please do fix code 22 errors
as each time that happens the ECU goes to limphome mode and timing advance is dead in that mode. the FSM tells you that clearly.
DTC must not be ignored on this car, or it will misfire, for sure.
the ECU seeing code 22 then runs the mimic mode of a dead TPS, a very very crude thing this, using MAF as a fake TPS is what it does.
TPS is prime sensor and most not ever fail for any reason, or you ECU can not run in NORMAL MODE.
consider this, what if this PC had no limphome mode nor mimic dead sensors modes
and TPS failed
it the engine stalls. off idle. (as enrich mode is now dead, )
The TPS is NOT optional on any EFI car;.
what is TPS TP voltage at idle.? 1v? pin 3.
meter neg black lead to battery minus
and red test lead tip with needle back probing pin 2.
there is no CAS crank angle sensor(CKP) on this year car
the CMP is in the distributor and is not sold by it self, in stores.
this is the FSM page for your car for TPS calibration. pin 1 is down. pin 2 is idle switch.
on running engine , not pulled connector like below
1: ground, 0volts
2: 0v ,idle switch closed. switch, 5v wrong. (code 44./45) (we calibrate just this pin)
3: TP pin output about 1v, not 0v not 5v. (0v is code 22) also todays world called THROTTLE ANGLE PIN. TP= throttle position.(old name)
4: +5vdc power from ECU if this fails sure code 22. (spec is 4.75 to 5.25vdc) this is only power. to the TPS.
the TPS can be bench calibrated easy in ohms mode. sure can.
on modern cars, there is no idle switch at all .
the ECU auto-calibrates the TPS every time you key on. (your car is not modern)
