PID of As for the modes, not all cars support all PIDs. This mode gives the freeze frame or instantaneous data of a fault. When a fault is detected by the ECM, it records the sensor data at a specific moment when the fault appears. This mode shows the stored diagnostic trouble codes. These fault codes are standard for all makes of vehicle and are divided into 4 categories:.

Note: mostly it is not necessary to clear a fault that has not been diagnosed or repaired. The MIL will light again during the next driving cycle. It mainly applies only to petrol vehicles. Mode 6 replaces the functions that were available in Mode 5. This mode gives the results of self-diagnostics done on systems not subject to constant surveillance. This mode gives unconfirmed fault codes. It is very useful after a repair to check that the fault code does not reappear without having to do a long test run.

The codes used are identical to those in mode 3. This mode gives the permanent fault codes. The codes used are identical to those in modes 3 and 7.

Unlike modes 3 and 7, these codes cannot be cleared using mode 4. Only several road cycles with no appearance of the problem can clear the fault. The table below describes the main PIDs supported by modes 1 and 2. Mode 1 is used to know the current value of the corresponding PID. Mode 2 is used to know the state of the PIDs when a fault is detected.

None of the vehicles described below support mode 8. Energy column: type of fuel, Die for diesel, Pet for petrol, Hyb for hybrid Vehicles in this list are classified in alphabetical order depending on the make then the model, then in order of increasing power.

If your vehicle is not in the table below, go to the next site also containing a list of vehicles tested. Note, the interface and protocol used as not all are supported by an ELM type interface. Compatible vehicles can be diagnosed using generic multibrand ELM interfaces. We asked the users of our EOBD-Facile software to help create this list by returning their "log" file of the connection to their vehicle.

In exchange for this contribution, the software functions are available for free.

This list of faults, also called DTC for Data Trouble Code has been defined so that any diagnostic device can read and decode them. They have a standard format as shown below:. As the list of generic OBD codes is not always sufficient, manufacturers can add as many of their own codes as they need. The last 3 digits correspond to an incremented number purple digits.

This may be a hexadecimal number i. For P family codes, sub-families have been defined using the 1st digit in this example the "3" :. Below you will find a list of the most commonly used codes.

Codes by family. Description of the standard trouble OBD codes by family Standard or generic fault codes are a list of codes common to all manufacturers. They have a standard format as shown below: The first letter indicates the family of DTC. P : Powertrain, i. The first digit indicates if the code is generic or not green digit : 0 : Generic fault 1 : Manufacturer fault.

Post a comment. Piston app says code iP is: Subsystem- vehicle speed control and idle speed control. Online, the code P says it is oil pressure.

Is Piston using standard codes or their own? Nice app. Didn't have a particular code I was looking for, maybe it's me. PO code not found.All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

Manufacturers also define additional PIDs specific to their vehicles. BeforeJ referred to these services as "modes". They are as follows:. Vehicle manufacturers are not required to support all services. Each manufacturer may define additional services above 9 e. The expected response for each PID is given, along with information on how to translate the response into meaningful data. Note that services 01 and 02 are basically identical, except that service 01 provides current information, whereas service 02 provides a snapshot of the same data taken at the point when the last diagnostic trouble code was set.

If service 02 PID 02 returns zero, then there is no snapshot and all other service 02 data is meaningless. Each bit is numerated from 0 to 7, so 7 is the most significant bit and 0 is the least significant bit See below.

AB is two's complement signed [3]. Service 02 accepts the same PIDs as service 01with the same meaning, but information given is from when the freeze frame [4] was created. Some of the PIDs in the above table cannot be explained with a simple formula. A more elaborate explanation of these data is provided here:. A request for this PID returns 4 bytes of data Big-endian. For example, if the car response is BE1FAit can be decoded like this:.

The first byte A contains two pieces of information. The second, third, and fourth bytes B, C and D give information about the availability and completeness of certain on-board tests. Note that test availability is indicated by set 1 bit and completeness is indicated by reset 0 bit. The third and fourth bytes are to be interpreted differently depending on if the engine is spark ignition e.

Otto or Wankel engines or compression ignition e. Diesel engines. In the second B byte, bit 3 indicates how to interpret the C and D bytes, with 0 being spark Otto or Wankel and 1 set being compression Diesel. A request for this PID returns 4 bytes of data.

The first byte is always zero. The second, third, and fourth bytes give information about the availability and completeness of certain on-board tests. As with PID 01, the third and fourth bytes are to be interpreted differently depending on the ignition type B3 — with 0 being spark and 1 set being compression. Note again that test availability is represented by a set 1 bit and completeness is represented by a reset 0 bit. A request for this PID will return 9 bytes of data.

The first byte is a bit encoded field indicating which EGT sensors are supported:. The remaining bytes are 16 bit integers indicating the temperature in degrees Celsius in the range to Only values for which the corresponding sensor is supported are meaningful. The same structure applies to PID 79but values are for sensors of bank 2. A request for this service returns a list of the DTCs that have been set. The list is encapsulated using the ISO protocol. Three or more DTCs in the list are reported in multiple frames, with the exact count of frames dependent on the communication type and addressing details.
