Rodeo LSE 4WD V6-3.2L (2000)
Usually P1271, P1273 and P1275 are stored in memory. The code(s) set at key-up and are related to correlation errors. Remember, when the TP1
and the TP2 or the AP1 and the AP2 actual readings are added together, the total should be 100%. If the variation is at or exceeds 5%, a P1275 may
set. In order to duplicate the condition, install the Tech 2 or the PowerLink and perform a quick-snapshot prior to the initial cold start. Look for a
glitch on the AP1 reading
^
The second complaint will usually be related to the MIL and Reduced Power Light with codes for throttle position sensors or accelerator position
sensors. The customer will also complain of lack-of-power. This condition is most likely related to loss of a five-volt reference. Therefore one AP
sensor and one TP sensor are affected. A P1275 is definitely present.
^
The third complaint will also be related to the Reduced Power Light being on, the MIL on and the vehicle in a "Forced Idle" mode. This may be
related to loss of both five-volt references, loss of both AP sensor readings, and/or loss of both TP sensor readings.
^
The final complaint is also related to a Reduced Power Light present. the MIL on, and a forced shut-down condition. The vehicle will crank but will
not start. This condition may be related to a Throttle Motor condition and/or the loss of either or both five-volt references for the Throttle Position
Sensors and the Accelerator Position Sensors.
