How to Fix Azlk Moskvich P0957
Diagnostic Steps:
Regarding P0957, carefully inspect the wire harness near the intake manifold bracket, best accessed from below near the oil filter. Look for chafing, pinching, or damaged insulation.
Repair Solution:
Brake switch circuit concerns may involve open or shorted BPP circuits, damaged switches, or misadjustment. Verify stoplight function and follow proper self-test procedures per service manual.
Technical Notes:
P0957 DTC indicating a sensor fault does not always mean the sensor itself is bad. The issue may stem from the systems being monitored or even the sensor wiring. Proper diagnosis is essential.
Azlk Moskvich P0957 Repair Cost
Ground circuit repairs on the Azlk Moskvich — a common cause of P0957 — are labour-intensive but parts are cheap. Expect 1.5–2.5 hours of labour ($120–$200) to clean, treat, and re-torque all engine and transmission ground straps. This is excellent value given how often it resolves persistent fault codes.
P0957 Description
P0957 engine trouble code is related to Shift/Timing Solenoid Malfunction.
Main Cause
The primary reason for P0957 OBD-II Engine Trouble Code is: Injector Circuit Malfunction - Cylinders.
Common P0957 Misdiagnosis on the Azlk Moskvich
Fuel injector replacement is over-prescribed on the Azlk Moskvich for P0957 when the actual fault is a weak fuel pump. Low fuel rail pressure causes lean misfire that looks identical to injector failure in static scan data without a live fuel pressure test.
DIY Repair Guide: P0957 on Azlk Moskvich
After any repair that involved disconnecting the battery on the Azlk Moskvich, the power window, steering angle sensor, and transmission adaptive values all require a reset drive cycle. Skipping this can cause false fault codes — including P0957 — for the first two to three start cycles.
Preventing P0957 on the Azlk Moskvich
For Azlk Moskvich owners in high-humidity climates, applying electrical contact cleaner and dielectric grease to the ECU connector pins every two years prevents the corrosion-related signal errors that register as P0957.
Frequently Asked Questions — Azlk Moskvich P0957
A: Yes. A weak battery causes voltage drop during cranking that confuses the ECU and can store a range of fault codes. Always rule out battery and charging system health before diagnosing sensor-related codes.
