What does the p2303 code on a PCM mean?
This high voltage surge creates a flyback voltage which the PCM uses as a feedback during the ignition diagnostics. The PCM continuously monitors the ignition system for concerns. The P2303 code sets when the PCM detects a short to voltage in the circuit. Need more information on how to fix the P2303 code?
What are the symptoms of a PCM fault?
Like other PCM fault symptoms, this issue will also be intermittent. There are many reasons that cause the vehicle to fail to start when the ECU begins to fail but the most common symptoms are displayed in relation to the fuel injectors and spark plugs.
How does the PCM receive the battery voltage?
ADDITIONAL NOTES PCM receives battery voltage (B+) through a fuse or fusible link. Check for an open circuit. An open ground or power (B+) circuit on a fuel-injected engine removes power from the ECM and prevents the engine from starting.
How to find out if your car has a p2303 code?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost of diagnosing the P2303 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city.
What does it mean when your car has a code P2302?
Anecdotally this code is most commonly found on Jeep and Dodge vehicles though. If your vehicle has stored a code P2302, accompanied by a malfunction indicator lamp (MIL), it means that the powertrain control module (PCM) has detected an abnormal voltage condition in the secondary control circuit of the ignition coil designated with the letter A.
How did the u0100 lose communication with the PCM?
U0100 Lost Communication with Powertrain Control Module (PCM) – Bus messages not received from the Powertrain Control Module (PCM) for approximately two five seconds. With the ignition on. Battery voltage between 10 and 16 Volts. Ignition Off Draw (IOD) fused installed.
Can a P2302 be repaired by a maintenance tune up?
The P2302 may be repaired by a maintenance tune up but do your diagnostic work to make sure Have p2302 (secondary ignition) code and engine light still. Have replaced plugs, wires and all coils. Cleared code with my obd2 using 2 different apps. Had AutoZone clear code with theirs also. Light continues to pop up 1 second after start.
