Common Issues with a Honda S2000 Boost Gauge
Designed to ensure that your car's turbo is running at peak levels, the Honda S2000 boost gauge is important in monitoring your supercharger or turbocharger's performance. Basically, a high-performance engine needs more compressed air to allow for more fuel to ignite, and a boost gauge allows you to monitor if the right amount of air is injected into the combustion chamber. Boost gauges are also prone to breakdown. Its pressure sensor mechanism and vacuum lines may fail, causing an incorrect boost value, which can cause irreversible damage to your engine. Here are some of the most common boost gauge issues, and the possible factors behind them:
If you notice that your boost gauge's panel isn't lighting up, it could be due to faulty wiring or relays. Pinched wires, loose relays, and improper installation are the most common reasons why boost gauge displays don't work. Inspect the wires connected to the boost gauge, all the way to the pressure sensor and fuse box. Check for pinched wires and loosen them up. Make sure to run through the relays and fuses and then replace burnt ones immediately. If the boost gauge still doesn't work, consider replacing it with a brand new one.
Invalid pressure reading
When you see that your boost gauge isn't giving you a precise pressure reading, it could be due to a bad or leaking vacuum line. You may experience rough idling, a choking turbocharger, or stalling while driving at highway speeds. Make sure to check the hoses connected to the boost gauge and engine. Cracked or worn-out pressure lines may cause the gauge to give out invalid readings. Immediately replace worn-out lines and secure them tightly. If your boost gauge still gives you false pressure readings, check your car's turbo or supercharger system for possible problems.
Error and fault codes
Fault and error codes are caused by several factors, including a faulty pressure sensor. Electronic boost gauges monitor the boost produced by the engine's pressure sensor, and if the air output and compression is lower than normal, fault codes may be generated. Refer to your owner's manual to interpret the error codes and perform the troubleshooting recommended by the manufacturer.
