Sled was gone through before season cleaning exhaust valves, replacing exhaust valve gaskets checked fuel pressure, replaced voltage regulator. The sled would go into limp mode at around 7000 rpm everytime no mater what. This was on last years fuel with stabil. Filled up with fresh 93 and ran perfect until it got down to a quarter tank and went into limp mode at 7000 or so rpm. Fresh gas was added and its still goin into limp mode. The check engine light continually flashes. Im goin to drain all fuel and refill today ans see what happens. What else can i check. And is there a computer scanner a person can by to read these codes.
If you still have the check engine light you can count the number of times it blinks to get a code. It will blink between 1 and 8 times and then pause between. If there is more than 1 error it will take turns between the 2 codes.
I got this from a google search:
Sensor LED Blinking Explanation
1 Throttle Position Sensor (TPS) 1 time Sensor signal is below 0.7 volts or above 4.39 volts.
2 Water Temperature Sensor 2 times Sensor signal is below 0.1 volts or above 4.8 volts.
3 Intake Air Temperature Sensor 3 times Sensor signal is below 0.19 volts or above 4.9 volts.
4 Barometric Pressure Sensor 4 times Sensor circuit voltage is below 1.25 volts or above 3.23 volts.
5 Exhaust Temperature Sensor 5 times This blink code is set if the engine has been running above 3000 RPM for more than 2 minutes and the sensor voltage is below 0.06 volts or above 4.9 volts.
6 Detonation Sensor 6 times This blink code is set if the engine speed is above 6000 RPM and the DET signal is below 1.23 volts or above 4.3 volts for more than 2 seconds.
7 times is not used --
8. EV Solenoid (O.L.) 8 times An “open circuit” condition is detected in the exhaust valve solenoid control.
These codes will all reset when the cause of the problem is corrected.
