My TPS NEVER goes to 0%, i've tried cleaning it, changed the IAC, etc....
It is always at 1% when i'm off the throttle, and goes to 101% when mashed.
I think this could be why my car idles 20% TOO rich on all of the base maps provided by hondata.
I tried fixing it by adjusting the TPS Sensor to minimum 1% and max 101%.
Also, sometimes when i decel in gear, at least once during each driving cycle, the MAP and CAM angle Jumps, the cam angle spikes at 50 for a split second and falls right back down and the map goes up maybe 10 kpas.
I tried changing the map sensor, but no luck.
Every base map from hondata runs about 25% too rich on my car.
But now i'm beginning to wonder.
Is there something wrong with my car, I've replaced both my map sensor and primary 02 but still have this problem.
And now that i'm thinking of it, before i got k-pro. I had a reflash, and when i used to take off at low rpms, my car would choke on too much fuel and jerk a little. If all of hondata's calibrations run rich on my car, then i'm guessing their reflash would have done the same. I always got a CEL saying my primary o2 was stuck rich (which is why i changed it) but now from watching the hondata dvd, it says that the CEL is usually thrown when the l. trim reaches +/- 20 %
What could the problem be?
Few problems i'm having.
Knock Sensor / TPS Parameters
Previous Top Next
Knock sensor parameters.
Always enable the knock sensor.
Flashing the MIL (check engine light) when the ECU detects knock will help alert you if the engine is knocking.
TPS range
This allows the throttle position sensor to be adjusted or re-scaled to suit slight variations in TPS sensor position or range. The normal TPS voltage range is 0.50V (closed) to 4.50V (open).
Minimum reading - is the default TPS reading when the throttle is fully closed. The Set button
Maximum reading - is the default TPS reading when the throttle is fully open.
Read - reads from the ECU and then sets either the minimum or maximum throttle to the current TPS reading. When setting the minimum reading, ensure the throttle is fully closed, when setting the maximum, open the throttle fully. This should be not be done with the engine running.
Defaults - resets the minimum and maximum settings to standard defaults.
Notes:
1. The minimum and maximum values are based on the default TPS range, and so will only be the same as the current TPS reading when the default TPS scale settings are in use.
2. This feature is not designed to correct a faulty TPS. The TPS must read at least 60% of the standard range.
3. If your TPS reads 100% when closed and 0% when open, re-pin the connector, swapping the VCC and GND pins.
4. If you generate TPS error codes then you have incorrect adjustments entered. Set the TPS settings to default, and re-adjust.
