What does DTC p1400 mean on a car?
DTC P1400: Cold Start Emission Reduction Control System. Circuit/System Description. The catalytic converter must be warmed to efficiently reduce the emissions. The cold start strategy is to reduce the amount of time it takes to warm the catalytic converter.
What causes a p1400 Chevrolet to get a trouble code?
The second method is to adjust idle speed and spark timing. It’s this second method that can give you a P1400 Chevrolet trouble code. Specifically, when the PCM senses a cold start (any time an engine has been sitting for 3 or more hours) the PCM increases idle speed and retards spark timing.
How much does it cost to diagnose p1400 Ford code?
The cost of diagnosing the P1400 FORD code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. When is the P1400 FORD code detected? Differential Pressure Feedback Electronic (DPFE) circuit low voltage detected
What does the code p1400 on a PCM mean?
WHAT DOES CODE P1400 MEAN? CHECK ENGINE LIGHT COMES ON AND STAYS ON. Customer Concern: Repeat Powertrain Control Module (PCM) code: P1400. The vehicle runs OK otherwise. Tests/Procedures: 1. Check that the Engine Coolant Temperature (ECT) sensor and the Intake Air Temperature (IAT) values match on cold start. 2.
What does the p1400 code on my engine mean?
P1400 Meaning. The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small amounts of exhaust gas back through the upper intake to get mixed in with the air/fuel charge.
What is the dpfe sensor on Ford p1400?
The system employs an EGR Valve, an Electronic Vacuum Regulator (EVR), and a Delta Pressure Feedback EGR sensor (DPFE). The DPFE Sensor measures EGR flow across an orifice located inside the special EGR Tube.
How much does it cost to repair a Ford p1400?
The cost of diagnosing the P1400 FORD code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
What does GM p1400 cold start control system do?
GM defines a P1400 as Cold Start Emission Reduction Control System. That may sound like Greek to you, but there’s a method to their madness. A catalytic converter must warm up sufficiently to process excess hydrocarbons. One way to do that is to increase idle speed and retard timing during a cold start.
