| 94 2.0L VIN H MFI |
|---|
| 13 | Oxygen sensor voltage stays between 0.35 and 0.55 volts for 10 seconds
after engine has been running for 40 seconds with a throttle angle above
5%. |
| 14 | Coolant temperature sensor signal indicates a temperature of over
291° F or under -22° F after the engine has been running for 2 minutes. |
| 19 | The 58X signal (58 pulses per crank revolution) did not match with
engine RPM. |
| 21 | TPS voltage was above 2.5 volts or below 0.2 volts for 5 seconds when
the MAP sensor signal showed manifold vacuum to be 15 pounds or more. |
| 24 | Vehicle speed sensor signal showed less than 5 MPH. Vehicle was not
in park or neutral and had an engine speed between 1600 and 4400 RPM
and the MAP signal showed high manifold vacuum. |
| 32 | EGR open command did not change the fuel mixture when the command
was given during off idle operation. EGR opening should cause the mixture
to be slightly richer because of the low oxygen content of exhaust gas. |
| 33 | MAP sensor signal voltage was too high (low vacuum) for 5 seconds
when throttle opening was under 5%, or MAP sensor voltage was too low
(high vacuum) when throttle opening was greater than 15%. |
| 44 | Oxygen sensor voltage was under 0.35 volts for 25 seconds after the
engine had been running for at least 2 minutes with a throttle angle
above 5%. |
| 45 | Oxygen sensor voltage was over 0.55 volts for 51 seconds of closed
loop operation after the engine had been running for at least 2 minutes
with a throttle angle above 5%. |
| 51 | ECM error. |
